Introduction

This instrument is a high-precision, light-weight Chroma Meter developed for Absolute Measurement and Difference Measurement in a wide range of fields. Measurement can be made in conjunction with a multi-functional data processor or with the Measuring Head alone.

Layout of This Manual

• This manual describes the CR-400 and CR-410. The CR-400 is used for illustrations, and any differences have been pointed out clearly so the manual may be used equally for both models.
• The manual is divided into two sections covering the Measuring Head and one section on the data processor. See following chapters for your use.

Chapter 1 Measuring Head 1 (P.21-)

When using the measuring head alone.

Chapter 2 Measuring Head 2 (P.53-)

When using the measuring head separately from the data processor after setting.

• The measuring head cannot be set by itself, but functions which run by setting the head using the optional CR-400 utility software CR-S4w or the Color data software ChromaMagic CR-S3w are described.

Chapter 3 Data Processor (P.57-)

When using the measuring head and the data processor together.

(Data Processor)

key: moves cursor or scrolls screen left and right.
key: moves cursor or scrolls screen up and down.

• This instrument and the AC adapter supplied as a standard accessory have been designed exclusively for indoor use.
• Do not leave the CR-400/410 in direct sunlight or near sources of heat, such as stoves etc. The internal temperature of the instrument may become much higher than the ambient temperature in such cases.
• Do not use the CR-400/410 in areas where dust, cigarette smoke, or chemical gases are present. Doing so may cause deterioration in performance or breakdown.
• Do not use the CR-400/410 near equipment which produces a strong magnetic field (such as speakers, etc.)
• The CR-400/410 is classified as an Installation Category II (equipment which is powered by an AC adapter connected to a commercially available power source).
• The CR-400/410 is classified as a Pollution Degree 2 (equipment which may cause temporary electrical hazards due to contamination or condensation, or products which are used in such an environment).
• Do not use the CR-400/410 at altitudes of higher than 2000m .
• Use this instrument at ambient temperature between 0 and 40^ and relative humidity 85% or less (at 35^ ) with no condensation (*1). Operating this instrument outside specified temperature and humidity range may unsatisfy its original performance.

*1 Operating temperature/humidity range of products for North America: between 5 and 40^ and relative humidity 80% or less (at 31^ ) with no condensation

• Do not subject the CR-400/410 to strong impact or vibration.
  Doing so may cause deterioration in performance or breakdown.
• The measurement aperture should be protected from dirt and strong impacts. Always attach the protective cap when not in use.
• The CR-400/410 may cause interference if used near a television, radio, etc.
• Due to the effect of electrostatic discharge on or in the vicinity of CR-400, erroneous can occur. In this case please repeat the last measurement. If strong static electricity is received at the moment measurement is made, the measurement values may be adversely affected, but the following measurement will be ok.

• When using the Measuring Head upside-down, make sure no dirt or dust get into the aperture.
• When using the instrument for long periods of time, the displayed value may change depending on changes in the environment. Therefore, in order to achieve accurate measurements, we recommend that white calibration be done regularly using the white calibration plate. Doing this will automatically correct other calibration channels, so there is no need to calibrate them.
• Changes in the temperature will cause the color of the specimen to change, resulting in changes in the measurement data even if white calibration has been done. Therefore, calibration, setting of color difference target colors, and measurement should all be done at the same temperature.
• When performing continuous measurements, remove the batteries and use the AC adapter.

• Although this instrument is designed for increased accuracy in operations by internally calculating more digits than are actually displayed, some operation errors may occur in the minimum number of digits during rounding off, color space conversion, and in other situations.

• The white calibration plate is placed near the middle. When doing a calibration, use the area near the middle.
• Do not allow the white calibration plate to get scratched or stained.
• If you are not going to use the white calibration plate, close the cover to the white calibration plate to prevent entry of ambient light, as any areas exposed to such light will discolor.

• This roll paper is special paper (thermal paper) which displays color as the result of a heat-induced chemical reaction.
• Do not store in hot and/or humid places.
• Do not expose to direct sunlight, fluorescent light, or other outside light for long periods of time.
• Using roll paper which has become discolored because of the way it was stored will result in printing which is difficult to read. Use new roll paper whenever possible.
• Printed data may become difficult to read because of the way the paper has been stored. We recommend you copy any data for long-term storage.

• Since the printer uses a thermal mechanism, the ambient temperature may affect the speed and/or consistency of print.

• Make sure that the power switch is set to OFF when the CR-400/410 is not in use.
• Always use the AC adapter (AC-A17) supplied as a standard accessory and connect it to an AC outlet of the rated voltage and frequency.
• Use an AC power source which is within 10% of the rated voltage.

• A low ambient temperature will cause a drop in battery performance, with similar results for performance in terms of number of measurements and printing speed and consistency. We therefore recommend you use lithium or nickel metal-hydride batteries which can withstand changes in temperature.

