Product Description
This instrument is researched and developed in accordance with CIE
(International Commission on Illumination) and CNS (China National
Standards). 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.

II. Interface Description
Figure 3 Interface Diagram
Interface Description
1. Power Switch: Push the switch to “1” means power-on to turn on the
colorimeter. Push the switch to “0” to cut power. Then the colorimeter is
turned off.
2. DC Interface: Connect with AC adapter. It is used to connect to external
power source. The specification of external power source is 5V=2A.
3. USB Interface / RS-232 Interface: This interface is a common interface.
The instrument judges the connection status automatically. USB interface
is used to transfer data to PC. Its baud rate is 115200bps. RS-232 interface
is used to connect to the printer.
Note: When connecting to external power s ource, please press the
power switch to start the instrument.

III. Battery Description and Installation
Battery Description
1. The Battery is Li-ion 3.7V = 0.5A. Its capacity is 3200mAh.
2. Please use original Li-ion battery. Do not use other batteries, or it will cause
irreversible damage.
3. Please take out the battery to prevent the colorimeter from the damage of
battery leakage if you don’t use it for a long time.
4. When charging the battery, the instrument must connect external power
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.
3. Put the battery cover on Li-ion battery, and then push it up.

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.
