External Linearization
There are two ways to perform external linearization:
1. with the Sartorius service software (PSION Server or SARTOCAS Service
Software for PCs) - if the adjustment error is greater than
±
2%, or
2. as described in this manual, with the balance in the service mode.
External Linearization with Manual Input of Weight Values
If adjustment weights of sufficient accuracy are not available (at least one digit
greater than the display accuracy) or if no calibration certificate is available,
you can program the balance with the weight value including all necessary
decimal places.
If this is the case, follow the steps listed below:
Manual Input of the Linearization Weights
