3-4 Grounding Continuity
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 IEC 601-1.1.
The patient must not be connected to the equipment during this test.
The Dale 600 measures line cord resistance from the third pin of the attachment plug to the meter's Chassis
Cable clamp. Test the grounding continuity of the system to all exposed metal parts in accordance with the
IEC 601-1.1 procedure as above. See Illustration 3-4. Refer to the Dale 600 Instruction Manual for meter
self tests and operation. Record measured resistance of the grounding continuity on the appropriate form.
The ground wire resistance should be less than 0.2
Use any safety analyzer.
