To supply power to the instrument, the AC adapter (AC-A17) or four AA-size batteries (Alkaline or NiMH battery is recommended for better service life) must be used. Use either the AC adapter or batteries, according to which suits your application.

Note

• 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 use batteries of different types or mix new batteries with old ones. Doing so may result in battery explosion or reduction of battery life.
• Do not touch or short-circuit the terminals inside the battery chamber. Doing so may result in breakdown of the instrument.

[Operating Procedure]

1 Make sure that power is OFF (i.e. the POWER switch is set to "O").

2 Slide the battery cover on the rear of the instrument to open it.

3 Place four AA-size batteries in the battery chamber. Make sure that the batteries are placed in the correct direction.

4 Align the marker on the battery cover with that on the instrument, and slide the battery cover to close it.

Connecting the AC Adapter

Memo

Use of the AC adapter (AC-A17) rather than batteries is recommended, since more power will be required when the external output terminal is used to output data to an external device or print it.

Note

• To supply AC power to the instrument, always use the AC adapter (AC-A17) supplied with the instrument.(Rated: 5 V, 2.8 A)
• Before connecting or removing the AC adapter, make sure that power is turned OFF.

[Operating Procedure]

1 Make sure that power is OFF (i.e. the power switch is set to "O").

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

3 Insert the AC adapter's power plug to an AC outlet (100-240 VAC, 50-60 Hz).

When turning the power ON for the first time, the display language and measurement mode must be set.

For details, refer to page E-27.

[Operating Procedure]

1 Set the POWER switch to "I".

The power will be turned ON.

Turning Power OFF

[Operating Procedure]

1 Set the POWER switch to “○”.

The power will be turned OFF.

Auto Power Save Function

Power save mode will be activated if the MEAS. button and navigation wheel are not operated for more than three minutes. During power save mode, the flash circuit will not be charged. To cancel power save mode, press the MEAS. button to start measurement.

• If the MEAS. button is pressed to cancel power save mode, start of measurement will be delayed by a few seconds, so keep the instrument still until the lamp flashes and measurement is taken.

System Configuration

Language Mode

Contents on the LCD screen can be displayed in English, Japanese, German, French, Spanish or Italian. In this manual, explanation of operating methods and display is given for English mode.

Measurement Mode

Two measurement modes (COND and TASK) are available with this instrument, and can be switched from one to another.

	Application
COND mode	Normal measurement mode. Measurement can be performed while the conditions are changed. In this mode, up to six sets of conditions (illuminant, observer angle, color space etc.) can be registered.
TASK mode	Special measurement mode. For continuous inspection, this mode allows you to perform measurement while messages indicating the measurement procedure are displayed on the LCD. The messages can be created by use of the previously used software SpectraMagic (Ver.3.2 or higher; except for Ver.3.5) with your PC. In this mode, color differences can be calculated one by one against up to 10 color difference target data. ■Note ·Before starting measurement, tasks (measurement procedure) must be down-loaded from the PC using SpectraMagic (Ver.3.2 or higher; except for Ver.3.5). TASK mode cannot be selected if no tasks have been downloaded. ·During TASK mode, only the data measured last is displayed. Use of SpectraMagic (Ver.3.2 or higher; except for Ver.3.5) allow you to access to previous data in the memory.

Up to six sets of conditions can be registered either in COND or TASK mode.

Target Modes

• The CM-2600d/2500d supports two Target Modes, "defined in COND." mode and "linked to each data." mode, to analyze both measurement data and color difference. As with Language Mode and Measurement Mode, you can select the desired mode when you turn the power ON.
• The default setting is "linked to each data." mode. To switch to "defined in COND." mode or switch between the target modes, you need to follow the procedure to select target mode.
• Depending on the target mode selected, the display and the procedure for some operation for the instrument are different.

Below are some examples of these differences. (For details, see Target Mode in the Appendix.)

• In "linked to each data." mode, the next color difference data number is displayed next to the currently selected color difference data number in the initial settings screen.

When "defined in COND." mode is selected, it is not displayed.

