Make sure the VGC401 is correctly installed and the
specifications in the Technical Data are met.
The power switch is on the
rear of the unit.
Turn the VGC401 on with
the power switch (or cen-
trally, via a switched power
distributor, if the unit is in-
corporated in a rack).
After power on, the VGC401 …
• automatically performs a self-test
• identifies the connected gauge
• activates the parameters that were in effect before the
last power off
• switches to the Measurement mode
• adapts the parameters if required (if another gauge
was previously connected).
Turn the VGC401 off with the power switch (or centrally,
via a switched power distributor, if the unit is incorpo-
rated in a rack).
Wait at least 10 s before turning the VGC401 on
again in order for it to correctly initialize itself.

• Measurement mode
