To level the device: Bring the air bubble of the level
t
indicator into the middle of the circular marking. To
do so, turn the leveling feet to the left or right.

Overview of Calibration and
Adjustment
During calibration, a calibration weight is used to
determine the deviation of the displayed value from the
actual value. The subsequent adjustment eliminates this
deviation.
We recommend regular calibration and adjustment:
— Daily, every time the device is switched on
— After every leveling
— After changing the ambient conditions (temperature,
humidity, or air pressure)
— After setting the device up at a new installation site
8.5

the Device Internally
(Only Model I-2x)
Requirements
— The weighing pan is unloaded.
— The operating display shows a stable weight value.
— The internal calibration and adjustment function is
set (see Chapter "7.2.1 Setting Internal Calibration
and Adjustment (Only Model I-2x)", page 16).

t
ing feet, until they touch
the setup surface.