• In "linked with each data" mode, to display the color difference for measurement data, you can only select the color difference for the currently selected measurement data. When "defined in COND." mode is selected, you can freely select the color difference data number after making measurements. You can also display the results of the selection.
• Data storage capacity for the "linked to each data." mode is 1700 pieces, and that for the "defined in COND." mode is 700 pieces.

Note

Once the target mode is changed, previous data will be cleared. It is recommended that you save previous data into other storage media in advance by using the Color Data Software that is optionally available.

Screen Display

The basic screen structure is shown below.

Battery Alarm

When using CM-2600d/2500d with batteries, battery alarm indication appears when their power level lowers.

[Half battery indication]

If this indication (Half battery indication) appears, new batteries should be prepared for replacement in near future. Even with this indication displayed, measurements are still possible.

[Empty battery indication]

If this indication (Empty battery indication) appears, measurement or calibration is no longer possible. Replace batteries with new ones.

Data Saving

Data used with this instrument is saved automatically. Although white calibration data is retained in internal memory even after power is turned off, it is still necessary to repeat white calibration each time you switch the power back on.

So, set another measurement condition according to the procedure given in "Selecting a Measurement Condition" and "Setting a Measurement Condition" (from page E-34). 

Zero Calibration

When you use this instrument for the first time or when you have initialized it, zero calibration must be performed. Zero calibration is also sometimes required when measurement conditions are changed. Once zero calibration is completed, the zero calibration data will be kept even if the power is turned OFF. Thus, it is not necessary to perform zero calibration each time the power is turned ON.

Memo

- The effects of stray light inside the measuring part (i.e. light generated due to the flare characteristics of the optical system) will be compensated automatically by the zero calibration data. - The amount of stray light may change because of dust or dirt which has collected in the optical system, temperature, repeated operation, vibration and shock exerted on the instrument. In this case, performing zero calibration periodically is recommended.

Note

- If the instrument is not used for long periods of time, the zero calibration data stored in the instrument may be lost. If the data is lost, zero calibration must be performed again. - Before starting zero calibration, select the desired MASK/GLOSS setting from M/I + E , M/SCI , M/SCE , S/I + E , S/SCI and S/SCE in the screen. If M/**** is selected, set MAV to the instrument. If S/**** is selected, set SAV to the instrument. For MAV, set the lens position selector switch and Target Mask to MAV. For SAV, set them to SAV. - A lens position error will occur if the lens position does not match the one set in the file, and a calibration error will occur if the Target Mask does not match.

[Setting Procedure]

screen

1 Turn to select one of the conditions (COND1 to COND6), then press


2 Turn to select "CALIBRATION", then press

 - "T*" is the number of the color difference target data for the next measurement. If nothing is selected, "T---" appears. - "T*" does not appear if "defined in COND." mode is selected.

3 Turn to select "ZERO".


4 Direct the specimen measuring port into the air.

 - Never place the specimen measuring port toward a light source. - Keep the specimen measuring port more than 1m away from any reflective items (hands, desks, walls etc.).

5 Make sure that is displayed, then press (MEAS. button).

Zero calibration will be performed. When zero calibration is complete the <CALIBRAITION> screen wil reappear. 

Memo

- Use of the optional Zero Calibration Box ensures proper zero calibration. If Zero Calibration Box is used, remove "Measuring Base". - If does not appear due to the auto power save function, this may be due the fact that it can take time to start zero calibration after is pressed.

Note

- When zero calibration is complete, perform white calibration. Measurement cannot be performed if white calibration has not been completed. - Even though white calibration has been performed after the power is turned ON, if zero calibration has also been performed after that, white calibration must be performed again.

White Calibration

White calibration must be performed prior to start of measurement after the power is turned ON.

Memo

- Own calibration data has been registered to the White Calibration Plate supplied with the instrument. - Although white calibration data is retained in internal memory even after power is turned off, it is still necessary to repeat white calibration each time you switch the power back on. - The reading may fluctuate slightly due to changes in the ambient temperature or due to heat generation caused by repeated operation of the instrument. In this case, make sure to perform white calibration regularly. - White calibration is not required if you just want to see the measured data without performing measurement.

