2-3-5 When there's too much Leakage Current...

Chassis Fails
Check the ground on the power cord and plug for continuity. Ensure the ground is not
broken, frayed, or intermittent. Replace any defective part.
Tighten all grounds.
Inspect wiring for bad crimps, poor connections, or damage.
Test the wall outlet and verify if it is grounded. Notify the user or owner to correct any
deviations. Check the other outlets to see if they could be used instead.
Note:
No outlet tester can detect the condition where the white neutral wire and the
green grounding wire are reversed. If later tests indicate high leakage currents, this
should be suspected as a possible cause and the outlet wiring should be visually
inspected.
Probe Fails
Replace the probe and try again.
Peripherals Fail
Tighten all ground connection screws.
Inspect wiring for bad crimps, poor connections, loose screws or damage.
Still Fails
Begin isolation by removing the probes, external peripherals, then the on board ones, one
at a time while monitoring the leakage current measurement.
New Unit
If the leakage current measurement tests fail on a new unit and if situation cannot be
corrected, submit a Safety Failure Report to document the system problem. Remove the
unit from operation.