• Measurement data and settings are stored in memory which is backed up by the internal backup batteries. The backup batteries are automatically charged during operation of the instrument, and can retain the contents of memory for 10 months if they have been fully charged. At time of purchase, the batteries may have already been partially discharged, so turn the power on to charge them. Charging of the backup batteries is performed continuously while the instrument is switched on, even while the instrument is being used. The batteries can be fully charged about 20 hours, and there is no danger of overcharging.
• Do not replace the internal backup batteries (type: ML2020 3V) yourself. Contact the nearest Konica Minolta authorized service facility to replace the backup batteries.

• We recommend that you backup all important data and store it separately.

• The CR-400/410 should be stored at temperatures between -20 and 40^ and a maximum relative humidity of 85% . Do not store it in areas subject to high temperatures, high humidity, or rapid changes of temperature, or where condensation may occur. For added safety, we recommend that it is stored with a drying agent at room temperature.

• Do not leave the CR-400/410 inside a car or in the trunk of a car. Under direct sunlight in summer, the increase in temperature can be extreme and may result in malfunction.
• Do not store the CR-400/410 in areas where dust, cigarette smoke, or chemical gases are present. Doing so may cause deterioration in performance or breakdown.
• When not using the white calibration plate, close the cover and store it.
• Do not throw away the packing materials (cardboard box, cushioning material, plastic bags, etc.). They can be used to protect the instrument during transportation to a service facility for maintenance (re-calibration etc.).
• If you are not going to be using the CR-400/410 for more than two weeks, the batteries must be removed. If the batteries are left in the instrument, leakage may occur resulting in damage to the instrument.

Notes on Cleaning

• If the CR-400/410 becomes dirty, wipe it with a soft, clean dry cloth. Never use solvents such as thinner and benzene.
• If the white calibration plate becomes dirty, wipe it gently with a soft, clean dry cloth. If dirt is difficult to remove, wipe it with lens cleaner and cloth, then dry.
• If the CR-400/410 break down, do not try to disassemble and repair it by yourself. Contact a Konica Minolta authorized service facility.

Preparation

Inserting the Batteries

To supply power to the instrument, the AC adapter (AC-A17) or 4 AAA size batteries must be used. Use either the AC adapter or batteries, according to which suits your application.

WARNING

Do not dispose of batteries in fire, short their terminals, apply heat to them, or disassemble them. Also, do not recharge them. Doing so may cause explosion or heat generation, resulting in fire or injury.

CAUTION

Do not use batteries other than those specified by KONICA MINOLTA. When installing batteries in the instrument, make sure that they are correctly oriented according to the (+) and (-) marks. Failure to adhere to these instructions may cause the batteries to explode or leakage electrolytes, resulting in fire, injury, or air pollution.

Notes on Use

• If you are not going to use the instrument for more than two weeks, make sure that the batteries are removed. If the batteries are left in the instrument for long periods of time, battery electrolyte may leak and damage the instrument.
• Do not touch the terminals inside the battery chamber. Doing so may result in breakdown of the instrument.

Recommended batteries

• Since a low temperature reduces the battery performance, the number of measurements and the printing speed and darkness of the characters also deteriorates. We therefore recommend using lithium or nickel metal-hydride batteries which are good in low temperatures.

[Operating Procedure]

1 Turn the power switch to OFF (O) and open the battery chamber cover on the side of the measuring head.

Battery chamber cover

2 Insert 4 AAA size batteries in accordance with the polarity indications shown in the battery chamber.

Boot switch

Notes on Use

Do not touch the boot switch under any circumstances as this will erase programs and data and cause circuit malfunctions.

3 Close the battery chamber cover.

Battery chamber cover

Using the instrument continuously for long periods of time or transferring data using the RS-232C terminal consumes a lot of electricity, so we recommend you use the AC adapter (AC-A17).

WARNING

Always use the AC adapter supplied as a standard accessory or the optional AC adapter, and connect it to an AC outlet of the rated voltage and frequency. If the AC adapters other than those specified by KONICA MINOLTA are used, this may result in damage to the unit, fire or electric shock.

If the instrument will not be used for a long time, disconnect the AC adapter from the AC outlet. Accumulated dirt or water on the prongs of the AC adapter's plug may cause a fire and should be removed.

Do not disassemble or modify the instrument or the AC adapter. Doing so may cause a fire or electric shock.

The instrument should not be operated if it is damaged, or AC adapter is damaged or if smoke or odd smells occur. Doing so may result in a fire. In such situations, turn the power OFF immediately, disconnect the AC adapter from the AC outlet (or remove the batteries if they are used) and contact the nearest Konica Minolta authorized service facility.