Note

- White calibration must be performed at the same temperature as the one at which measurement will be performed. - Before starting white calibration, make sure that the instrument is sufficiently acclimatized to the ambient temperature. - Before starting white calibration, select the desired MASK/GLOSS setting from M/I+E , M/SCI , M/SCE , S/I+E , S/SCI and S/SCE in the screen. If M/*** is selected, set MAV to the instrument. If S/*** is selected, set SAV to the instrument. For MAV, set the measurement area selector switch and Target Mask to MAV. For SAV, set them to SAV. - A lens position error will occur if the lens position does not match the one set in the screen, and a calibration error will occur if the Target Mask does not match.

[Setting Procedure]

screen 1 Turn to select one of th3e conditions (COND1 to COND6), then press  2 Turn to select "CALIBRATION", then press  - "T*" is the number of the color difference target data for the next measurement. If nothing is selected, "T---" appears.  - "T*" does not appear if "defined in COND." mode is selected.

3 Turn to select "WHITE".

Note that the White Calibration Plate No. is displayed. 

4 Place the instrument on the correct White Calibration Plate (i.e. the calibration plate whose plate No. is displayed in the screen).


5 Make sure that is displayed, then press (MEAS. button).

White calibration will be performed. When white calibration is complete, the measurement screen will reappear.  

Note

The instrument's memory contains the calibration data of the White Calibration Plate supplied with instrument. Therefore, to execute white calibration, be sure to use the White Calibration Plate of the same serial number as the number displayed on the screen.

Memo

- In COND mode, the measurement screen can still be displayed even if white calibration has not been completed. However, it will not be possible to take measurement. (Measured data can still be viewed.) - White calibration must be performed each time the power is turned ON. - To perform white calibration again after the measurement screen is displayed, select "PREV" to return to screen, then restart the procedure from step 2. - If the measurement area or specular component mode is changed in the screen following white calibration, it is necessary to perform white calibration again under those new conditions (i.e. with the newly selected measurement area or specular component mode). - Even if the conditions are changed (e.g. switched from COND2 to COND3) following white calibration, it will be not necessary to perform white calibration again if the measurement area and specular component mode remain unchanged. - If does not appear due to the auto power save function, this may be due the fact that it can take time to start white calibration after is pressed.

Setting a Color Difference Target Data

To measure the color difference between two specimens, the color of one of the specimens must be set as the target color. Up to 1700 target colors can be set for color difference measurement. (700 can be set in the "defined in COND" mode.) To set a target color, follow the procedure given below.

Memo No. 10

- Since tolerances for pass/fail judgment need to be set for each target color, target color data must be set before setting tolerances. - The memory of this instrument can store up to 1700 pieces of data in total, (700 in the "defined in COND" mode). This amount includes the sample data for the COND and TASK modes as well as color difference target data. When some sample data have already been stored, the number of target colors which can be set will be reduced by the number of the sample data.

Note

- Before setting target colors, a measurement condition (COND1 to COND6) must be selected and white calibration performed. - For accurate measurement, make sure to keep measurement conditions (ambient temperature etc.) constant.

[Setting Procedure]

screen 1 Turn to select "TARGET", then press  - "T*" is the number of the color difference target data for the next measurement. If nothing is selected, "T---" appears. - "T*" does not appear if "defined in COND." mode is selected. 2 Turn to select , then press will change to  - "T1" appears instead of "T---" if "defined in COND." mode is selected. 3 Turn to select the desired target color no. (T*) , then press will return to  - Keeping held down to left or right will cause the target color No. to change continuously.

4 Place the specimen measuring port to the specimen.


5 Make sure that is displayed, then press (MEAS. button).

The lamp will flash, measurement will be taken, then the result will appear on the LCD. 

Memo

- The navigation wheel and MEAS. button cannot be used for three seconds after the MEAS. button is pressed, if "UV100%" has been set for "UV SETTING", or for four seconds if "UV0%" or "ADJUSTED" has been set. - If does not appear due to the auto power save function, this may be due the fact that it can take time to start measurement after is pressed.

6 Turn to select "BREAK" or "PREV", then press

To set the next target color, repeat steps 2 to 5. To exit target color setting, select "PREV". 

