Summary:

Procedure for measuring current flowing to ground from the shaft.

ELECTRICAL DANGER

Only qualified electrical personnel should take measurements at the remote test points. For any of the test points on the faceplate, use a hand-held voltmeter, oscilloscope, clamp-on ammeter, or other appropriate testing device. Always follow proper electrical safety procedures.

Ground Current Test Point

The ground current test points are connected to the Hall effect sensor drivers.

To measure current flowing to ground from the shaft

  1. Set an oscilloscope or digital voltmeter to measure in the mV scale. 

  2. Place the positive and negative probes on the Ground Current + and - test points, respectively.

  3. Refer to the following table to interpret that voltage reading as an associated current value.