Do not connect or disconnect the AC adapter with wet hands. Doing so may cause electric shock.

CAUTION

When using an AC adapter, make sure that the AC outlet is located near the instrument and that the AC adapter can be connected to and disconnected from the AC outlet easily.

Notes on Use

• Before connecting or removing the AC adapter, make sure that power is turned OFF.

[Operating Procedure]

1 Make sure the power switch is turned OFF (O).

2 Connect the AC adapter connector plug to the AC adapter terminal on the rear of the instrument.

3 Insert the AC adapter power plug to an AC outlet (100-240 Vac).

If the batteries are installed in measuring head and the AC adapter is used, the power is supplied by AC adapter.

[Operating Procedure]

1 Set the POWER switch to (I).

• The measurement screen appears after the start-up screen.
• The PC mode screen appears when in PC mode.

[Operating Procedure]

1 Set the POWER switch to (O).

Power save mode will be activated if the measurement button and operation keys are not operated for more than three minutes. When in power save, the instrument's ready lamp goes OFF in order to stop recharging the light emission circuit. Power save mode can be disengaged by pressing any of the operating keys or the measurement button. (The key pressed when disengaging will not function.)

Data and settings in the instrument are automatically stored.

The memory is protected if the batteries are in the instrument or it is plugged in to the AC adapter and the power is ON because of power supply to the memory. The instrument also has special internal memory backup batteries, so as long as the batteries are at full charge, the contents of memory are protected for up to 10 months even if the batteries in the measuring head are removed or the AC adapter is not used. (A full charge is achieved when the AC adapter is connected continuously for 20 hours.)

The instrument's language mode is set to English when shipped from the factory.

To set a different language, the DP-400 Data Processor (see P.70 "Setting Language Mode" for details), or the optional CR-400 utility software CR-S4w or Color data software ChromaMagic CR-S3w are required.

Basic Operating Procedure Flow

When using the instrument for long periods of time, the displayed value may change depending on changes in the environment. Therefore, in order to achieve accurate measurements, we recommend that white calibration is done regularly using the white calibration plate. White calibration should also be done before measuring after a long time has passed since the instrument was last used.

Note

White calibration should be done under the same temperature conditions as measurement.

[Operating Procedure]

Press the Calibration key _AL while in the measurement screen.

• The white calibration screen appears.

No white calibration data has been set.

White calibration data has been set.

• Go to step 3 if white calibration data has been set.

2 Set the data listed on the back of the white calibration plate cover using the key and the Enter key (ENTER).

• The numbers changes 0 9 0 ... (larger) every time the key is pressed.
• Move the cursor using the Enter key (Enter).

[Example]

• Illuminants C: Y = 93.5 x = 0.3114 y = 0.3190

Note

The illuminant is set to default C , so change the data for C . When changing D_65 , the DP-400 data processor is required. (See P72.)

The optional CR-400 utility software CR-S4w and the Color data software ChromaMagic CR-S3w can change Illuminant as well.

3 Place the measuring head vertically above the middle of the white calibration plate.

Note

The white calibration plate is placed near the center. Use the center area when calibrating.

Press the measurement button after making sure the ready lamp is ON.

• Calibration is complete after the lamp flashes three times. The display returns to the measurement screen.

User Index

• It is possible to regist an operational expression based on the color space to the measuring head. Simply displaying the user's own index as measurement results eliminates the need to do calculations based on the measurement values, making more convenient color management on the job.
• A PC is used to write the operational expression to the measuring head, and up to six can be registered. This can be done automatically by connecting a data processor to the measuring head.
• The optional CR-400 utility software CR-S4w and Color data software ChromaMagic CR-S3w are needed to write the user index.

See the operation manual for the CR-400 utility software CR-S4w for details on how to write the user index.

Data can be transferred between the instrument and a PC by connecting the instrument's RS-232C terminal to a PC.

We recommend using the AC adapter (AC-A17) when connected to a PC because of the higher power consumption involved.

By connecting the instrument to a PC/AT compatible PC using the optional RS-232C cable CR-A102, the data stored in the instrument memory can be transfer each other.

Use the optional CR-400 utility software CR-S4w and the Color data software ChromaMagic CR-S3w when connecting the instrument to a PC.

The followings can be used in PC mode:

1. Outputting measurement and target color data to a PC
2. Reading target color data from a PC.
3. Changing Settings
4. Registering a User Index

See P.50 "Changing to PC Mode" for details.

Notes on Use

• When connecting, make sure that the connectors are correctly oriented and fastened securely with screws.
• Before connecting, make sure that the power to both the instrument and PC is turned OFF.
• Hold the connector when connecting or disconnecting. Do not bend, pull, or apply undue pressure to the cord, as this may cause it to break.

