The test passes when all readings measure less than the values shown in Table 10-15 and Table 10-
16. Record all data on the PM Inspection Certificate.
. 
CAUTIONEquipment damage possibility. Never switch the Polarity and the status of Neutral when the unit 
is powered ON. Be sure to turn the unit power OFF before switching them using the POLARITY 
switch and/or the NEUTRAL switch. Otherwise, the unit may be damaged

Section 10-8
When Theres 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. Ensure star washers are under all ground studs.
Inspect wiring for bad crimps, poor connections, or damage.
Test the wall outlet; verify it is grounded and is free of other wiring abnormalities. Notify the user or 
owner to correct any deviations. As a work around, 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
Test the probe in another connector to isolate if the fault lies with the probe or the scanner.
NOTE: Each probe will have some amount of leakage, dependent on its design. Small variations in 
probe leakage currents are normal from probe to probe. Other variations will result from 
differences in line voltage and test lead placement. The maximum allowable leakage current for 
body surface contact probe differs from inter-cavity probe. Be sure to enter the correct probe 
type in the appropriate space on the check list.
If excessive leakage current is slot dependent, inspect the system connector for bent pins, poor 
connections, and ground continuity.
If the problem remains with the probe, replace the probe.
PERIPHERAL FAILS
Tighten all grounds. Ensure star washers are under all ground studs.
Inspect wiring for bad crimps, poor connections, or damage.
STILL FAILS
If all else 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 can not be corrected, submit 
a Safety Failure Report to document the system problem. Remove unit from operation.
ECG FAILS
Inspect cables for damage or poor connections.
