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.
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