Preparation

Inserting the Batteries

To supply power to the instrument, the AC adapter (AC-A17) or 4 AA size batteries must be used. Use either the AC adapter or batteries, according to which suits your application.

WARNING

Do not dispose of batteries in fire, short their terminals, apply heat to them, or disassemble them. Also, do not recharge them. Doing so may cause explosion or heat generation, resulting in fire or injury.

CAUTION

Do not use batteries other than those specified by KONICA MINOLTA. When installing batteries in the instrument, make sure that they are correctly oriented according to the (+) and (-) marks. Failure to adhere to these instructions may cause the batteries to explode or leakage electrolytes, resulting in fire, injury, or air pollution.

Notes on Use

• If you are not going to use the instrument for more than two weeks, make sure that the batteries are removed. If the batteries are left in the instrument for long periods of time, battery electrolyte may leak and damage the instrument.
• Do not touch or short-circuit the terminals inside the battery chamber. Doing so may result in breakdown of the instrument.

Recommended batteries

• Since a low temperature reduces the battery performance, the number of measurements and the printing speed and darkness of the characters also deteriorates. We therefore recommend using lithium or nickel metal-hydride batteries which are good in low temperatures.

[Operating Procedure]

1 Turn the power switch OFF (O) and open the battery chamber cover on the bottom of the data processor.

Battery chamber cover

2 Insert 4 AA size batteries in accordance with the polarity indications shown in the battery chamber.

Measuring Head

See P.23 "Inserting the Batteries" for details on the measuring head.

If the connected measuring head and data processor are used, the power is supplied from data processor to measuring head. The power is not supplied from measuring head to data processor.

Using the instrument continuously for long periods of time or measuring or printing so we recommend you use the AC adapter (AC-A17).

WARNING

Always use the AC adapter supplied as a standard accessory or the optional AC adapter, and connect it to an AC outlet of the rated voltage and frequency. If the AC adapters other than those specified by KONICA MINOLTA are used, this may result in damage to the unit, fire or electric shock.

If the instrument will not be used for a long time, disconnect the AC adapter from the AC outlet. Accumulated dirt or water on the prongs of the AC adapter's plug may cause a fire and should be removed.

Do not disassemble or modify the instrument or the AC adapter. Doing so may cause a fire or electric shock.

The instrument should not be operated if it is damaged, or AC adapter is damaged or if smoke or odd smells occur. Doing so may result in a fire. In such situations, turn the power OFF immediately, disconnect the AC adapter from the AC outlet (or remove the batteries if they are used) and contact the nearest Konica Minolta authorized service facility.

Do not connect or disconnect the AC adapter with wet hands. Doing so may cause electric shock.

CAUTION

When using an AC adapter, make sure that the AC outlet is located near the instrument and that the AC adapter can be connected to and disconnected from the AC outlet easily.

Notes on Use

• Before connecting or removing the AC adapter, make sure that power is turned off.

[Operating Procedure]

1 Make sure the power switch is turned OFF (O).

2 Connect the AC adapter connector plug to the AC adapter terminal on the rear of the instrument.

Insert the AC adapter power plug to an AC outlet (100-240 Vac).

• If the batteries are installed in both measuring head and data processor and the AC adapter is used, the power is supplied by AC adapter.
• If the connected measuring head and data processor are used, the power is supplied from data processor to measuring head.

If the batteries are installed in data processor and the AC adapter is used, the power is supplied by AC adapter. The power is not supplied from measuring head to data processor.

Precautions regarding connecting and disconnecting the measuring head and data processor.

• Before connecting and disconnecting, make sure that the power to both the measuring head and dataprocessor is turned OFF.
• Hold the connector when connecting or disconnecting. Do not bend, pull, or apply undue pressure to the cord, as this may cause it to break.
• When using the measuring head alone or replacing it, some items in the data processor settings may be changed at the connection. See P.64 "Setting Status of Connected Measuring Head and Data Processor" for details on the default values and status during connection of all settings shared by the measuring head and data processor when connected.
• We recommend using the measuring head and the data processor with the same settings.

[Operating Procedure]

1 Make sure the power switches on the measuring head and data processor are OFF (O).

2 Insert the one side of the RS-232C cable to the RS-232C terminal on the measuring head.

Power switch

[Operating Procedure]

1 Set the POWER switch to (O).

Power switch

Note

• You do not have to turn the measuring head and data processor ON/OFF in order when they are connected.

The instruments recognize connecting status automatically.

• To turn OFF the power switch, observe the following instructions:

1) Do not turn OFF the data processor power switch immediately after execution of measurement (including calibration and target color measurement for update).
2) Do not turn OFF the data processor power switch when transferring data from the measuring head.
3) Do not turn OFF the measuring head power switch when automatic averaging measurement is in progress with the data processor.

