NOTE
Degas Limitations: All gauges operate simultaneously, but only
two hot filament gauges can degas at the same time. Additional
degasses are not allowed by the system.
To terminate degas manually, select Degas OFF . The field reverts to
Fil1 or Fil2. Turning off degas momentarily turns off emission.
CAL (CNV and AUX):
Convection TC gauges and the CT-100, PVG500 and PCG500 are
calibrated using this control. The XGS-600 uses Agilent's Smart
Cal, which automatically determines whether to perform a vacuum
calibration or atmosphere calibration based on the pressure pre-
sented to the sensor.
Active Gauges:
When using FRG700 or FRG720/730, pressing CAL only performs
an atmosphere calibration. As determined by the Smart Cal feature.
When using CDGs, pressing CAL only performs an offset calibra-
tion (zeroing). As determined by the Smart Cal feature.
NOTE
Convection gauge calibration at atmosphere depends on
orientation. Be sure to install the gauge sensor in final
orientation before calibrating.
To calibrate:
1. Cursor down to the CAL control for the required gauge.
2. Present either vacuum or atmospheric pressure to the gauge.
(Allow the gauge to stabilize for 15 minutes after first power up.)
3. Press OK .
Vacuum calibration defaults to 1E-4T and atmosphere calibration
defaults to 760T (or equivalents in mbar and Pa). See “System Setup
Screen” on page 37 for modifying atmospheric pressure to your
regional value. See “Sensor Setup Screen” on page 31 for selecting
gas type. See “Convection Gauge Board” on page 57 for activating
the same calibration using rear-panel I/O controls, and “ASCII
Serial Commands” on page 67.
It is normal for the vacuum reading of Convectorr and TC gauges to
fluctuate somewhat when at high vacuum after calibration. Typi-
cally, you can expect the readings to be anywhere from 1.0E-4 Torr
to ~3.0E-4 Torr with an occasional reading as high as 1.0E-3 Torr
(or equivalent mbar and Pa).
After performing Cal for CDGs , it is normal for Under to sometimes
appear.
