Test Time
5.1.3.8.2 Auto Sequencer Set-Up
Attach the test fixture with the part to be tested (known good test object) on to the leak
detector test port.
5.1.3.8.2.1 Rough Time Setup
Determines the amount of allowable time for the leak detector to evacuate the test object to
the Transfer Point - Transfer Pressure.
To test:
1. Select Test Configurations > Advanced Features > Setup.
If the transfer pressure is not achieved within the pre-selected rough time, the system
aborts the cycle and goes into Hold mode.
Do not activate or program any Set Points.
2. Program the Rough Timer for some unrealistic amount of time, like 200 secs.
3. Program Test Time for 30 secs and press Test.
Allow the test to complete (system vents).
4. Program the Rough Time as displayed in the Rough Time window.
Agilent Technologies Helium Leak Detector
This setting tells the system when to perform the test against the set
point values. For example, you may set 20 seconds for the Test
Time. At the end of 20 seconds, the system determines if the part
has passed or not and then makes an indication by either going to
VENT (Pass) or going to HOLD (Fail) and displaying the reject set
point failure on the Home screen. The final leak rate value appears
on the Home screen regardless of a pass or failed criteria. The next
test cycle (pressing Test) clears the leak rate value (setup below).
The Test, Vent and Zero functions are available in this

application setup. The Test and Vent buttons aid in setting up
the Rough and Test Timers. The Zero function is extremely
helpful in zeroing out unwanted background associated with
the test fixture. The zeroing set up helps in reducing the test
time.
Factory Default - Transfer Point (Transfer to Test Pressure) is 1