In the above cases 1) and 2), the data processor receives measurement data from the measuring head, and stores the data into the data processor internal memory after necessary processing. If the power switch is turned OFF before completion of data storage, the data may be lost, or incompletely stored. If an incomplete storing condition is detected at the next startup, the data processor may initialize all stored data because it recognizes corruption of stored data. (For initialization, see NOTE in on P.66.) In case of the above 3), the data processor may not accept key entry even after the measuring head is restarted and re-connected. In such a condition, restart the data processor.

The data processor recognizes connecting status to measuring head automatically and can communicate with measuring head after power is ON.

The following screens appear while the data processor reads settings of measuring head.

Reading time depends on number of color difference target color data of measuring head.

Measuring head is connected

Measuring head is removed

Measuring head

"DP MODE" is displayed in measuring head LCD.

Only measurement button functions.

Data processor is connected

• Power save mode will be activated if the measurement button and operation keys are not operated for more than three minutes. When in power save, the power save screen appears. Power save mode can be disengaged by pressing any of the operating keys or the measurement button.

In measuring with the timer, remote mode or printing, the auto power save function will not operate.

If the power-saving function is activated when an error screen is displayed, the error screen is retained without showing the power-saving mode. In this case, pressing any operation key or measurement button cancels the power-saving mode, and displays the error screen. (The screen indication does not change.) If the operation key is pressed again, the display returns to the original screen.

Data and settings in the instrument are automatically stored.

The memory is protected if the batteries are in the instrument or it is plugged in to the AC adapter and the power is ON because of power supply to the memory. The instrument also has special internal memory backup batteries, so as long as the batteries are at full charge, the contents of memory are protected for up to 10 months even if the batteries in the measuring head are removed or the AC adapter is not used. (A full charge is achieved when the AC adapter is connected continuously for 20 hours from when the power is turned on.)

Note

If the data processor is left for a long period with the power switch turned OFF, electricity is discharged from the memory backup battery, disabling data backup. In this case, data stored in the memory will be corrupted. If the data processor is started in this condition, the data processor initializes all data stored in the memory. In addition to all items described in "Initial Setting" on P.76, the following items will be initialized.

1) Date/time will be initialized to "2002/01/01 00:00".
2) The language setting will be initialized to "ENGLISH".

Basic Operating Procedure Flow

When using the instrument for long periods of time, the displayed value may change depending on changes in the environment. Therefore, in order to achieve accurate measurements, we recommend that white calibration is done regularly using the white calibration plate. White calibration should also be done before measuring after a long time has passed since the instrument was last used.

Note

White calibration should be done under the same temperature conditions as measurement.

[Operating Procedure]

1 Press the Calibration key Calibrate while in the measurement screen.

• The white calibration screen appears.

No white calibration data has been set.

White calibration data has been set.

2 Set the calibration data listed on the back of the white calibration plate cover using the key and the numeric pad.

• The cursor moves automatically to the next position when setting data using the numeric pad.
• Use the to move the cursor to make corrections.
• Go to step 3, if white calibration data has already been set.

[Example]

• Illuminants C

Y = 93.5 x = 0.3114

y=0.3190

• Illuminants D_65

Y = 93.5 x = 0.3140

y=0.3318

Note

After the initial setting is complete, the illuminant is set to C , so set the data for C . When using D_65 , change the setting to "D65" before calibration as described in steps 1 to 4 on P.72 "Basic Setting 5) Illuminant". After this, return to this page and set the data for D_65 .

• See P.76 "Initial Setting" and P.72 if illuminant is changed after calibration.

3 Place the measuring head vertically above the middle of the white calibration plate.

Note

The white calibration plate is placed near the center. Use the center area when white calibrating.

4 Press the Measure/Enter key (or measurement button on the measuring head) after making sure the ready lamp is ON.

• Calibration is complete after the lamp flashes three times. Complete sound beeps and the display returns to the measurement screen.

The illuminant lamp flashes three times.

Measurement screen

Note

• Do not move the measuring head during calibration.
• If selected in user calibration, select "white calibration plate" following steps 1 to 4 on P.137 "Setting the Manual Select Calibration" to set to the white calibration.

With this, white calibration is finished.

When measuring the chroma values (absolute values), perform P.88 "Absolute Measurement". To measure the color difference between a color difference target color and a specimen, perform P.90 "Setting the Color Difference Target Color" and P.98 "Measuring the Color Difference".

This instrument can measure reflected object color with the color spaces, XYZ, Yxy, Lab, Hunter Lab, LC*h, Munsell, and others. (See P.78 "Selecting the Color Space" for details)

Note

Mesurement should be done under the same temperature conditions as calibration.

• When data protection is set to OFF and data quantity exceeds 2000 items, the oldest page that contains measurement data will be deleted, and a data storing area will be secured. (If the page to be deleted is page 0, the relevant page remains, but the measurement data on this page will be deleted.) If there is no page that contains measurement data other than the current page, the oldest data on the current page will be overwritten.

