To Perform the Test
1. From the MAIN MENU, or with the outlet unpowered, plug the DUT into the 601PRO
front panel outlet.
2. Attach the 601PRO RED input lead to the device’s Protective Earth terminal or an
exposed metal area.
3. Press shortcut key 3. The Protective Earth Resistance test is displayed.
4. Press SOFT KEY 3 to select a test current (1AMP, 10AMP, or 25AMP). The selected test
current is displayed in the upper right corner of the display.
5. Press START TEST to start the test. The test current is applied while resistance and
current readings are taken. This takes approximately 5 seconds.
6. Press the print data key at any time to generate a printout of the latest measurement(s).
NOTE
When "Over" is displayed for Ohms, this signifies that a valid measurement was not
obtained because either an open connection was detected or that the measurement
was not within range. Readings greater than 9.999 Ohms will be displayed as Over.
In Case of Failure
Once it reaches the limitation, stop using and inform the Customer Service Engineer for
analysis and disposal.
LIMITS
ALL COUNTRIES R = 0.2 Ω Maximum
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
