7.4.5.1 Fore Pump Type and Exhaust Pump Activation
The fore pump type and exhaust pump are configured at the factory or can be configured by
a service engineer.
NOTE When the Last Service date is updated/changed the Operating
Hours reset to Zero.
7.4.6 Maintenance: Gauge Calibration
A display of <1.0E-03 indicates the pressure is less than the lowest displayable pressure of
the TC gauge, which is 1.0E-03. Use this screen to perform a calibration on the test port
thermocouple gauge. Calibrate the thermocouple gauge for the most accurate operation.
❑ Select Gauge Calibration from the Maintenance Menu selection.
Use this screen to:
❑ Set a calibration point at atmosphere.
❑ Set a calibration point at a low vacuum level (<= 1E-4 Torr).
Figure 7-12 Maintenance: Gauge Calibration
Buttons and Fields
Test Port Vacuum Calibrates the thermocouple gauge zero value. Do this at or below
1E-4 Torr.
