6 On/off
To turn on the meter, press the on/off key. To turn off the meter, press and hold the on/off key
until “OFF“ is displayed.
7 Automatic Power Off
The gloss meter has an automatic power off function to save battery power. If no key is pressed
for 10 minutes when a single measurement is made, the meter will turn off automatically. When
a continuous measurement is made, the meter will power off automatically after an hour. This
function cannot be deactivated in measuring mode.
8 Measurement
The gloss meter hast wo measuring functions:
In single measuring mode, the user can press the MEAS key to make a measurement. will
be displayed during a measurement. The reading will be saved directly after a measurement.
In continuous measuring mode, the meter automatically makes continuous measurements
without requiring the user to make any entries. A measurement is made approx. every three
seconds. The readings are saved continuously.
To switch between these measuring functions, press and hold the on/off key until “SC” is
displayed after “OFF” was shown.
To change the measuring angle, press the ANGLE key.
9 Calibration
The gloss meter should be calibrated regularly. To calibrate the meter, place it onto the calibration
standard. Now make one measurement per angle and compare the readings to the values on the
reference.
If one reading is outside the parameters, you can automatically set the value for this angle by
pressing the CAL key while the meter is still on the reference.
10 New calibration standard
If you want to use a new calibration standard, this standard must first be added. To add the
standard, press and hold the on/off key (while the meter is on) until “CAL” appears on the display
(after ”OFF“ and ”SC“). Then press the CAL key. “CAL” will be displayed, followed by the angle
and the pre-set value. You can now change the reference value with the arrow keys. With the
ANGLE key, you can select the next measuring angle. After setting the reference values for all
measuring angles, press the ANGLE key to confirm the settings and return to measuring mode.

11 Saving/viewing/deleting measured data
This gloss meter has two functions which can be seen on the display.
The meter is in measuring mode
The meter is in memory readout mode
In measuring mode, each reding will be saved. A measurement is made as soon as the measuring
icon is displayed. A maximum of 254 values can be saved. When the memory is full, the
oldest memory item will be replaced.
To enter memory readout mode, press the RD key. The display will switch from “M“ to “R“. Use
the arrow keys to choose the saved reading you want to view.
With the DEL key, you can delete a single reading.
To return to measuring mode, press the MEAS key. The display will switch from “R“ to “M”.
To delete the complete memory at a time, press and hold the DEL key for three seconds in
measuring mode.
Note: If you try to enter memory readout mode when no measuring data are available, the display
will show “Err1“. Memory readout mode can only be opened if data have been saved.
12 Recharging the battery
To make sure you can still use the meter, it should be recharged when the battery icon
appears in the display. To charge the meter, use the charger that comes with it.
If the rechargeable battery needs to be replaced, please contact PCE Instruments.
13 What to bear in mind before and during a measurement
Before a measurement, make sure that no external light enters the measuring chamber as this
can affect the readings. When there are considerable temperature fluctuations, make sure the
meter becomes acclimatised to the new environmental conditions. Then re-calibrate the meter
before making a measurement. If the meter is used for a long period of time such as more than
an hour, regular calibrations must be made. Make sure to store the calibration reference safely
everytime it is removed.

15 Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the European
Parliament applies. Due to the contained pollutants, batteries must not be disposed of as
household waste. They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either reuse them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance
with your local waste regulations.
