5.1.3.8.2.2 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.
5.1.3.8.2.3 Set Point 1 Setup
1. Input the Leak Rate value that is a failed/reject condition.
2. Typically, a greater than condition is programmed.
5.1.3.8.2.4 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.
NOTE A Typical Auto Sequencer application uses either Set Point 1 or
Setpoint 2 for the desired leak rate reject set point.
5.1.3.8.2.5 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 (<).
NOTE If the leak rate falls below the reference leak value (Set Point 2)
at the end of the test cycle, 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.
5.1.3.8.2.6 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
