ABSTRACT:
A method of adjusting and testing for proper operation a current sensor by applying a threshold current value to the current sensor and adjusting the current sensor to a point just past the threshold of operation. Proper operation of the current sensor is tested by applying a non-operate current value followed by an operate current value to the sensor and checking for respective non-operate and operate output signals from the sensor. Messages, pass/fail indication, and audio signals are provided to signal test results to an operator.
