6 Maintenance,
Repair
Gauge failures due to contamination and wear and tear,
as well as expendable parts (e.g. filament), are not
covered by the warranty.
INFICON assumes no liability and the warranty becomes null
and void if any repair work is carried out by the end-user or third
parties.
6.1 Adjusting
the
Gauge
The gauge is factory calibrated. Due to long time operation or
contamination, a zero drift could occur. Periodically check the
zero and adjust it if necessary.
For adjusting the zero, operate the gauge under the same con-
stant ambient conditions and in the same mounting orientation
as normally.
The gauge is adjusted to default values. However, it can also be
adjusted to other pressure values, if the exact pressure value is
known (reference measurement).
n
If you are using a seal with centering ring and filter, check
that they are clean or replace them if necessary
(
→
"Deinstallation").
o
Put the gauge into operation and operate it at atmospheric
pressure for at least 10 minutes.
