When there's too much leakage current ...
Change another probe to confirm if the fail is caused by console.
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.
Inspect wiring for bad crimps, poor connections, or damage.
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.
If the leakage current measurement tests fail on a new
Ultrasound system and if situation can not be corrected, submit
a Safety Failure Report to document the Ultrasound system
problem. Remove Ultrasound system from operation.
