6. Read the current leakage indicated on DMM.
NOTE
If either reading is greater than the appropriate specification below, 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
7. Set the GND switch on the leakage tester to CLOSED.
8. Read the current leakage indicated on DMM.
9. Set the polarity switch to RVS.
10. Read the current leakage indicated on DMM.
NOTE
If the reading is greater than the specification below, and the device under
test is powered from 100-240 V/50-60 Hz, the device under test fails.
Contact GE Technical Support.
100 µA (0.1 volts on the DMM), and the device under test is powered from
100-240 V/50-60 Hz
11. Set the power switch of the device under test to OFF.
Test completion
1. Disconnect the leakage tester from the power outlet.
2. Disconnect all test equipment from the device.
3. Disconnect the device power cord from the leakage tester.
NOTE
Due to IPX7 rating, the ApexPro CH and T14 Transmitters are not field
repairable.
1. Perform visual inspection.
2. Perform the communication tests.
3. If an oximeter is being used with the transmitter, perform the Oximeter
operational tests for the applicable oximeter.