Memo

- If a target color has already been set for the selected target color no., a message asking you whether you wish to overwrite the target color data will appear. Select "YES" to overwrite (or select "NO" if not) using , then press - If "MUNSELL", "DENSITY (A)" or "DENSITY (T)" has been selected as the color space, it will be possible to set target colors, but no color difference data will be displayed in the measurement screen. In addition, it is not possible to set color difference tolerances. - If "COLOR GRAPH" has been selected as the display mode, it will be possible to set target colors, but color difference cannot be displayed in the measurement screen. - Measurement will no longer be possible once the total number of target color data and measured data reaches 1700 (700 in the "defined in COND." mode). In this case, delete some target color data or measured data.

Switching between the Measured Data screen and the screen

Turning to select "T" and then pressing will cause the measured data screen to change to the screen showing the color difference target data for the currently selected target number which is the target will be used for the next measurement.

Note

If "SPECT. GRAPH" has been selected as the display mode, "T" will not be displayed in the Measured Data screen. Similarly, "BREAK" will not be displayed in the screen. Thus, switching from the Measured Data screen to screen or vice versa, back to the screen once, must be carried out by the method to select the desired screen.

Selecting a Color Difference Target Data

To measure the color difference between two specimens, the target color to be used for measurement must be selected from those set in "Setting a Color Difference Target Data". To select a target color, follow the procedure given below.

[Setting Procedure]

screen

1 Turn to select "TARGET", then press

 - "T*" is the number of the color difference target data for the next measurement. If nothing is selected, "T---" appears. - "T*" does not appear if "defined in COND." mode is selected.

Turn to select "BREAK", then press

The measurement screen will appear. 

Deleting a Color Difference Target Data

There are two methods for deleting target color data. One is to delete the target color data set in "T*" of the measurement conditions (COND 1 to COND 6) one by one. The other is to delete all the target color data set in the instrument.

Note

- When target color data is deleted, its tolerances will also be deleted. - You will not be able to view the color difference for measurement data that used the deleted target color data.

[Setting Procedure]

Display the target color data to be deleted, as explained in "Setting a Color Difference Target Data". 1 Turn to select "DEL", then press  2 Turn to select the desired deletion method, then press 

Deletion Method

- T\* DELETE: Deletes the currently displayed target color data. - If the target color data to be deleted by another "COND*" or "TASK*" has been selected, a message "THIS TARGET IS USED IN OTHER COND OR TASK. DO YOU DELETE IT?" will appear. Select "YES" if you want to delete or select "NO" if not, using , then press - The target color data nos. next to that of the deleted target color data will scroll up automatically. - ALL DELETE: Deletes all the target color data currently set in the instrument. All the target color data will be deleted without a confirmation message.

Note

If the target mode is "linked to each data.", "T--" is displayed for target color number if the target color linked at the time of measurement is deleted, and the color difference for that data cannot be displayed.

Setting Color Difference Tolerances

This instrument allows you to set tolerances for the measured color difference, to make pass/fail judgment. Pass/fail judgment is made based on two types of tolerances: box tolerances and elliptical tolerances. Prior to start of measurement, tolerances must be set.

Memo

- Two types of tolerances are available (box tolerances and elliptical tolerances). With this instrument, either box or elliptical tolerances can be set for each target color. However, the following restrictions apply to the tolerance type that can be set, depending on the selected color space. - In the case of "MUNSELL" and "DENSITY" as the Color Space, neither box nor elliptical tolerances can be set. - In the case of "WI", "YI", "ISO BRIGHTNESS" and "WI/Tint" as the Color Space, only box tolerances can be set. - In the case of "Spect. Graph" as the Display Mode, neither box nor elliptical tolerance can be set.

Note

Once tolerances are set, the tolerance type cannot be changed. To change the tolerance type, the currently set tolerances must be cleared.

Box Tolerance

If the measured color difference is outside the specified tolerances set for the target color, it will be highlighted to indicate that the pass/fail judgment result is FAIL. Both + and - box tolerances can be set for each target color.

Note

Target colors must be set before setting tolerances.

Measurement Results for "linked to each data."

