PAT4 will apply each of the allocated tests for the appropriate Group, in the correct sequence. If AUTOPASS has been selected under the SETTINGS
option, testing will proceed automatically with PAT4 determining the pass/fail status according to the pre selected Group limits. If
MANUAL
has been
selected, PAT4 will pause after each test and display a Pass / Fail decision prompt. An asterisk is placed against either the
PASS
or
FAIL
button depending
on the whether the value falls within the Test Group’s passband.
PAT4 will conduct a pre-test to confirm that electrical continuity exists within the appliance i.e. that it has been switched On, and that any fuses present are
not ruptured. If the asset is very high or very low resistance, PAT4 will warn that the asset may accordingly be Open or Short Circuit. You have the option
of
RETRY
(asset turned On?)
FAIL
, or
IGNORE
the warning. Some assets containing heating elements, filament lamps or large motors may offer very low
resistance in their de-energised state, causing PAT4 to warn of a possible short circuit. In such cases, the warning can be ignored. When all required tests
have been completed the results may be stored in PAT4 memory.If a printer is attached to PAT4 ’s parallel output, a simple listing of test results can be
printed. If a printer is not attached or this feature has been disabled (See Settings section), PAT4 will automatically skip the printing process.
