Unpacking, installation and commissioning
5.1
Place of installation, place of use
The balance is constructed in such a way that reliable weighing
results can be achieved under normal application conditions.
By selecting the correct application location for your balance,
you will be able to work quickly and precisely.
Therefore please observe the following at the
results can be achieved under normal application conditions.
By selecting the correct application location for your balance,
you will be able to work quickly and precisely.
Therefore please observe the following at the
application
location:
• Avoid extreme heat as well as temperature fluctuation
• Avoid extreme heat as well as temperature fluctuation
caused by installing next to a radiator or in the direct
sunlight;
sunlight;
• Protect the balance against direct draughts due to open
windows and doors;
• Avoid jarring during weighing;
• Protect the balance against high humidity, vapours and
dust;
• Do not expose the device to extreme dampness for longer
periods of time. Inadmissible bedewing (condensation of air
moisture on the device) can occur if a cold device is taken
into a significantly warmer environment. In this case,
please acclimatise the device for approx. 2 hours at room
temperature after it has been disconnected from the bat-
terys.

terys.
• Avoid static charging of the material to be weighed, weigh-
ing container and windshield.
Major display deviations (incorrect weighing results) are possi-
ble if electromagnetic fields occur as well as due to static
charging and instable power supply. It is then necessary to
change the location.

Battery operation and change
Push off the battery cover on the back of the balance in the
direction of the arrow. Insert 9 V battery. Replace the battery
cover. When the batteries are exhausted the message "LO"
appears in the balance display. Press the OFF switch and
replace the batteries immediately. To preserve battery life the
balance switches off automatically after 4 minutes if no weigh-
ing has taken place. Deactivate this Auto-OFF function in the
menu as follows:#

Adjustment
As the acceleration value due to gravity is not the same at
every location on earth, each balance must be coordinated –
in compliance with the underlying physical weighing principle -
to the existing acceleration due to gravity at its place of location
( only if the balance has not already been adjusted to the loca-
tion in the factory). This adjustment process must be carried
out during the initial start-up, after change in location and varia-
tion of surrounding temperature. It is also recommendable to
adjust the balance periodically during weighing operation in
order to obtain exact measured values.

Adjusting
Using a precision weight, the accuracy of the balance can be
checked at any time and adjusted.
Adjustment procedure:
Check that the surrounding conditions are stable. A short
warm-up time of about 1 minutes are recommended for stabi-
lisation.
Press “UNIT” key approx. 3 seconds, ”CAL” and then the exact
weight of the adjusting weight will appear at the display.
Hang on the adjusting weight on the hook of the hanging scale.
“ F” will appear a short time later, and then turn off.
In case of an adjusting error or a wrong adjusting weight “ E”
appears in the display.