This instrument can set multiple target color data numbers and select one of those for displaying the results for the color difference. It can also easily switch the selected target color number using the navigation wheel. The "defined in COND." target mode can use these functions to calculate multiple color differences for measurement data, and make pass/fail judgments based on this. However, the pass/fail judgment is based on a standard color difference setting for the selected target color data number and the color difference. The differences between the target color data and the color difference is not always standard. The other target mode supported by this instrument, "linked to each data," can store the target color data number with the selected measurement data and display the results using the associated target color data number. In addition to absolute values, it can also be used for general color differences. This section describes how the results are affected when using "linked to each data." target mode and the specified target color data has been changed or deleted. It also compares the difference to the results displayed for "defined in COND." target mode.

When the Color Difference Target Data No. has Been Changed

When "T" is selected in the measurement results screen, the target color screen will be changed to the currently selected number to be used for next measurement. The navigation wheel can also be used in this screen to recall a target color number that has been stored in the instrument's memory. If "BREAK" is selected in the target color data screen, you can revert to the originally selected target color number. For details, see "Switching between the Measured Data screen and the screen" on page E-49. 

When the Target Color Data No. has Been Deleted

If the target color data for a number is deleted, the target color for data to which that number was associated is set to that of the next highest number. The target color number is reset to that of the number for which there is a target color data number. With "linked to each data." target-mode, the measured data is saved with target color number that was specified for it at the time of measurement. If the number for the target color that was set at the time of measurement is deleted, the link between the data and target color data number is cut when the number is deleted. The measurement data is saved with information that states that there is no target color for that data, "T---" is displayed for the target color, and "----" for the color difference and pass/fail judgment. In addition, no points appear on the graph. With "defined in COND." the color difference and pass/fail judgments for the reset target color data and its data are recalculated based on the associated color difference.   If a number for target color data is deleted, the target color is set to the next target color, but set as the target color of the deleted number. * In the example above, target color T2 has been set to number T1.

Other Functions

Measuring the Average

When taking measurements or setting target colors, more accurate data can be obtained if the averaging function is used. The following two averaging functions are available. - Manual Averaging: When the color of the specimen is not uniform, measurements are performed at different positions on the specimen and then the average of the measured reflectance data is calculated. This gives the average data of the entire specimen. - Auto Averaging: Specified number of measurement are repeated at the same position on the specimen and then the average of the measured spectral reflectance data is calculated. This will improve the accuracy of the measured data. These two functions can be used in combination. In this case, it is necessary to make settings for both auto and manual averaging. For details, refer to "Setting a Measurement Condition" (from page E-34).

Note

For average measurement, the average of the measured spectral reflectance data is calculated first, then colorimetric data is calculated based on that calculated average. Thus, the result may not match the average of colorimetric data.

Manual Averaging

This method is used when the color of the specimen is not uniform. Measurements are performed at different positions on the specimen and then the average of the measured reflectance data is calculated, to obtain the average data of the entire specimen. Set the number of measurements to be performed and the standard deviation, and then start measurement.

Note

Before starting manual averaging, make sure that the number of measurements to be performed and standard deviation are set. For details, refer to "Setting an Measurement Condition" (from page E-34).

[Setting Procedure]

This operation can be started from a screen in which "BREAK" is displayed.

1 Make sure that "BREAK" is highlighted, then press

Turn to select "BREAK", if it is not highlighted.  - Example when "COND1" is selected.

2 Place the specimen measuring port to the specimen to be measured, and then press (MEAS. button).

If 2 is set for "MANUAL AVG. TIMES" or if 3 or a higher value is set and the standard deviation is not below the specified one, place the specimen measuring port to the next place and then press (MEAS. button).   - The number of completed measurements including the one currently in progress and standard deviation will be displayed during measurement. When the specified number of measurements has been completed or the standard deviation drops below the specified one, the averaging result will be displayed on the LCD. 

Memo

- To exit manual averaging and display the results before the specified number of measurements is completed or before the specified standard deviation is reached, press - If does not appear due to the auto power save function, this may be due the fact that it can take time to start measurement after is pressed.

Auto Averaging

Measurement is repeated the specified number of times in the same position on the specimen and then the average of the measured reflectance data is calculated. This will improve the accuracy of the measured data. Set the number of measurements to be performed and the standard deviation, and then start measurement.

