Probe Leakage Current Test
10-4-11-1
Definition
This test measures the current that would flow to ground from any of the probes through a patient who
is being scanned and becomes grounded by touching some other grounded surface.
10-4-11-2
Generic Procedure
Measurements should be made with the ground open and closed, with power line polarity normal and
reversed, and with the unit Off and On. For each combination, the probe must be active to find the worst
case condition.

NOTE:
Each probe will have some amount of leakage current, 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.

Meter Procedure Using Probe Adapter
Follow the Safety Analyzer tool instruction to test each transducer for leakage current.
The electrical Safety Analyzer tool should be calibrated and compliant with AMMI/ESI 1993 or IEC
60601 or AS/NZS 3551.
10-4-11-4
No Meter Probe Adapter Procedure
Follow the Safety Analyzer tool instruction to test each transducer for leakage current.
The electrical Safety Analyzer tool should be calibrated and compliant with AMMI/ESI 1993 or IEC
60601 or AS/NZS 3551.
