Technical Information
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.
To access:
1
Select Test Configurations > Applications Setup.
2
Select Auto Sequencer and press Set-Up and the following figure appears:
Figure 43 Auto Sequencer
The auto sequencer is used to automatically perform testing on a part, to maximize
testing throughput and to reduce the chances of accidentally accepting a bad part.
The auto sequencer is used in conjunction with Set Points 1 & 2 and Pressure Set
Point settings, which provide the criteria for pass or fail conditions.
Within the auto sequencer feature, there are two variables that must be set, Rough
Time and Test Time.
Rough Time
The Rough Time value is determined empirically and reflects the typical time
NOTE
required to rough the test object to the specified test pressure. Failure to achieve
the test pressure within the pre-selected rough time indicates a gross leak in the
test object or test fixturing, or that the time allowed was insufficient.
94
This setting indicates to the system the maximum time for the
leak detector to be in Roughing mode. If the Rough Time is
exceeded the test aborts and the system goes into Hold.
This is a failed condition. Ideally, the system goes into the
Roughing phase and then proceeds to TEST (setup below).