Note

Before starting auto averaging, make sure that the number of measurements to be performed is set. For details, refer to "Setting a Measurement Condition" (from page E-34).

[Setting Procedure]

This operation must be started from a screen in which "BREAK" is displayed.

1 Make sure that "BREAK" is highlighted, then press

Turn to select "BREAK", if it is not highlighted.  Example when "COND1" is selected

2 Place the spimen measuring port to the specimen, and then press (MEAS. button).

 - Take care to keep the instrument still during measurement. The number of lamp flashing will be highlighted during auto averaging.  When the specified number of measurements has been completed, the averaging result will be displayed on the LCD. 

Memo

If does not appear due to the auto power save function, this may be due the fact that it can take time to start measurement after is pressed.

Pass/Fail Judgment for Color Difference

This instrument allows you to set tolerances for the measured color difference, to make pass/fail judgment. Two kinds of pass/fail judgment methods are available. One is based on the specified box tolerances, and the other is based on the specified elliptical tolerances. In "linked to each data." mode, the number of the target color data selected at the time of measurement or the measured data are passed/failed based on the tolerances. If the target color data has been deleted, the color difference displayed for that color target and based on the tolerances for the color target cannot be performed. In addition, if other target color data is selected, recalculations and pass/fail judgments cannot take place.

Pass/Fail Judgment Based on Box Tolerances

If the measured color difference is outside the specified tolerances, it will be highlighted to indicate that the pass/fail judgment result is FAIL. Both + and - tolerances can be set for each target color. To perform pass/fail judgment based on the specified box tolerances, follow the procedure given below:  To use this function, make sure that the target color to be used is set.

[Setting Procedure]

screen 1 Turn to select "TARGET", then press  - "T* does not appear if "defined in COND." mode is selected. 2 Turn to select "▲▼", then press "△”will change to " "  3 Turn to select the desired target color no. (T*) , then press "▼▲" will return to "▲▶".  - Keeping held down to left or right will cause the target color No. to change continuously.

4 Turn to select "TOLERANCE", then press

The currently set tolerances will be displayed. 

5 If they are satisfactory, turn to select "BREAK", then press

The measurement screen will appear. 

6 Place the specimen measuring port to the specimen, and then press (MEAS. button).


Values for the items that have failed will be highlighted.  - “#####” will be displayed if the color difference data has two or more decimal places.

"FAIL" will be displayed and highlighted if any of the items has failed, and "PASS" will be displayed if all the items have passed.  - Here the judgment result is "PASS", and the results are displayed as shown above according to the conditions when the data was measured.  - Here the judgment result is "FAIL", and the results are displayed as shown above according to the conditions when the data was measured.

Memo

- If "PASS/FAIL" has been selected as the display mode, "PASS" will be displayed only when all the items have passed. - If "DIFF/ABS" has been selected as the display mode, the values for the items which have failed will be highlighted - If a color difference has not been set, when the target mode is "linked to each data", and the target color data number set at the time of measurement is deleted, "----" appears instead of "PASS/FAIL". - If does not appear due to the auto power save function, this may be due the fact that it can take time to start measurement after is pressed.

Pass/Fail Judgment Based on Elliptical Tolerances

This function is used to judge whether the measured color difference is within the elliptical tolerances specified for the target color. To perform pass/fail judgment based on the specified elliptical tolerances, follow the procedure given below:

Note

- To use this function, make sure that elliptical tolerances are set. - “PASS” or “FAIL” is displayed only if “PASS/FAIL” has been selected as the display mode.

Note

- The instrument and printer must be connected using a printer cable that is wired as shown in "Printer Cable Wiring Diagram" (page E-92). - Before connecting, make sure that the power to both the instrument and printer is turned OFF.

[Procedure]

This operation must be started from the screen. 1. Turn to select “ ”, then press "△”will change to“▼▲”.  2. Turn to select the color difference target data to be printed, then press "▼▲" will return to "▲▶".  - Keeping held down to left or right will cause the color difference target data No. (T*) to change continuously. 3. Turn to select "P", then press 

Memo

- If "SPECT.CHAIN" has been selected as the display mode, spectral reflectance data will be printed. - If a mode other than "SPECT.GRAPH" has been selected as the display mode, only colorimetric value data will be printed.

