4.3 AUTO mode tests – Class I
This test is performed to evaluate the technical condition of the tested devices belonging to the safety
Class I equipment. The principles for carrying out each single test, and setting their parameters, are
the same as for the measurements in the manual mode.
After passing visual examination check (press PASS button), when the AUTO-TEST
( icon is displayed) mode is on, the tester will automatically run subsequent
tests. The ongoing measurements can be stopped by pressing START/STOP button.
NOTE:
Some tests in autotest procedures require the tester to be powered from the mains. When it's not
connected the test sequence can't be initiated, mains plug icon: is flashing. In order to start the
selected set of tests, the mains power supply must be connected.
PAT-2E and PAT-10 testers allow to run the tests from their batteries when the mains power supply is
disconnected. In order to do that, press and hold CL I button for 3 seconds. The tester will
enter the battery powered measurement mode. If the measurement procedure included some tests
requiring mains power supply (ie. I
Δ
, I
T
) they will be turned off. If the measurement of R
PE
with 10A
test current has been selected, it will be switched into 200mA test current version. Limits and test
time duration settings remain unchanged. After changing the measurement mode (selecting another
autotest or manual test), the tester will return to default settings that require mains power supply. .
