6.3 TEST: General
Screen Instructions (Diagram 8):
1. Tap the TEST tab at the bottom of the page
2. Select desired UUT ID from the drop down box at the top of the page.
If desired UUT is not there, see section on creating a new UUT.
3. View the PROFILE ID drop down box and confirm that profile selected
is the desired pressure test profile, if not, select desired profile from
drop down list.
4. Select AS FOUND or AS LEFT radio button.
5. Tap TARE and wait until completed. This zeroes the ref. unit.
6. Tap DO TEST button.
7. To stop a test in process, tap the STOP button. This will stop and
cancel the test.
8. Target pressure will be generated and data will be automatically
recorded at each pressure point.
Note: If the Display Test Results in Graph Option is selected (see Edit Defaults
page) - a graph will appear displaying pressure vs. error after the pressure
sequence has been completed (Diagram 9).
9. To record data - Tap RECORD TEST RESULTS button
Note: Record Test Results Button has 3 states indicating the save status of test
results. When no test results are available to save, the button reads “No Results
To Save.” When results on screen have been saved, the button will change to
“Test Results Saved.” After a test is complete and before the data is saved, the
button will read “Record Test Results.”
10. To review data - Tap REVIEW TEST RESULTS button
11. To expand/collapse the Test Profile/Results window, double tap Test
Profile / Results window.