TASK Mode

What is TASK Mode?

TASK mode is the function that allows you to perform measurement according to the messages displayed in the LCD indicating the measurement procedure. The messages can be created by using the previously used software SpectraMagic (Ver. 3.2 or higher; except for Ver. 3.5) with your PC and downloading it as a TASK. Up to ten steps can be set for each task, and up to six tasks can be downloaded to the instrument. After measurements are taken, the measured data can be sent to SpectraMagic (Ver.3.2 or higher; except for Ver.3.5) for statistical color control.

Note

- It is not possible to create a task using the instrument alone. - TASK mode cannot be selected if no task has been downloaded. To use TASK mode, a task must be downloaded to the instrument in advance. - When downloading a task, if the task has the same name (No.) as that of a task already existing in the instrument, the existing task will be overwritten by the downloaded task, if no measured data is contained.

Performing Measurement in TASK Mode

The following two measurement methods are available for TASK mode. One is to perform manual average conducted by messages displaying the result after each measurement using a single target color. The measurement result obtained by this method will be the average of the measured data obtained by each measurement. The other is to perform measurements in a series using the specific target color for each measurement and obtain the measurement result for each measurement.

Note

- To perform measurement in TASK mode, a task must be downloaded to the instrument in advance. A task can be downloaded using the optional, previously used Color Data Software "SpectraMagic" (Ver. 3.2 or higher; except for Ver.3.5) from the PC connected to the instrument. - TASK mode doesn't allow you to set measurement conditions and select target colors using the instrument alone. The measurement condition for TASK mode and target color to be used for measurement must be set using SpectraMagic and downloaded in the TASK together with the task. Measurement of the target color can also be performed by the instrument alone. - Prior to start of measurement, be sure to perform white calibration. If necessary, perform zero calibration before white calibration.

Memo

If power is turned OFF during TASK mode, the screen for TASK mode (see step 4 on page E-100) will be displayed when power is turned ON next time. To perform measurement in TASK mode, follow the procedure given below.

Appendix

Principles of Measurement

Illuminating/Viewing System

The flow of measurement is shown below. This instrument utilizes the D/8 geometry conforming to CIE No.15, ISO 7724/1, ASTM E1164, DIN 5033 Tei17, and JIS Z8722-1982 (diffused illumination/8° viewing system) standards, and offers simultaneous SCI (specular component included) and SCE (specular component excluded) measurements. ① Illumination Light from xenon lamps diffuses in the integrating sphere and illuminates the specimen uniformly. ② Receiving a: Light reflected by the specimen is received. b: Light diffused in the integrating sphere is received. ③ Sensing Light is transmitted to the specimen-measuring and illumination-monitoring optical system, where the light in the wavelength range of 360 to 740nm is divided into 10nm-pitch components and signal proportional to the light intensity of each component are output to the analog processing circuit. ① Light from xenon lamps diffuses on the inner surface of the integrating sphere and illuminates the specimen uniformly. ② a. The light reflected by the specimen surface at an angle of 8 degrees to the normal of the surface is received by the specimen-measuring optical system. b. The diffused light in the integrating sphere is received by the illumination-monitoring optical system and guided to the sensor. ③ The light reflected by the specimen surface and the diffused light are divided into each wavelength component by the specimen-measuring optical system and illumination-monitoring optical sensor, respectively, and then signal proportional to the light intensity of each component are output to the analog processing circuit. By using the outputs from the specimen-measuring optical system and the illumination-monitoring sensor for calculation, compensation for slight fluctuation in spectral characteristic and the intensity of the illumination light is performed. (Double-beam system)

Illumination Area and Measurement Area

The CM-2600d allows selection of either SAV (ø3 mm) or MAV (ø8 mm) measurement area according to the specimen and applications. A Target Mask (illumination area) suitable for the selected measurement area must be installed.

Note

With the CM-2500d, only MAV(0.8 mm) is available.

