Technical Information
Test Time Setup
1
Program the Test Time for some value that allows for correct characterization
of the necessary test time to reach at least one decade less than that of
Setpoint 1 (reject level).
2
Input the desired Test Time.
Set Point 1 Setup
1
Input the Leak Rate value that is a failed/reject condition.
2
Typically, a greater than condition is programmed.
Set Point 2 Setup
You can choose between the two setpoints:
1
Input the Leak Rate value that is a failed/reject condition.
2
Typically, a greater than condition is programmed.
A Typical Auto Sequencer application uses either Set Point 1 or Setpoint 2 for the
NOTE
desired leak rate reject set point.
Using Set Point 1 and 2 together (Optional)
Some applications utilize a reference leak during the test cycle to validate that the
leak detector is still calibrated and sensitive to helium.
Set Point 1 is set up for the leak rate reject level (>).
Set Point 2 is set for the reference leak (<).
If the leak rate falls below the reference leak value (Set Point 2) at the end of the test cycle,
NOTE
the leak detector reports Rejected/Hold. This type of a reject is a system level failure. This
could be related to a fixturing issue, operator error or system performance.
Pressure Set point (High & Low Limit) - Optional
High Limit - Input the high-pressure limit that must not be exceeded during the test.
Low Limit - Input the low-pressure limit that must be maintained throughout the test.
Files: The operator can store up to three setup configurations:
AutoS 1-3.
