Rev. 5
Probe (Source) leakage current test
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:
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. It is abnormal if no
leakage current is measured. If no leakage current is detected,
check the configuration of the test equipment.
WARNING
Do not use the probe if the insulating material has been
punctured or otherwise compromised. Integrity of the insulation
material and patient safety can be verified by safety testing
according to IEC60601-1.
