10-8-8 Type BF Patient Leakage Current Test - Probe
10-8-8-1 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.
Equipment damage possibility. Never switch the Polarity and the status of Neutral when the unit
CAUTION
is powered ON. Be sure to turn the unit power OFF before switching them using the POLARITY
!! CAUTION: switch and/or the NEUTRAL switch. Otherwise, the unit may be damaged.
