Setting the ARC Mode
Background
ARC detection, otherwise known as flashover
detection, detects fast voltage or current
transients that are not normally detected. Arcing
is usually an indicator of poor withstanding
insulation, electrode gaps or other insulating
problems that cause temporary spikes in current
or voltage during ACW and DCW testing.
There are three ARC detection settings: OFF,
ON AND CONTINUE, ON AND STOP.
The ON AND CONTINUE setting will detect
arcs over the ARC current level and continue
the test, the ON AND STOP setting will stop the
test when an arc is detected.
ARC mode settings only apply to ACW and
DCW tests.
Steps
1. Press the UTILITY key on the front
panel when the tester is in EDIT
status. The tester will go to the
MANU Utility for the current test.
