4 Transport and storage
4.1 Testing upon acceptance
When receiving the appliance, please check packaging imme-
diately, and the appliance itself when unpacking for possible
visible damage.
4.2 Packaging
Keep all parts of the original packaging in case you need to
return the appliance.
Only use original packaging for returning.
5 Unpacking, Setup and Commissioning
5.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing
results are achieved in common conditions of use.
You will work accurately and fast, if you select the right location
for your balance.
Therefore, observe the following for the installation site:
• Avoid extreme heat as well as temperature fluctuation
caused by using next to a radiator or in the direct 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. Non-permitted condensation (condensa-
tion of air humidity on the appliance) may occur if a cold
appliance is taken to a considerably warmer environment.
In this case, acclimatize the appliance for ca. 2 hours at
room temperature.
• Avoid static charging of the material to be weighed, weigh-
ing container and windshield.
If electro-magnetic fields or static charge occur, or if the power
supply is unstable major deviations on the display (incorrect
weighing results) are possible. In that case, the location must
be changed.
5.2 Unpacking
Take the balance carefully out of the package and remove
the plastic cover.
5.3 Scope of delivery
• Suspended balance
• Batteries
• Operating Manual
5.4 Battery operation / Auto OFF function
Push out the battery cover on the balance backside. Insert 3
AAA batteries. Reinsert the battery cover. If the batteries are
empty, in the balance display appears “LO”. Press ON/OFF-
key and replace the batteries immediately. In order to save the
battery, the balance switches automatically off after 4 minutes
without weighing Deactivate this Auto-OFF function as follows:
Ö When the balance is switched off, press the HOLD-key
and keep it pressed
Ö Do not release the HOLD-key. Press also the
ON/OFF/TARE-key and keep it pressed
Ö Keep the ON/OFF/TARE-key pressed, however release
the HOLD-key
Ö Press HOLD-key anew
Ö Keep both keys pressed until in the display “tr” appears
Ö Release both keys. The balance is situated in the menu.
Ö Press the ON/OFF/TARE-key until „AF“ appears. Confirm
the selection of the Auto Off-function using the HOLD-key
Ö In the display appears the current setting „ON“ or „OFF“.
With help of the ON/OFF/TARE-key you can select be-
tween „ON“ or „OFF“. Confirm your selection with the
HOLD-key. After a short period the balance returns auto-
matically to weighing mode.
6 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. To receive accurate measur-
ing values it is also recommended to adjust the balance peri-
odically in weighing operation.
6.1 Adjustment
With an adjustment weight, the weighing accuracy can be
checked and re-adjusted at any time.
Procedure when adjusting:
Observe stable environmental conditions. A short warming up
time of ca. 1 minute is recommended for stabilization. Switch
on balance Press the Unit-key and keep it pressed (approx. 15
sec), in the display first appears shortly „CAL
“, after that there
appears the exact size of the adjustment weight. Suspend the
adjustment weight, a short time later appears „ F“, the balance
returns automatically to the weighing mode.
In case of an adjustment error or incorrect adjusting weight the
display will show "E"; repeat adjustment process.

7 Operation
7.1 Weighing
• The balance is switched on by pressing the „ON/OFF/TARE“
key.
• The balance displays „0.0“.
• Suspend material to be weighed.
• The weighing value appears in the display:
• If the material to be weighed is heavier than the weighing
range, the display will show "E" (=Overload).
• The balance is switched off by pressing the „ON/OFF“ key a
longer time.
