8 .5 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 . 1 Calibrating and Adjusting Device with
isoCAL Function (Only Model I-1x)
Triggers for the automatic start of the isoCAL function
are:
− The ambient temperature has changed since the last
adjustment process .
− The interval time has been exceeded .
− If this relates to a conformity-assessed model: The

− The device is not in the main menu .
− The load on the weighing pan remains unchanged
for 2 minutes.
− The load on the weighing pan amounts to no more
than 2% of the maximum load .
− The device does not register an input for 2 minutes .
