3. Calibration
If the meter gets powered on in calibration holder, it will enter the calibration interface. The user can
perform the calibration operation according to the prompts, the instrument will enter measurement interface
after the calibration. If it is not powered on in the calibration holder, it will skip the calibration and enter the
measurement interface directly.
If it prompts that the calibration failed, the reasons may include:
 If the standard is not clean, please clean the standard with special lens cloth before placing the meter
into calibration holder.
 If the meter is not clung to the calibration holder, please re-place into calibration holder.
 If there is a significant change in the ambient temperature, restart the device for measurement after
the temperature of the instrument is close to the ambient temperature and it is confirmed that there is
no condensation on the lens in the test port and the standard of the base
 If the light source cannot work normally due to attenuation, the device needs to be sent back to the
factory for inspection and maintenance
When the instrument prompts "Calibration failed”, long press the button can skip the calibration.
4. Measurement
(1) Normal Mode
If the instrument is set to normal mode, remove the calibration holder after calibration, place the measuring
port on the surface of the object to measure, the instrument will display the measured value instantly. Short
press the button, the lower left corner of the interface displays the "HOLD" symbol, and the measurement

data is held on the display. To measure again, press the button to cancel the "HOLD" state and return to
the "Measuring" state.
(2) QC Mode
If the instrument is set to QC mode, remove the calibration holder after calibration, place the measuring
port of the instrument on the surface of the object to measure, short press the button to measure, the
instrument will judge whether the measured value is qualified. The upper and lower limits could be set by
PC software. For specific operations, please refer to the "Gloss Meter Software Operation Manual".
V. PC Software
Connect the instrument to PC software via USB cable to perform functions of online measurement, change
calibration values, parameter setting, test report generation and printing. For specific operations, please
refer to "Gloss Meter Software Operation Manual".

VI. Precautions
1. The temperature compensation function guarantees long-term calibration stability, it is recommended
to calibrate once a week. If the environmental temperature changes significantly, please recalibrate
it.
2. The measuring port of the instrument shall be attached to the surface of the object to avoid leakage
of external light.
3. Please save the calibration holder in a clean place after the meter is removed, so as to prevent the
standard from contamination.
4. Do not insert any object into the instrument for any reason, as it will damage it and influence the
measuring accuracy as well as operation safety.
5. The instrument and calibration standard should be cleaned before storage and usage, and please
use clean special lens cloth to remove contaminants. As the surface of the standard is very precise,
make sure there are no fine particles on the lens cloth to avoid damage of the standard.
6. If there are multiple meters, put the meter on the calibration holder corresponding to the serial
number of the meter for calibration.
7. When the battery of the instrument is out of power, it should be charged in time.
