VS Series Helium Mass Spectrometer Leak Detectors
Test Time
To configure the auto sequencer mode:
1. Press the blue check to turn on the Auto Sequencer.
The pass/fail criterion is based on the reject set points that are enabled.
2. Press the value button associated with the Rough time.
The data entry pad appears.
3. Enter the time and press OK.
4. Press the value button associated with the Test time.
The data entry pad appears.
5. Enter the time and press OK.
6. Press TEST and let the system record the actual time spent in roughing. After the test is
complete, use the recorded rough timer value to set an appropriate rough time.
2-24
Determines the amount of time that the leak detector remains in
test before it compares the measured leak rate with the selected
reject set point. Allow sufficient time for the leak rate reading to
stabilize before the system makes a pass/fail decision. This is a
function of the part configuration and the leak rate specification. In
Auto Sequencer mode, the leak detector remains in test for the
entire duration of the preselected test time.
