10-6-4 Grounding Continuity
Measure the resistance between the third pin of the attachment plug and any exposed metal parts on
the system. The Ground wire resistance should be less than
0.2 Ohms. Refer to the procedure in the

10-6-4-1 Ground Continuity Testing - Generic Procedure
Follow these steps to test the Ground wire resistance:
1.) Turn the Vivid S5 N or Vivid S6 N unit OFF.
2.) Connect one of the Ohmmeter probes to the tested AC wall outlet (Ground pin).
3.) Using the other Ohmmeter probe, touch the exposed metal part of the Vivid S5 N or Vivid S6 N unit.
4) Set the meter Function switch to the Resistance position.
5) Measure and record the Ground wire resistance.
This should be less than 0.2 Ohms.
