Left to right (1-positive 15V;2-negative 15V;3-single input;4-GND),the corresponding electric meter interface. Using hall sensor, pay attention to the direction of current, the nameplate on the direction of the arrow need to test the actual current in the same direction. The actual sensor range in the sensor, the attention should not be used as super range.