• When data protection is set to ON, a measurement error occurs, and the "Data Memory Full" error message appears.

[Setting conditions] Select L^a^b^* color space and absolute display

• Press the Print/Paper Feed key 3Cost anytime you want to print out the data displayed in the LCD.

The instrument can measure the color difference between the color difference target color and a specimen using color spaces, (XYZ) , (Yxy) , (L^a^b^) , Hunter Lab, (L^C^*H) , and others. (See P.78 "Selecting the Color Space" for details.)

Before measuring color difference, you must set the color difference target color in the measuring head. 100 color difference target colors can be set to nos. T00 to 99.

The color difference target color number can be changed to a name for the sake of convenience.

The color difference target color number can be set independently of the page function (P.105).

This instrument can make judgments based on a color difference tolerance for the measurement value of the color difference target color.

When measuring color difference, if the measured value is within the color difference tolerance set for the color difference target color, "PASS" is displayed, if it is at the warning level "WARN", and if it is out of the range "FAIL" is displayed is displayed. It is possible to judge whether the data is close to the tolerance by setting an appropriate warning level (i.e. what percent of the tolerance). If the buzzer is set to ON, an error beep sounds when the judgment is "FAIL".

The four methods for setting the color difference tolerance for judgment are shown below.

1) Elliptical tolerance: allows setting a tolerance on the basis of an ellipse. This makes it possible to display the color difference in results closer to what is visible to the naked eye.
2) Box tolerance: allows setting a tolerance independently for each component like “L”, “a”, “b*”, etc. This type is easy to understand and makes calculation easy, too.
3) E : allows setting a tolerance based on the color difference ( E ) with the target color.
4) Box tolerance and E : allows setting a tolerance combining (2) and (3) above.

"O" is displayed if no tolerance is set.

It is possible to set various color difference tolerance for one set of color difference target color data. However, the following restrictions apply to the type of color difference tolerance which can be set depending on the color space.

See P.80 "Color Space and Color Difference Setting" for details.

• None of the color difference tolerance above (1 - 4) can be set for "Munsell" or "User Index."
• Only 2 above can be set for "CIE WI/Tw", "WI E313", "YI D1925", and "YI E313".

E in 3) and 4) above is displayed as follows depending on the set color space.

E^* , E, E94 , E99 , E00 , CMC

Even if the color space is changed after the color difference tolerance is set, it is managed using the color space present when the tolerance was set. Therefore, judgment is made on the measurement values calculated internally on the basis of the color space at the time the tolerance was set, and not the color space selected in the measurement screen. Further, the color space systems at time of setting are used for redisplaying the existing tolerance and input rules when changing settings.

It is not possible to input a tolerance for only one component. (for Ex. L* only) In this case, set a large tolerance for the other components.

Although it is possible to change the type or value of the tolerance after the color difference tolerance is set, it is impossible to cancel it. To cancel the color difference tolerance, it is necessary to either select a color difference target color for which a tolerance has not been set or delete the color difference target color for which the tolerance has been set.

The following description uses the “ L^a^b^* ” color space for example.

The input ranges for the set values are as follows.

(Tolerance) Y: 0.01 to 99.99, xy: 0.0001 to 0.9999, other than Yxy: 0.05 to 80.00

(Offset) -5.00 to +5.00 (should be within tolerance)

(Rotation) -45 to +45

(Warning level) 10 to 100%

Note

Do not enter "space" for color difference tolerance. If you enter "space", it will be processed as a numeric value "0". For example, if you enter 5..00 (".." means "space") by mistake, though you intended to enter 5.00, the setting value will be 50.00 against your intention.

Elliptical tolerance

This judges whether or not the value of the measured color difference is within the range of the elliptical tolerance set for the color difference target color. When setting an elliptical tolerance, besides the tolerance value, an offset and a rotation can also be set.

If the set color space is "LCh" the col or difference tolerance is set along the "Lab*" color space axis, and if the set color space is "L99C99h99" then the "L99a99b99" color space axis is used.

See P.80 "Color Space and Color Difference Setting" for details.

Set a color difference target color ahead of time before setting an elliptical limit.

Since the color difference graphs are displayed in two dimensions, the fail judgment data may sometimes be displayed as plotted inside the tolerance in each graph.

User Index

• It is possible to resist an operational expression based on the color space to the measuring head. Simply displaying the user's own index as measurement results eliminates the need to do calculations based on the measurement values, making more convenient color management on the job.
• A PC is used to write the operational expression to the measuring head, and up to six can be registered. This can be done automatically by connecting a data processor to the measuring head.
• The optional CR-400 utility software CR-S4w or Color data software ChromaMagic CR-S3w is needed to write the user index.

