7.Power ON / OFF
Press the key to power on the
meter. To turn it off, just press
this key again. This meter
is powered with 4 x1.5vAAA dry cell
batteries. To install or replace the
batteries, just remove the battery
cover and Insert the new cells in the
battery cartridge. Pay attention to
the battery pole.
8.Calibration:
Lay the main unit into the holder
with calibration standard of high
gloss black tile. Take a reading
by pressing the MEAS key.
Compare the measured value with
the value marked on the tile. If it
matches the value on the tile holder,
the instrument is within calibration
and ready for use. If the measured
value
does not match the assigned value,
just press the CAL key.
It is n ecessary to inspect t he
condition of the calibration tile and
instrument optics before each
calibration. Any dust or debris on
the optic should be blown from the
lenses using dry clean air, the
optics must not be touched. If there
are any permanent marks or
scratches on th e lense s , t h e
instrument is no longer suitable for
measuring and should be returned
to an authorized service center.
The calibration tile must be
perfectly clean from smears and
scratches before attempting
calibration. Fingerprints and dust
can be removed with the supplied
optic cleaning cloth.

9.Measurement
Remove the holder an d la y th e
Measurement Aperture just
against the position that you want
to measure. Take a
measurement by pressing the
MEAS key . The reading on the
Display Screen within 2
seconds is the gloss value of
that position. Meanwhile the
result is stored into
memory automatically.
When the instrument is placed on a
sample the aperture is hidden, the
centre of the measurement area can
be pinpointed by the intersection
of the arrows marked on the front
of the instrument case with those on
the side.
10.Data Memorizing
When taking measurements, all
values will be stored automatically
in memory and the number of
stored reading is accordingly
increased by
10.1 The gloss meter can store up to
2 5 4 g r o u p s o f d a t a w i t h
measurement conditions. If the
memory is full, the tester will auto
save the new reading and discard
the oldest one. That means the
tester only hold the last 254 groups
of data in memory.
11.Memory Recall
Under the measuring mode marked
by ‘M’ on the display , press the
key to enter into mode of viewing
stored values marked by ‘R’.
Press key or key to recall
stored values forwards and
backwards. To return to t h e
measurement state, just press any
key otherthan o r key .
12.Delete data in memory
In the measurement state marked by
‘M’ on the display , the new
reading can be deleted by pressing
key DEL , and the number of stored
reading is accordingly decreased by
1. To clear memory, just press and
hold DEL key for 3 seconds till the
number of stored reading becomes
000.
13.Download to PC
This meter can communicate with a
PC by optional USB or RS232C
cable and software. All the
memorized data can download to
your PC every time when in a
measurement state marked by
when you press RD / key to
enter the viewing memorized state.
14.Auto Power Off
The instrument features an auto
power off function designed to
conserve battery life. If the tool is
idle (neither measuring nor any key
operation) for 3 0 minutes, it will
turn itself off.
15.Battery Replacement
When the battery symbol appears on
the display, it is time to replace the
batteries. Slide the Battery Cover
away from the instrument and
remove the batteries. Install
batteries paying careful attention to
polarity.
Notes:
* The holder removed from the
main unit should be kept in a
safe and clean place to prevent
from damage or pollution.
* While measuring please keep
environment light from directly
irradiating into the measurement
aperture.
If necessary, especially under
strong light, shade it with a
piece of light-tight cloth.
* A big temperature difference
between environment and meter
would badly affect measuring
accuracy. In such a case, please
wait for a period of time till the
temperature get to a balance and
then calibrate the meter again.
* If measurement operation lasts a
long time., for example an hour
or more, it is necessary to
recalibrate the meter
