9.1 Maintenance
If the instrument is used properly, no special maintenance is required
in normal operation.
9.2 Rectifyfaults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
Maximum reliability is ensured. Nevertheless, faults can occur during
operation. These may be caused by the following, e.g.:
•
Measured value from sensor not correct
•
Voltage supply
•
Interference in the cables

signal as well as to evaluate the error messages via the display. The
procedure is described below. Further comprehensive diagnostics
can be carried out on a PC with PACTware and the suitable DTM. In
many cases, the causes can be determined in this way and faults
rectied.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no.
