9.4 Rectify faults
The operator of the system is responsible for taking suitable meas
-
ures to rectify faults.
The first measures are:
•
Evaluation of fault messages via the adjustment device
•
Checking the output signal
•
Treatment of measurement errors
Further comprehensive diagnostics options are available with a PC
with PACTware and the suitable DTM. In many cases, the reasons can
be determined in this way and faults rectified.
The below tables show typical examples for application-relevant
measurement errors. There are two measurement errors:
