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
