"Calibration/Adjustment" Function via RS-232 Interface
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 a suitable level within maximum permissible error limits.
Characteristics
The adjustment procedure should only be started when
– The weigh cell is not loaded
– The weigh cell is tared
– The weighing signal is stable
– The sensitivity of the balance can be corrected by max. 2%.
If these criteria are not met, error message "Err 02" appears.
Error message "Err02":
– Note ambient conditions
– Weigh cell needs stability
– I f necessary, change the pre-configured balance parameters:
Select Ambient conditions menu item 1.1.1.4 (very unstable) or execute interface
command ESC N
Adjustment can be made using different weight units:
CAL.Unit > Gram, Kilogr.
