5-Ground leakage current test
Overview
Before performing other leakage current tests for the device, perform the ground leakage
current test.
Measure the leakage current as follows:
• Measure the ground leakage current from the ground terminal of the DUT.
• No test lead needs to be connected. The 601 PRO tester will automatically connect to the
internal measurement device.
Test process
• Performing the test
1. On the main panel, insert the DUT plug into the auxiliary output on the front panel of the 601
PRO tester when there is no power on the output end, and then turn on the DUT.
2. Connect the applied part of the device to an available applied part terminal of the 601 PRO
tester.
3. Press 4. The ground leakage current test appears on the screen and the test begins.
• Soft key 1 implements switching between the positive and negative polarities of the DUT.
• Soft key 2 implements DUT output switching between grounding and non-grounding.
• Soft key 3 implements switching between L2 and non-L2 (single fault).
• Soft key 4 implements switching between applied part grounded and applied part not
grounded.
4. Press the print key to print the latest measurements.
