It is often useful to perform a particular test on an asset in isolation. If for instance an asset had previously failed a particular test and had subsequently
been repaired it may be useful to verify the repair before commencing with a full test sequence. Alternatively the test could be used during repair in
order to highlight the area at fault. Quick-check enables the selective application of any of the tests that would normally be applied to the asset. The
asset ID is entered in the normal way, recalling the asset record. The individual tests specified for the asset group will then be displayed, allowing any
one to be run independently. In Quick-check mode no results are stored and the asset history is not changed.
1 From the main screen, press the QUICK-CHECK key.
2 Scan or Type in the Asset ID and press the
OK
key.
3 Toggle the left-hand keys to display the required test from the list pre-set for the group.
Operation and earth leakage tests will not be available unless the asset supply voltage agrees with the
actual
PAT4 supply voltage.
Ensure that the correct leads and configurations are used for each test. Refer to the diagrams located
inside the lid of the
PAT4 .
For an Operation test, ensure that the asset is in a safe condition to run and
that no hazards are present.
4 Appropriate on-screen warnings are displayed for the selected test. Comply with all instructions and
press the
OK
key to continue.
5 Quick-Check results are displayed. Press the OK key.
6 Press the
YES
key to repeat the same test or press the
NO
key to return back to the
Quick-Check selection screen.
7 Use the
ESC
ape key to return to the Main screen.
