I use LTS 25-NP current sensor to measure ac current grid. I just built it. I tried to calibrate it using simple circuit consists of a single phase source and high power resistor. The current is flowing when I change the source voltage as appearing in the Ammeter but the output voltage from the sensor still 2.5 V ( 2.5 V means zero current flowing). The current sensor is then connected to a simple DC circuit to check it. The sensors worked accurately. I didn't know what is the problem with measuring AC current using this sensor.
Can you please help me.
