• the digital input "Remote Zero" (briefly apply the
supply voltage to pin 10),
• an INFICON Vacuum Gauge Controller (VGC series).
While the gauge is being heated and/or under atmos-
pheric pressure, the zeroing function is locked in order
for operating errors to be prevented.

Evacuate the gauge to a pressure according to the table

If the final pressure is too high for zero adjustment (>25%
of the F.S.), the zero cannot be reached and the
<STATUS> LED blinks green. If this is the case, activate
the factory setting and adjust the zero again (
→  34).

Operate the gauge for at least 2 hours (until the signal is
stable).
