Hall Effect Current Sensor (Trimpot) Calibration

After hardware installation and wiring is complete, perform this calibration procedure. Repeat it on a yearly basis during outage.

  1. Remove the grounding and metering ropes from the Shaft Grounding Assembly so that no current is flowing through the ground conductor.

  2. While looking at the ground current DC reading on the Assurance Monitoring System display, turn the trimpot (A) until the reading is as close to 0.00 amps as possible. +/- 0.1 amps or less is acceptable.