See the operation manual for the CR-400 utility software CR-S4w or Color data software ChromaMagic CR-S3w for details on how to write the user index.

Data can be transferred between the instrument and a PC by connecting the instrument's RS-232C terminal to a PC.

When using the instrument continuously for long periods of time or when performing data transfer using the RS-232C terminal, we recommend using the AC adapter (AC-A17) when connected to a PC because of the higher power consumption involved.

By connecting the instrument to a PC/AT compatible PC using the optional RS-232C cable CR-A102, the data stored in the instrument memory can be sent to a PC.

Use the optional CR-400 utility software CR-S4w or the Color data software ChromaMagic CR-S3w when connecting the instrument to a PC.

The followings can be used in remote mode:

1. Outputting measurement and target color data to a PC
2. Deleting measurement data

See P.129 "Changing to Remote Mode" for details.

Notes on Use

• When connecting, make sure that the connectors are correctly oriented and fastened securely with screws.
• Before connecting, make sure that the power to both the instrument and PC is turned OFF.
• Hold the connector when connecting or disconnecting. Do not bend, pull, or apply undue pressure to the cord, as this may cause it to break.
• Do not touch the connector terminals with your hand. Doing so may cause them to get dirty or subject them to excessive force.
• Make sure that the cable is long enough. Tensioning the cable may cause connection failure or wire breakage.

• If optional RS-232C cable CR-A102 is not used, make sure the cable specifications match the pin number/signal connection diagram for an RS-232C cable below. An inappropriate cable will prevent data from being input and output properly and may cause malfunctions.

Chapter 4

-- Description --

Principles of Measuring

The measuring head measures a specimen, gets the color information from the specimen, converts it to one of the various display modes in the measuring head, and displays it. Also the data processor converts data to one of the various color space modes, displays it, and prints it.

The measuring head is divided into the specimen measuring part which measures the reflected light from the specimen and the monitoring illumination part which directly measures the light from the illumination light source. Each measuring part is equipped with sensors with equal color function 2 ( long wavelength side), , and responses, which are the spectral response for a standard observer and (this instrument uses a spectral response for a CIE 19312^ observer).

By measuring the illumination light source with the monitoring illumination part, it is possible to get data unaffected by subtle changes in the illumination light source.

The circuit offset influence is eliminated by applying the following formulas to the specimen measuring part measurement data (X2s^,Ys^,Zs^) and the monitoring illumination part measurement data (X2r^,Yr^,Zr^) gotten when illuminating, and the specimen measuring part measurement data (X2s^ , Ys", Zs") and the monitoring illumination part measurement data (X2r^ ,Yr^ ,Zr^ ) gotten when not illuminating.

$$ \left{ \begin{array}{l} \mathrm {X} _ {2} \mathrm {s} = \mathrm {X} _ {2} \mathrm {s} ^ {\prime} - \mathrm {X} _ {2} \mathrm {s} ^ {\prime \prime} \ \mathrm {Y s} = \mathrm {Y s} ^ {\prime} - \mathrm {Y s} ^ {\prime \prime} \ \mathrm {Z s} = \mathrm {Z s} ^ {\prime} - \mathrm {Z s} ^ {\prime \prime} \end{array} \right. \quad \left{ \begin{array}{l} \mathrm {X} _ {2} \mathrm {r} = \mathrm {X} _ {2} \mathrm {r} ^ {\prime} - \mathrm {X} _ {2} \mathrm {r} ^ {\prime \prime} \ \mathrm {Y r} = \mathrm {Y r} ^ {\prime} - \mathrm {Y r} ^ {\prime \prime} \ \mathrm {Z r} = \mathrm {Z r} ^ {\prime} - \mathrm {Z r} ^ {\prime \prime} \end{array} \right. $$

The following formulas eliminate the influence of subtle changes in the illuminant.

$$ \mathrm {X} _ {2} \mathrm {m} = \frac {\mathrm {X} _ {2} \mathrm {S}}{\mathrm {X} _ {2} \mathrm {r}} \quad \mathrm {Y m} = \frac {\mathrm {Y} \mathrm {s}}{\mathrm {Y r}} \quad \mathrm {Z m} = \frac {\mathrm {Z} \mathrm {s}}{\mathrm {Z r}} $$

_1 data is calculated by multiplying Zm by the constant.

$$ \mathrm {X} _ {1} \mathrm {m} = 0. 1 6 7 2 \cdot \mathrm {Z m} $$

$$ \therefore X m = X _ {1} m + X _ {2} m $$

The tristimulus value (X, Y, Z) are calculated by multiplying the data achieved from the above (Xm, Ym, Zm) by the calibration constant (, , ) .

$$ \left{ \begin{array}{l} X = \alpha \cdot X m \ Y = \beta \cdot Y m \ Z = \gamma \cdot Z m \end{array} \right. $$

These tristimulus value (X, Y, Z) can be converted to various different color spaces.

