F6 to start the internal span adjustment.
– The built-in calibration weight is applied automatically, the weight is
stored, and the deviation from the last span adjustment is displayed.
Note:
Depending on the menu code setting (under 1 10 X), either calibration/
adjustment is made automatically (code 1 10 1: calibrate, then auto-adjust),
or the deviation from the last linearization is displayed, but no adjustment is
made until you press a key (code 1 10 2: calibrate, then manual adjust).
– If the error exceeds the tolerance limits, press
F6F6
F6F6
F6 to make the correspond-
ing adjustment, or press

F1 to cancel the adjustment procedure.
– The balance then returns to the weighing mode.
External Span Adjustment
There are two ways to perform external span adjustment:
1. with the Sartorius service software (PSION Server or SARTOCAS Service
Software for PCs) - if the adjustment error is greater than ± 2%, or
2. with the balance in the service mode, as described in this manual.
External Span Adjustment with Manual Input of Weight Values
Note: You only need to input the calibration weight for span adjustment if:
1. the available weight is not sufficiently accurate (at least one digit
greater than the display accuracy), or
2. you are working with a weight other than the recommended weight
(e.g., with a heavier weight, close to the maximum capacity).
– Press e to turn on the balance.
– The balance performs a self-test.
– When 0.00 g is displayed (depending on balance model), enter the ser-
vice password “202122” and press ö.
– Press
