Rectify faults

Reaction when malfunction occurs
The operator of the system is responsible for
taking suitable measures to rectify faults.
Fault rectification
The first measures are:
•
Evaluation of fault messages
•
Checking the output signal
•
Treatment of measurement errors
A smartphone/tablet with the VEGA Tools app or
a PC/notebook with the software PACTware and
the suitable DTM offer you further comprehen-
sive diagnostic possibilities. In many cases, the
causes can be determined in this way and the
32
faults eliminated.
