SET-PTS (Set Points)

3-6
XGS-600 Gauge Controller
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 3-14 for modifying atmospheric pressure to your
regional value. See "Sensor Setup Screen" on page 3-9 for selecting
gas type. See "Convection Gauge Board" on page A-4 for activating
the same calibration using rear-panel I/O controls, and
Appendix Appendix B. "Serial Commands" on page B-1.
Displays the setpoints activated. The setpoints are numbered on the
Set Point screen (page 3-7).
The setpoint number appears if all following conditions met:
❑
The setpoint is assigned to the sensor,
❑
The setpoint screen is set to AUTO for that setpoint,
❑
And the setpoint has been activated.
