Vacuum Gauge Controller AGC-100
36
The offset value is displayed and readjusted according to the actual measurement
value.
Available for the following gauges:
 Pirani
(PVG)
 Pirani / Capacitance
(PCG)
 Cold cathode
(IMG)
 Cold cathode / Pirani
(FRG-70x)

Hot ionization / Pirani
(FRG-720 / -730)
 Capacitance
(CDG)
The offset correction affects:
 the displayed measurement value
 the displayed threshold value of the switching functions
 the analog outputs at the CONTROL connector (

I  Offset correction factory-deactivated
e.g.
OFFSET 9.53

in the relevant units of measure-
ment)
 Press key for >1.5 s:
The offset value is readjusted (the actual measurement
value is accepted as new offset value).
Reset the offset value.
 Save change and return to read mode.
When offset correction is activated, the saved offset value is subtracted from the
actual measurement value. This allows measuring relative to a reference pressure.
