IRECTION GB091046, REVISION 2 VIVID E9 / VIVID E7 BT’13 SERVICE MANUAL
10 - 24 Section 10-6 - Electrical Safety Tests
10-6-7 Probe leakage current test
10-6-7-1 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.
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.
