In case of exchanging the front panel unit all these
data have to be saved first and later on entered into
the new front panel unit by means of the service
software.
The main CPU contains also the real-time clock
and the associated back-up battery.

Figure 2: Measuring module
The measuring module is designed as an inde-
pendent unit and can be exchanged with another
one of the same connecting system.
It stores all relevant amplifier data like calibration
factors and zeroing results as well as calibration
factors for measuring high voltage. With older edi-
tions of the measuring module, only the internal HV
can be measured and monitored.
Since the results of the system tests are stored in
the main CPU, these data are however no more
comparable after a replacement of the measuring
module.
