• Insert three AAA/Micro batteries into the battery compartment paying attention to the correct polarity (observe positive/+ and negative/-).
• Put back the battery cover and tighten it again.
• The battery must be replaced if the display contrast fades or the device cannot be switched on any longer. Additionally, a battery symbol indicates the state of the batteries or rechargeable batteries in form of a bar graph.

Operation

a) Switching on/off

• Shortly press the "O button (6) to switch the luxmeter on or off.
• If no button is pressed, the luxmeter switches off automatically after 3 - 5 minutes to save power.

The automatic switch-off function can be deactivated. Switch on the luxmeter by pressing the "C button (6) briefly.

Then, press and hold the button (6) for 1 second and the symbol "as disappeared. If you wish to reactivate the switch-off function, hold the button (6) again for 1 second and the symbol appears on the display again.

Be sure to always put the protective cap (11) on to the sensor (10) when no measurements are performed.

b) Measuring the illuminance level (Lux/Fc)

• Switch the luxmeter on.
• Remove the protective cap (11) from the sensor (10).
• Hold the sensor housing with the sensor in a way that the light to be measured falls on the sensor as vertically as possible.
• Press the "LX/FC/CD" button (3) shortly in order to switch between the measurement unit "Lux" and "Fc" ("Lux" = illuminance level lx, "Fc" = "footcandle"), depending on which unit you need (the unit "Fc" is commonly used in the USA).

The measured value shown on the display changes according to the incidence of light on the sensor.

If the values are in increased, the value-display will be extended to the fifth and sixth digit (see the example in the picture on the right, the value = 399900 Lux).

In this the single and ten digit are presented with smaller numbers, by increased measured values the larger number is the important one and the numbers in the one or ten digit place represent the tolerance/deviation.

When pressing the "LX/FC/CD" button (3) for more than 1 second you get to the measurement mode for the luminous intensity (unit "cd", Candela), see next section c).

Press the "HOLD L.S." button (9) shortly to "freeze" the displayed measured value (data hold function). "HOLD" will be shown in the upper right corner of the display.
Press the "HOLD L.S." button (9) again to exit the mode.
- When the measurement process is completed, put the protective cap (11) on to the sensor (10) auf and switch off the luxmeter.

c) Measuring the lumionous intensity (cd)

• Switch the luxmeter on.
• Remove the protective cap (11) from the sensor (10).
• Press and hold the key "LX/FC/CD" button (3) for 1 second. The measurement display disappears, the upper right corner of the display will show "CD" and the unit "m" (meter) respectively "ft" (feet = 30,48 cm) will flash in the lower right corner of the display.
• Select the desired unit using the "▲" (4) or the "▼" (8) button.
• Briefly press the "LX/FC/CD" button (3). Now, the distance value (the distance between the centre of the light source and the sensor) will flash on the display.

The pre-set distance value is "1 m" resp. "3,28 ft".

• Set the distance using the "▲" (4) or the "▼" (8) button. For quick adjustment, hold the corresponding button for a little longer. The adjustable range for the distance value is between 0.01 and 30.47 m resp. 0.01 and 99.99 ft.
• Briefly press the "LX/FC/CD" button (3).
  The measured value is shown on the display.

The luminous intensity can be calculated as follows:

Luminous intensity (cd) = illuminance level (lux) x distance

d) Data hold function

During the measurement process, the measured value shown on the display changes according to the incidence of light on the sensor (10).

In order to better read the measured value (or to be able to save it), you have the possibility to activate the data hold function. To do so, briefly press the "HOLD L.S." button (9) during the measurement. The measured value displayed "freezes" and will not change any more so that it is easier to read or save it.

"HOLD" will be shown in the upper right corner of the display.

Press the "HOLD L.S." button (9) again to exit the mode. The "HOLD" symbol disappears.

e) Calibrating function

• Switch the luxmeter on.
• Put the protective cap (11) on to the sensor (10).
• Briefly press the "ZERO" button (5).
• "AdJ" will be shown on the display for a few seconds. The luxmeter will be calibrated and the display will be reset to 0.00.

If "CAP" appears on the display, the protective cap is not mounted completely or correctly and the sensor measures too much light. If so, execute the calibration process in a slightly darker environment.

If "CAP" does not disappear from the display, briefly switch off the luxmeter and switch it on again.

f) Displaying maximum, average and minimum value

This is only possible during the measurement process of the illuminance level (Lux/Fc), but not during the measurement of the luminous intensity (cd).
- Press the "▲" button repeatedly during the measurement in order to switch between the following operation modes (the respective operation mode will be displayed above the measured value):

"MAX" The luxmeter will only show the highest measured value.

