Cycle End Method
The Cycle End Method may be set to either Manual or Automatic. See the following
options for Automatic settings.
Rough Timer
A rough timer option can be used to verify if the pump down state is too long. If the
timer expires before the rough step is complete the test cycle will end automatically
Total Test Timer
The timer option is full test time from start cycle initiation. When the timer expires the
cycle will end.
Show Last Test Result
This option keeps the final leak rate from the test on the test screen. The text “Last
Result” is displayed. See
image below for example.
Zero Settings
NOTICE:
Use of Zero function
The use of the Zero function is recommended when the background signal is
stable and significant.
The Zero function can assist the operator in finding smaller leak rate variations. Zero
function features include:
•
Recording signal background when the zero function is activated. This value is
subtracted from the current signal.
•
Signal limit of either 100 or 1000 times lower than the background.
•
If signal increases while zero is on, the Zero function stays on but is not functional.
To re-zero, the user must deactivate Zero function and then reactivate.
•
When the signal decreases while zero is on a new reference, background is
automatically calculated.
