Volt Sensor (220-0103) Operation Faxback Doc. # 31949 When the Volt Sensor is positioned near a wire (outlet terminal, switch power, and any electrical unit under power) there is a capacitance between the wire and the Volt Sensor. It is designed to detect live voltage for 50/60 Hz in the range of 70 to 440 VAC. MODE OF OPERATION Place the Volt Sensor near the wire or appliance. While testing, press the button on the upper side of the Volt Sensor. The LED will light up if the wire or the appliance is powered. You can follow the presence of the voltage by following the wire up to the end. Two batteries are used. To change batteries, slide the top cover of the Volt Sensor and change them. (IR-03/21/96)
