1. Connect three dry cell batteries (1.5 V) in series.
2. Connect the (+) side of the battery to terminal No. 3 of the sensor, and the (-) side of the battery to terminal No. 1, and apply a voltage of 4.5 V between terminals No. 3 - No. 1.
3. With voltage applied, measure the voltage between connector terminals when the sensor link is moved slowly up and down.
