3. Calibration
If the meter gets powered on in the 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 the calibration holder.
If the meter is not properly clicked to the calibration holder, please re-place into
calibration holder.
If the light source cannot work normally due to attenuation, the device should be
returned for repair.
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. A short press of the button and
the lower left corner of the interface displays the "HOLD" symbol, meanwhile 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.

Then place the measuring port of the instrument on the surface of the object to
measure. A short press of the button will measure and then the instrument will judge
whether the measured value is qualified. The upper and lower limits can be set
through the PC software.
V. PC Software
By connecting the instrument to the PC software via a USB cable, it can perform
functions such as online measurement, change of calibration values, parameter
settings, test report generation and printing.

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, 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. 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 you have multiple meters, put the meter on the calibration holder in
correspondence to its the serial number.
7. It is recommended that each meter should be calibrated at least once a year.