"AVG The luxmeter will continuously calculate and display the average value.

"MIN The luxmeter will only show the lowest measured value.

• To exit the current operation mode, hold down the "▲" button (4) for about one second. The operation mode ("MAX", "AVG" or "MIN") will no longer be shown on the display.

g) Selecting/changing/saving correction parameters

Light sources have different colour spectra. In order to be able to compare the measured light intensity, different sensors would be required.

With the luxmeter MS-200 this is not necessary since the light intensity can automatically be corrected and displayed using an adjustable correction factor (9 different memories available).

Examples using the correction factor:

Light source Correction factor
Incandescent bulbs/daylight 1.000
Daylight white LEDs 0.990
Red LEDs	0.516
Amber yellow LEDs	0.815
Green LEDs	1.216
Blue LEDs	1.475
Purple LEDs	1.148
Neon tubes white	0.870
Neon tubes blue	1.286
Neon tubes green	1.167
Neon tubes red	0.671

The measured value displayed when the correction factor is set to "1.000" refers to a standard incandescent bulb with a colour temperature of 2856 K (Illuminant A).

More information on this can be found in the corresponding technical literature or on the Internet.

The luxmeter has 9 memories (L1...L9) for correction parameters ("Light Source" is shown in the bottom line of the display incl. the currently active correction parameter).

If necessary, the measured value shown on the display can be corrected automatically.

Example:

Measured value: 2000 lux, correction factor 1.200

The display shows: 2400 lux (2000 x 1.200 = 2400)

Always ensure that the correct correction parameter is selected during the measurement process as otherwise the displayed value may be wrong.

If you don't want the value to be corrected, select correction parameter *1.000 (set the correction parameter ^ 一 1 . 0 0 0 ^ 一 in one of the 9 memories and select the respective memory for the display of the uncorrected measured value).

Selecting the memory for the correction parameter

This is only possible during the measurement process of the illuminance level (Lux/ Fc), but not during the measurement of the luminous intensity (cd).

In this case, select the measuring mode for the illuminance level first and then select a memory for the correction factor. Then, proceed to the measurement of the luminous intensity. The previously set correction factor will also be used during the measurement process of the luminous intensity.

• Press and hold the "HOLD L.S." button (9) for 1 second and the numbers (1...9) on the bottom of the display will flash.
• Select the desired memory using the "▲" (4) or the "▼" (8) button.
• Press and hold the "HOLD L.S." button (9) again for one second and the display will stop flashing and the memory has been selected successfully.

Changing/saving correction parameters

• Press and hold the "HOLD L.S." button (9) for 1 second and the numbers (1...9) on the bottom of the display will flash.
• Select the desired memory using the "▲" (4) or the "▼" (8) button.
• Briefly press the "HOLD L.S." (9) button and the correction parameter display flashes.
• Set the correction parameter using the "▲" (4) or the "▼" (8) button. For a quick adjustment, hold the corresponding button for a longer period of time.
• Press and hold the "HOLD L.S." button (9) for one second and the correction value will be saved and the display stops flashing.

h) Saving/displaying/deleting measured values

Saving the measured value

The luxmeter has over 99 memories (01...99) for the measured values of the illuminance level (lux/fc). When saving, not only the measured value but also the unit set during saving (lux or fc) will be stored in the memory.

Measured values of the luminous intensity can not be saved.

To save a measured value, briefly press the "MEM READ" (2) button. The upper left corner of the display will briefly show "M" and the storage number (e.g. "No. 01").

Displaying the measured value

In order to display one of the 99 stored measured values, proceed as follows:

• Press and hold the "MEM READ" button (2) for 1 second and the upper left corner of the display will show "R" and the last saved measured value (and the storage number) will be shown.
• Select the desired memory using the "▲" (4) or the "▼" (8) button. For quick adjustment, hold the corresponding button for a little longer.
• To exit the die saved measured value mode press and hold the "MEM READ" button (2) again for 1 second. "R" and the storage number will disappear from the display.

Deleting Measured Values

Deleting a single memory is not possible. you can only delete all memories at one time.

• Shortly press the "按钮 (6) to switch the luxmeter off.
• Press and hold the " button (6) and the "MEM READ" button (2) at the same time. "CLR" appears on the display.

When "CLR" disappears from the display, all stored measured values have been deleted. Now release both buttons.
