IRECTION
10-7-4 Grounding Continuity
Electric Shock Hazard!
CAUTION
The patient or operator MUST NOT come into contact with the equipment during this test
!! CAUTION:
Measure the resistance from the third pin of the attachment plug to the exposed metal parts of the case.
The ground wire resistance should be less than 0.2 ohms.
Reference the procedure in the IEC60601-1-1.
GROUND PIN
Lacquer is an isolation barrier! Resistor may be high-impedance!
CAUTION
Measure only on blank parts, stated in
!! CAUTION:
10-7-4-1 Meter Procedure
Follow these steps to test the Ground wire resistance.
1.) Turn the Voluson E8 / Voluson E6 system OFF.
2.) Plug the system into the meter, and the meter into the tested AC wall outlet.
3.) Plug the black chassis cable into the meter's "CHASSIS" connector and attach the black chassis
cable clamp to an exposed metal part of the Voluson E8 / Voluson E6 system.
4.) Set the meter's "FUNCTION" switch to the RESISTANCE position.
5.) Set the meter's "POLARITY" switch to the OFF (center) position.
6.) Measure and record the Ground wire resistance.
