Outlet test
Illustration 2-2
Note:
No outlet tester can detect the condition where the Neutral (grounded supply)
conductor and the Grounding (protective earth) conductor are reversed. If later tests
indicate high leakage currents, this should be suspected as a possible cause and the
outlet wiring should be visually inspected.
2-3-2 Ground Continuity
Caution:
The patient must not be contacted to the equipment during the test because it
may cause electric shock.
Caution:
Measure the resistance from the third pin of the attachment plug to the
exposed metal parts of the case (See Illustration 2-3), this should be less than 0.2 ohms.
