IV: Operation
1．Powering on
Under the status of powering off, press the button of "Power" to power
on the meter. Normally, the meter will successively enter into start
interface, warm-up interface, autodiagnosis interface, auto calibration
interface and measurement interface. The whole process will last
about 10 seconds. After entering into the measurement interface, the
users can make the measurement.
Start interface
Warm-up interface, warm-up process will last 5 seconds

Autodiagnosis interface. The meter must be power on in the
“Calibration Holder”, running autodiagnosis to timely find out the
system errors, improper operation and environmental changes.
Once the autodiagnosis result is normal, the system will display
"OK", with the meter entering into the auto calibration interface.
Autodiagnosis function to check whether the “calibration standard”
is clean. If the standard value of the “calibration standard” falls out
of qualified range, the meter will display “Please clean standard”.

Then, the followings should be carried out:
1.If the standard is not clean, please clean the standard with
special lens cloth, before placing the meter into the Calibration
Holder.
2.If the meter is not clung to the Calibration Holder, please re-place
into the Calibration Holder.
3.If a great change happens to the environmental temperature,
restart the meter for measurement, after confirming that the meter
temperature tends to be equal to the environmental temperature
and that lens in the measuring port and the standard on the
Calibration Holder are free from congealed hoarfrost.
After ruling out the above problems, place again the meter into the
Calibration Holder and the meter will run again the autodiagnosis. If
the troubles are removed, the meter will display “OK” and enter into
the auto calibration mode .
If the meter display “Please clean standard”. Also can enter into the
auto calibration mode manually by short press “Power “key.

2．Auto Calibration
If the meter starts in the Calibration Holder, it will enter into
calibration mode after autodiagnosis .If the autodiagonosis process
is still unfinished,short press “Power” key and the meter will enter
into auto calibration mode.
Before the number reaches 0, short press "Power" Key and
the meter will run auto calibration. After calibration, it will enter
into measurement mode,and the measuring value is the same
as that shown by the label on the right side of the meter.
If the no key pressed before the number reaches 0, the
meter will directly enter into the measuring status without
calibration operation.
If the system displays “Please call service” after calibration,the
reasons may include:
1) The standard is not clean. Please clean the standard before
calibrating.
2) The meter is not clung to the Calibration Holder. Please place

1-4-2019 Page 11 of 16
again the meter into the Calibration Holder before calibrating.
3) The light source is permanently damaged. Please send the
meter to the factory for maintenance.
Special attention:
1) Use of an unclean standard will seriously influence the
measuring accuracy. Please ensure the standard is clean and free
from scratches before calibrating. Use the special lens cloth (as
normal paper towels and cloths cannot be used to clean the
standard) provided by our company when you clean the standard.
Please use the cloth after cleaning, if the cloth is dirty.
2) If the meter does not start in the Calibration Holder, it will not run
autodiagnosis and auto calibration, but directly enter into
measurement status.
3)The standard value 94GU above is determined by the concrete
“standard”, different meters are equipped with different standard,
the specific standard value is shown by the label on the right side or
at the bottom of the meter.

3．Measurement
Put the meter on the surface of the object. The meter will
display the “Real Time value” directly.
Short press "Power" and record the current measured value.
Additional "1" will be automatically added to the measuring
times, which will return to 1 after reaching the counting times，
and maximum value, the minimum value, the average value and
the standard deviation will reset. Every time you press the
button, the meter will automatically count the maximum value,
the minimum value, the average value and the standard
deviation
The default counting times is 10 and the adjustable
range is 1-99. (See the User Manual of Gloss Meter for
counting times setting)
Long press “Power” key to clear all statistical data. The
system will restore the measuring times as 0

4．Powering off
The meter can be powered off in the following two ways:
In the power-on state, put the meter into the Calibration
Holder. The meter will power off after the “Time” reach zero.
The meter will automatically power off 3 minutes after the
users carry out no operation
Operation notes:
1) Please ensure that the calibration standard is clean and the meter is
pressed into the Calibration Holder before powering on, so that the
meter can run a successful autodiagnosis. If the meter starts in a place
other than the Calibration Holder, the meter will not run auto diagnosis
and auto calibration, but directly enter into the measurement mode.

2) Please save the Calibration Holder in a clean place after the meter
is removed, so as to prevent the standard from contaminating.
3) The meter has temperature compensation function which allows
calibration for a long period. Suggest to calibrate once for a week, and
recalibrate if the environmental temperature is greatly changed.
4 )The measuring port shall be attached to surface of the object to
avoid leakage of external light.
5) If a great change happens to the environmental temperature, restart
the meter for measurement, after confirming that the meter
temperature tends to be equal to the environmental temperature and
that lens in the measuring port and the standard on the Calibration
Holder are free from congealed hoarfrost.
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 not in use, place the meter on the Calibration Holder and
power it off.
V: Maintenance
1) Store the Calibration Holder in a clean place after removing
from the meter to prevent the standard from contaminating.
2)Before storing and using, clean the meter and the standard, and
use the clean special lens cloth to remove the contaminants. As
surface of the standard is very precise, make sure there are no

1-4-2019 Page 15 of 16
fine particles on the lens cloth to avoid damage of the standard.
3)Do not insert any object into the meter for cleaning, as it will
damage the meter and influence the measuring accuracy.
4)If the meter is not used over half a year, Please charge the
meter to avoid the battery is excessively discharged and
damaged.
5)Avoid to contact the corrosive agents and keep away from high
temperature and high humidity environment.
6) Put the meter in the specialized package after powering off and
keep it in a safe place.
7) The calibration period is suggested to be one year and the
company provides calibration service.
