It is recommended to use Fluke ESA612 or equivalent meter (Refer to Appendix 3: AC Power plug
troubleshooting) to establish the test conditions. The nominal AC Mains should be 120VAC or
220VAC, to match the standard system plug.
Before you start the test, ensure the Equipment input power plug is connected to test socket
on the side of Fluke ESA612 meter and the system is in ON condition. If ground testing is
required for this system, verify that all ground testing results passed (see Table 1:
Conductive surface test points for AMX) are ≤ 0.3 Ohms before conducting leakage testing.
Leakage testing must be performed if the AC power plug has been replaced or disturbed.
The leakage current must not exceed 300 uA.
The Equipment Leakage Current test must be conducted under both normal condition and
Single Fault Condition. The test procedures for both the conditions are described below.
To perform the Equipment Leakage Current Test under normal conditions, follow the steps listed
below:
Refer to Table 5: Results of the leakage current test under normal conditions for AMX series
for normal test conditions and Appendix 2: Test Equipment for the test equipment used.
Refer to Table 4: Test Points for AMX series for the leakage current test points of the AMX
system for 120VAC or 220VAC AC Mains (site-specific input source).
Push μA to access the leakage current main menu.
Push the 'Direct Equipment button on the Fluke.
Push the Polarity button to select NORMAL.
Now connect one end of the test lead between the V/ Ω /A jack of the test meter and other end
to an exposed conductive surface of the DUT (Refer Table 4: Test Points for AMX series for test
points) ensuring that the input power plug of the DUT remains in the test socket on the side on
the Fluke ESA612.
The leakage current value will be displayed. Record the test results in Table 5: Results of the
leakage current test under normal conditions for AMX series for AMX series.
