Description
The Santronics AC Sensor, Part # 3115, is the first and only UL listed AC voltage sensor to be manufactured 100% in the U.S.A. The AC Sensor is a hand-held device for determining the presence or absence of 50-600 volts AC in insulated wires, wall receptacles, fuses, junction boxes, switches, and other voltage carrying electrical systems. The AC Sensor determines defective grounds, reverse polarity, and induced voltage.
It is not necessary to disconnect the system in question because no contact is required for operation, and current flow is not necessary to locate voltage. Simply touch the plastic tip to a connection point or move it along an insulated wire. If AC voltage is present, the LED light in the tip will glow cherry red.
There is no ON/OFF switch, since switches can malfunction over time. As a result, the AC Sensor is always on and ready to use.
Benefits
Visual alert to locate voltages of 50-600V AC.
No electrical contact required.
Only uses two AAA 1.5V alkaline batteries (included).
No on/off switch - always ready to use.

Operating Instructions
Always hold unit by its body. Keep fingers away from the tip. Remove the end cap to replace batteries.
Simply touch the plastic tip to a connection point or move it along an insulated wire. If AC voltage is present, the tip glow red. The tip will emit a steady glow in the presence of AC line voltage. It will flicker in the presence of static electricity.
Caution 1. Prior to each use, as a safely practice, always test the instrument on a known live circuit to verify proper operation. Treat your AC Sensor with care as you would any other test instrument. Clean Ultimate AC Sensor with damp cloth.
Caution 2. In testing indoor insulated cable where the fibrous filler becomes saturated with water, which is conductive, an electrical connection is formed between the filler and the ground circuit. The length of cable that has become wet is essentially shielded. If a voltage is present on a conductor in this cable, the electric field normally radiated by the voltage will be attenuated by this shielding, and the AC Sensor may not glow even though a voltage is present.
Always approach wet indoor insulated cable with utmost caution. NOT FOLLOWING THESE CAUTIONS MAY RESULT IN BODILY HARM. Cable of this type is specified for indoor use only. It will be subjected to immersion in water only in rare conditions such as flooding.
Defective Grounds: Electrical equipment that has a metal enclosure and is improperly grounded or has a detective ground will always result in the Sensors tip emitting a steady red glow.
