Product Description
It 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.
The instrument has following advantages:
●Can perform measurement at start-up. No need to calibrate each time which
simplify the operation.
●Adopt illuminating locating and precise cross locating to aim at the tested
object quickly.
●4mm measuring aperture for more measurement occasions.
●Save data automatically.
●The precise and stable hand-head structure to make the measurement
easier.
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.

source or USB cable to connect the PC. Meanwhile, push the switch to “1”,
and then the battery will be charging. If not charge the battery, then take out
the battery and connect external power source, the instrument still works
normally.
5. When charging the battery, dynamic battery icon will display on the top right
corner of measurement interface.
Battery Installation
1. When installing battery, be sure the power is cut off. (The switch is pushed
to “0”). Then remove the battery cover.
2. Insert the Li-ion battery into battery compartment and push it gently in right
direction.

IV. Changing Measuring Aperture
1. Measuring Aperture Installation
As shown in Figure 5, make the measuring aperture align at the installation
position of integrating sphere. Then gently turn it counterclockwise. When
hear slight “Da”, it means measuring aperture is buckled with integrating
sphere. Then the installation is finished.
2. Measuring Aperture Dismantlement
As shown in Figure 5, gently turn measuring aperture clockwise. When
hear slight “Da”, it means the measuring aperture is separated with the
buckling parts of integrating sphere. Then the measuring aperture is
dismantled.

Note: some models are only equipped with cross platform measuring
aperture.

V. Operating Instruction
(I)Turning On
1. Preparations Before Power On
Check whether there is battery powered or external power supply.
2. Turning On
Push the power switch to “1”, 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.
(II)Measurement
1. Measurement Locating
The instrument can locate by measurement facula. Enter “Standard
Measurement” or “Sample Measurement” interface, press the “Testing”
key and hold it. The facula will appear at the moment. You can observe
the matching status between the facula and the measured sample. At
the same time, hold the measuring aperture close to the measured
sample and adjust it. Then the alignment is achieved.
After the locating, release “Testing” button. The instrument will finish
sample testing in approx. 1 sec and display color parameters of the
measured sample.
2. Standard Measurement
Enter standard measurement to perform measurement, as shown in
Figure 6, align the measuring aperture to the sample, press “Testing”
button, the screen will display color data of this sample.

3. Sample Measurement
After completing standard measurement, press “Enter” button, the
instrument will enter “Sample Measurement” interface automatically, as
shown in Figure 7. Align the measuring aperture to the test sample to
perform sample measurement.

2. White and Black Calibration
Press “MENU ” to enter the main menu. Select “Calibrate” to enter
manual white calibration and black calibration interface, as shown in
Figure 13.
Select “White Calibration” and press “Enter” button; the interface will
prompt you to put away the white calibration cover. Turn the colorimeter
upside down and make the measuring aperture upwards, then put the
white calibration board in the center of the colorimeter and make sure it
is closed to measuring aperture. Re-press “Testing” key to perform
white calibration.
Next step is black calibration: remove white calibration board. Select
“Black Calibration” and press “Enter” button, the instrument will prompt
to direct the measuring aperture to the air (please refer to the “Notes”

Notes:
1. When performing black calibration, direct the measuring port to the
air. Be sure the black calibration is starting in a dark, no bright light
source environment. Keep the measuring port more than 1m away
from any reflective items (hands, desks, walls etc.).
2. No need to enforce black and white calibration. Once turning it on,
you can start the measurement. It is suggested to perform
calibration in following occasions: first use, great change of the
environment, long-term unused or inaccurate data.
3. Tolerance Setting
Select “Tolerance” in main menu to enter tolerance setting interface, as
shown in Figure 14. You can add or subtract the number in which the
cursor is positioned through “Up” and “Down” button. After setting the
number to the needed one, press “Enter” button, the cursor will jump to
the last number. When the cursor is in the last number, press “Enter”
button to save the settings and return to the main menu.
If you don’t want to set or modify the tolerance, you can press “Back”
button to return to the main menu.

The tolerance value is artificial. It is a standard value to judge whether the total
color difference ΔE is qualified or not according to the demand of color
management. If ΔE is smaller than tolerance value, then it is qualified. If ΔE is
bigger than tolerance value, then it is unqualified. As shown in Figure 14-1, the
ΔE in sample measurement interface is unqualified.
