10-7-6 Probe leakage current test
10-7-6-1 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.
NOTE:
Some leakage current is expected on each probe, depending 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. It is abnormal if no
leakage current is measured. If no leakage current is detected,
check the configuration of the test equipment.
