Vacuum Gauge Controller AGC-100
25
Measurement mode is the standard operating mode of the AGC-100 with display of
•
a bar graph (if required)
•
a measurement value for each measurement channel
•
status messages for each measurement channel
If required a bar graph may be displayed (
→
 44).
Certain gauges can be turned on and off manually, provided the gauge control is
set to
S-ON HAND
(
→
 41).
Available for the following gauges:
 Pirani
(PVG)
 Pirani / Capacitance
(PCG)
 Cold cathode
(IMG)
 Cold cathode / Pirani
(FRG-70x)
 Hot ionization / Pirani
(FRG-720, FRG-730)
 Capacitance
(CDG)
 Press key for >1 s:
Gauge switches off. Instead of a measurement value the
word OFF is displayed.
 Press key for >1 s:
Gauges switches on. Instead of the measurement value
a status message may be displayed.
For certain gauges the emission can be switched on and off manually, provided the
sensor parameter is set to
EMISSION HAND
(
→
 39).
Switching on the emission is only possible if the pressure is below
2.4×10
-2
mbar.
Available for the following gauges:

Pirani
(PVG)
 Pirani / Capacitance
(PCG)

Cold cathode
(IMG)
 Cold cathode / Pirani
(FRG-70x)
 Hot ionization / Pirani
(FRG-730 only)
 Capacitance
(CDG)
 Press key for >1 s:
The emission is switched off. The measurement value of
the Pirani sensor is displayed instead of the measure-
ment value of the hot cathode ionization sensor.
 Press key for >1 s:
The emission is switched on. The measurement value of
the hot cathode ionization sensor is displayed and lid
solid.
