Leveling the Balance
(only for models BBL31, BBL32, BBL42 or BBL52)
Level the balance any time you
set it up in a new location.
Use only the 2 front feet of the
balance for leveling.
§
Turn the 2 rear feet until they
are in position
(only on model BBL52)
§
Turn the 2 front feet as shown
here in the illustration until the
air bubble is centered in the
level indicator
> In most cases this will require
several adjustment steps
Anti-theft Locking Device
To protect against theft, use the
mounting lug on the rear panel of
the balance.
§
Secure the balance at the
place of installation,
for example with a chain
or a lock

Calibration/Adjustment*
Always calibrate/adjust the balance after setting it up in
a new location.
Available Features
Calibration/adjustment can only be performed when
– there is no load on the balance,
– the balance is tared, and
– the internal signal is stable.
If these conditions are not met, an error message
is displayed. Otherwise, the weight required for calibration/
adjustment is displayed.
Calibration/adjustment can be performed with any of three
weight units: g, kg
1 ), or lb (menu code

* “Calibration” technically means to determine the difference between the
balance readout and the actual weight on the pan to determine the accuracy.
Adjustment means to bring a balance into the state of accuracy required for
its use. Therefore, “calibration,” as used in this manual, actually means
“adjustment.”
