A.5 Earth Leakage Test
Run an Earth Leakage test on the device being tested before performing any other leakage
tests.
Leakage current is measured the following ways:
„ Earth Leakage Current, leakage current measured through DUT outlet Earth
„ Earth Leakage Current AP-EARTH (ALL Applied Parts connected to Earth), leakage
current measured through DUT outlet Earth
There is no need to attach a test lead; the 601PRO automatically connects the measuring
device internally.
To Perform the Test
1. From the MAIN MENU, or with the outlet unpowered, plug the DUT into the 601PRO
