Replacing the Balance PCB
Note: To replace the balance PCB, you need the SARTOCAS Service Program for
PCs, version 1.10 or newer, or the PSION server, CAS version 4.5 or newer.
Before replacing the PCB, you should attempt to copy the data from the old
PCB and store it.
This is done using the SARTOCAS Service Program for PCs, version 1.10 or
newer, or the PSION server, CAS version 4.5 or newer.
The required procedures are described in the corresponding program instruc-
tions.
If it is not possible to read the data records or if no replacement PCB is avail-
able, you can order a pre-programmed PCB from the Sartorius factory. Make
sure you include the correct balance model and serial number when ordering
the PCB.
