MAIN DISPLAY
This is the leakage rate measured from the gauge on channel 4.
Note: The main display may show the Leakage Rate (as in this
example) or instantaneous Leakage.
Figure 33: Leakage Mode
Figure 33 shows a sample window for Leakage Mode. In Leakage Mode, all upper displays
show a pressure reading, provided the displays are hooked up to active sensors and the sensors
are reading within their range. The main display shows either leakage rate, or instantaneous
leakage.
Leakage rate is the leakage over a user-defined time base. The leakage rate display shows the
rate in pressure units/second. For example, the leakage rate may be 3 Torr per 30 seconds, where
Torr is the pressure unit, and 30 seconds is the user-defined time base. The display shows the
rate as .1 Torr because a rate of 3 Torr/30 seconds equals a rate of 0.1 Torr/second. Refer to
