6. Read the leakage current indicated on the DMM.
If the reading is greater than 50 µA (0.05 volts on the DMM), the
device under test fails this test and should be repaired and tested
again.
127(
The AAMI and IEC single fault condition (ground open) is 50 µA,
whereas the normal condition (ground closed) is less.
7. Change the leakage tester polarity switch to the RVS position.
8. Read the leakage current indicated on the DMM.
If the reading is greater than 50 µA (0.05 volts on the DMM), the
device under test fails this test and should be repaired and tested
again.

The AAMI and IEC single fault condition (ground open) is 50 µA,
whereas the normal condition (ground closed) is less.
9. Change the GND switch to the CLOSED position.
10. Read the leakage current indicated on the DMM.
11. If the reading is greater than 10 µA (0.01 volts on the DMM), the
device under test fails this test and should be repaired and tested
again.
12. Change the leakage current switch to the RVS position.
13. Read the leakage current indicated on the DMM.
14. If the reading is greater than 10 µA (0.01 volts on the DMM), the
device under test fails this test and should be repaired and tested
again.
15. Set the power switch of the leakage tester to OFF.
16. Repeat all previous steps for the TEMP/CO connector using the
appropriate test body.
