Outlet Test Wiring Arrangement - USA & Canada
Test all outlets in the area for proper grounding and wiring arrangement by plugging in the neon outlet
tester and noting the combination of lights that are illuminated. Any problems found should be reported
to the hospital immediately and the receptacle should not be used.
NOTE:
No outlet tester can detect the condition in which the Neutral (grounded supply) conductor and the
Grounding (protective earth) conductor have been reversed. If later tests indicate high current leakages,
this should be suspected as a possible cause and the outlet wiring should be visually inspected.

The patient or operator must not come into contact with the equipment during this test.
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. Refer to the procedure in the IEC 601-1.1.