Target Mask

Since this instrument does not have automatic Target Mask matched to the selected measurement area, it must be attached correctly. Since the condition of the inner surface of the Target Masks affects measured values, do not touch the inner surface by hand, scratch it or allow it to get dirty.

Note

With the CM-2500d, it is not possible to exchange a Target Mask since only MAV(08mm) is available.

Measurement Area

The measurement area can be switched between SAV and MAV by sliding the measurement area selector provided on the side of the instrument.

Note

With the CM-2500d, no measurement area selector is provided.

Simultaneous SCI/SCE Measurement

The CM-2600d/2500d employs simultaneous SCI/SCE measurement method. With the conventional models, SCI (Specular Component Included) and SCE (Specular Component Excluded) need to be switched mechanically by opening/closing the optical trap provided inside the integrating sphere. This means mechanical switching has to be made each time the mode is switched from SCI to SCE or vice versa, and it is not possible to start measurement in the new mode until switching is complete. With the CM-2600d/2500d, both SCI and SCE data can be obtained simultaneously by calculating the data obtained by two illuminantations.

Simultaneous SCI/SCE Measurement Method

Two light sources ① and ② are located as shown in the figure, and light source ① flashes first. Light source ① is the diffused illumination type, and SCI measured data can be obtained as it flashes. Then, light source ② flashes next. Light source ② is provided for numeric control of the specular component. The data (i.e. amount of light reflected specularly from the surface of the specimen) obtained when this light source flashes and that obtained when light source ① flashed are used to calculate SCE data.  By carrying out the above measurement and calculation during a single measurement, both SCI and SCE data can be obtained simultaneously without mechanical switching that is required in the case of the conventional models.

UV Control

With the CM-2600d, two light sources, one contains UV (Ultraviolet) component and the other doesn't, flash sequentially and a desired illumination containing the specific UV intensity is virtually created by calculation based on the two measured numeric data sets. In case of conventional models with a single light source, the position of UV cutoff filter in the flux from the light source is mechanically adjusted to control the UV intensity. The adjustment of the filter position requires repeated operations. Since the UV control in CM-2600d is performed by the calculation based on the data measured using two light sources, it is completed in a instance and the deterioration of a fluorescent standard which often happens in conventional models due to the repeated illumination during adjustment is prevented.

Mechanism of UV Control

Two light sources ① (without UV cutoff filter) and ② (with a UV cutoff filter) are located as shown below. Light sources ① and ② flash sequentially within the measurement time of approximately 2 seconds. As a result, the spectral reflectance data with and without UV component can be obtained, based on which the calculation for UV intensity control is performed. These two spectral reflectance data are compared/merged to obtain the UV intensity correction data. 

Target Mode

Relation Between Measured Data and Target Color

- In "linked to each data." mode, there is specific target color data associated with the selected number of the target color data at the time of measurement. - In "defined in COND." mode, the target color data depends on the conditions. There is a unique link for the selected number of the target color data at the time of measurement, however, if the number of the target color is changed, the results are recalculated based on the new target color number.

Deleting a Color Difference Target Data

If target color data is deleted, the numbers for other target color data is renumbered. For example, if target color data numbers T1 to T10 have been set and T2 is deleted, the date that was numbered T3 is renumbered T2 and T4 becomes T3, and so on for the other numbers. - In "linked to each data." mode, if the target color data number selected at the time of measurement is modified (deleted or change), then the link to that target color data is cut. The target color data associated with that measurement data is lost forever, and is not recalculated using other target color data. The color difference display based on the target color data does not occur and pass/fail judgments are not performed, and “----” is displayed for the color difference. “T---” is displayed for the target color data number. - In "defined in COND." mode, there is a link to the target color data number selected at the time of measurement. For example, if the current target color set for T2 was set as T3 at the time of measurement, and even if the actual target color data used at the time of measurement is deleted, the results are calculated and displayed based on the new T2 target color.

Notes on Changing the Target Mode

This instrument comes with two user selectable target modes, "linked to each data." and "defined in COND."

Note

- Once the target mode is changed, previous data will be cleared. It is recommended that you save previous data into other storage media in advance by using the Color Data Software that is optionally available. - For the target mode changing procedure, please read "Selecting the Target Mode" on page E-28.