Illumination Optics of the CR-400

The CR-400 is designed in diffusion illumination 0^ viewing angle geometry (specular component included). This illumination method illuminates the specimen from all directions using illuminants with almost completely equal brightness, and receives the reflected light vertically from the specimen surface. Normally, when looking at color in, say, a department store or an office, the multiple light sources and the light reflected from the walls create diffused lighting conditions. Outside these conditions are also diffused, in this case from the sky, so this method creates realistic lighting conditions. This instrument is therefore very close to normal visual evaluation, and can be used with all types of specimen.

Illumination Optics of the CR-410

The CR-410 can measure wide range with a diameter of 50mm . It can also take average measurements of diffused reflected components with little regular reflection, such as cloth and carpets. It is useful when taking average measurements of relatively wide measurement surfaces, such as fibers, rugs, carpets, and blankets. As shown in the figure, the light from the pulse xenon lamp is diffused using a diffusion plate, and the light with is diffused evenly after passing through the diffusion plate illuminates the measurement surface with a large measurement diameter of 50mm . Of all the light which is reflected from the specimen surface, only that which is reflected vertically from the specimen surface is led through the specimen measurement fiber to the measuring head sensor, where it is calculated and displayed in the LCD as the measurement value. Caution is required here as this structure receives a lot of regular reflected components, so a lot light is received from specimens with flat surfaces, therefore greatly affecting the illuminant color.

It is extremely difficult to perfectly match the spectral response three photoelectric tristimulus colorimeters like this instrument to the CIE 1931 standard observer, creating a slight discrepancy in spectral response. (See Figure.)

CIE 1931 colorimetric standard Observer curves and spectral response of KONICA MINOLTA chroma meter

In color difference measurement, the effects of this slight discrepancy in spectral response is within the scope of measurement accuracy, so it does not present a problem. However, in color measurement, depending on the color of the specimen to be measured, there are times when a slight discrepancy with the value (true value) gotten when measuring using an ideal prism response. There might even appear a similar discrepancy in spectral response when performing measurements using two of the same model instrument, creating discrepancies in the assigned values when using multiple instruments.

When this happens, it is possible to minimize the discrepancy in assigned value by using the user calibration function.

The user calibration is set by measuring a target specimen with a known sensitivity ahead of time and setting this value as a calibration target color in a calibration channel (ch 01-19). This calibration data is then used to correct the assigned value when measuring

Thereby almost the discrepancy eliminates completely in the assigned value when measuring a color close to the target specimen color. This also applies to colors which are far from the target specimen color.

There are two ways of user calibration: the multi-calibration function and the manual select calibration function. Choose whichever is most appropriate for the number or type of colors to be measured.

The multi-calibration function is used to correct the assigned value using the calibration data in all the set calibration channels. It is therefore effective in providing an appropriate correction not only for the vicinity of the calibration target point but also for the value around it.

However, since the correction effect becomes smaller for colors further from the calibration target point, more effective correction can be achieved by selecting a calibration target color which envelops the color to be measured.

This function is useful in the following cases.

1) When measuring many different colors

The narrower the region where the calibration target point is placed is, the greater the multi-calibration effect is.

2) When measuring only certain colors

Setting the optional calibration target color to envelope the color to be measured will achieve a greater multi-calibration effect.

Note

Multi-calibration corrects the measurement value using the calibration data for all set calibration channels. After measuring using the multi-calibration function, adding to or changing the calibration channels will create a discrepancy with the measurement value, even if the same specimen is measured. Note also that color difference target color values which are corrected during measurement do not change thereafter.

Even more accurate correction can be achieved by creating a list of target colors for the same material as the measurement specimen and calibrated by the master body.

The manual select calibration allows the user to select any calibration channel to correct assigned values using only that calibration data in that calibration channel.

A list of the target colors for calibration should be made for the same material as the measurement specimen and attached to the master body.

This function is useful in the following cases.

• When measuring only the same hue

In this case, it is possible to select a color for the user calibration target color which is similar to the measured color.

It is possible to minimize the difference (inter-instrument agreement) in the assigned values between instruments by performing optional calibration as described below, when using multiple instruments.

• When there is a target specimen which is already valued and which is close to the color of the specimen to be measured.
  1) Perform user calibration all bodies with the target specimen using the data for the target specimen which is already valued.
• When there is not a target specimen which is already valued and which is close to the color of the specimen to be measured.
  1) Select a master body.
  2) Measure a specimen which is close to the color to be measured using the master body.
  3) Perform user calibration all other bodies with that specimen. (Calibration data uses measurement data by the master body.)
