Calibration and Adjustment
Purpose
Calibration is the determination of any
difference between the measured value
displayed and the true weight (mass) of
a sample. Adjustment is the correction
of this difference, or its reduction to
an allowable level within maximum
permissible error limits.
Features
Calibration | adjustment can be
performed only when
– there is no load on the balance
– the balance is tared
– the internal signal is stable
– the weight displayed for the sample on
the balance must not differ from the
nominal weight by more than 2%.
If these conditions are not met, an error
message is displayed “Err 02".
Following calibration | adjustment,
the application program is cleared.
Internal Calibration | Adjustment
