Product Description
200 colorimeter is researched and developed in accordance with CIE (International
Commission on Illumination) and CNS (China National Standards). 200
colorimeter is a high precise colorimeter with simple user interface and stable
performance. It can be powered by both Li-ion battery and external DC power
supply.
White and black calibration is not required for 200 colorimeter which greatly simplifies
the measuring steps.
200 colorimeter adopts illumination locating which brings out more precise and quicker
locating.
200 adopts complex advanced algorithms which make measurement performance
more stable, more accurate and more compatible.
Cautions
● This colorimeter is a precise measuring instrument. Please avoid dramatic changes of
external environment when measuring. These changes, including the flicker of
surrounding light, the rapid change of temperature, will affect the measuring accuracy.
● Keep the instrument balanceable; make sure the measuring aperture cling to the test
sample, and no shaking or shifting when measuring. Please prevent the colorimeter
from fierce collision or crash.
● This instrument is not waterproof. Do not use it in high humidity environment or in water.
● Keep the colorimeter clean. Avoid dust, powder or solid particles entering the measuring
aperture and the instrument.
● Replace the white calibration cover and put the colorimeter into instrument cabinet when
not in use.
● Please take out the battery to prevent the colorimeter from damage if you don’t use it for
a long time.
● Please keep the colorimeter in a cool dry place.
● Any unauthorized changes to the colorimeter are not permitted, or it will affect the
measuring accuracy, even cause irreversible damage.

IV. 200 Colorimeter Operating Instruction
（I）Turning Power On
1. Preparations Before Power On
a) Check whether there is battery powered or external power supply.
b) Make sure the white calibration cover is connected to the instrument and well
installed. If it is loose or the white calibration cover isn’t well installed, you must
put the cover on and be sure it is connected to the instrument tightly.
2. Turning Power On
Press the power switch on the back side of the instrument, the LCD screen will
display MRC logo. After a few seconds, it will enter Standard Measurement
interface automatically, and the default display is L*a*b*C*H.
3. White Calibration and Black Calibration
Note: White and black calibration is not required for 200 colorimeter.
Only when the measured data are not accurate enough, manual calibration
is needed.
After turning on 200 colorimeter, press “Menu” to enter the main menu, as
shown in Figure 5. Select “Calibrate” to enter White and Black Calibration
interface, as shown in Figure 6.
Be sure the white calibration cover is well installed. Selecting “White Calibration”
and press “Enter” button, the instrument will prompt you to place the white
calibration plate. Then press “Enter” or “Testing” key to start white calibration.
Be sure the white calibration cover is removed. Select “Black Calibration” and
press “Enter”. The instrument will prompt you to direct the measuring aperture to
the air. Press “Enter” again or press “Testing” key to start black calibration.
Note: When starting black calibration, direct the measuring port to the air.
Be sure the black calibration is performing in a dark, no bright light source
environment. Keep the measuring port more than 3m away from any
reflective items (hands, desks, walls etc.).
By then, manual white calibration and black calibration are completed.
