9.4 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
Therstmeasuresare:
•
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

Connect a multimeter in the suitable measuring range according to
the wiring plan. The following table describes possible errors in the
current signal and helps to eliminate them:
