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

The VGC401 works in the following operating modes:

• Measurement mode for displaying measurement values or status mes-sages (→ 28)

• Parameter mode for entering or displaying parameters (→ 31)

• Test mode for running internal test programs (→ 47)

• Program transfer mode for updating the firmware (→ 83)
