1. Configure the leakage tester like the circuit shown below.
2. Connect the power cord of the device under test to the power
receptacle on the leakage tester.
3. Set the power switch of the device under test to ON.
4. Read the current leakage indicated on DMM.
5. Set the polarity switch on the leakage tester to RVS (reverse).
6. Read the current leakage indicated on DMM.
NOTE
If either reading is greater than the appropriate specification
below or the device under test fails, contact GE Technical
Support.
 300 µA (0.3 volts on the DMM), and the device under test is
powered from 100-120 V/50-60 Hz
 300 µA (0.3 volts on the DMM), and the device under test is
powered from a centered-tapped 200-240 V/50-60 Hz, single
phase circuit
 500 µA (0.5 volts on the DMM), and the device under test is
powered from a non-center-tapped, 200-240 V/50-60 Hz, single-
phase circuit
NOTE
Center-tapped and non-center-tapped supply circuits produce
different leakage currents and the UL and EN limits are
different.
7. Set the power switch of the device under test to OFF.
Enclosure Leakage Current
Perform this test to measure current leakage through the ground tabs on
the Video In connector on the device under test during normal operation.
NOTE
When testing the monitor, the device under test includes the optional
external power supply.
