Model 3000 AC Detector, Non-contact, by Santronics
Description
The Santronics Ultimate AC Sensor, Part # 3000, 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.
It is not necessary to disconnect the system in question. Electrical contact is not 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 tip will glow red, and you will hear an audible tone. The illumination will stop at a break in the circuit or wire and this allows the AC Sensor to he used as a troubleshooting instrument.
The Ultimate AC Sensor operates very much like the Santronics AC Sensor 3115, the choice of OSHA, but adds an audio alert as a feature. The audio alert reacts only to an AC voltage field and does not beep when it comes in contact with a static electric field.
There is no ON/OFF switch, since switches can malfunction over time. As a result, the Ultimate AC Sensor is always on and ready to use.
Benefits
- Locates 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.
- Both sound and visual alerts.
- Audio alert immune to static electricity.
Operating Instructions
Always hold unit by its body (2). Keep fingers away from the tip (3). Remove end cap (1) 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, and you will hear an audible tone. The tip will emit a steady glow in the presence of AC line voltage. It will flicker in the presence of static electricity. The audio buzzer will not react to 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 Sensor's tip emitting a steady red glow. If there is enough electrical field present on the metal enclosure, the result will be a steady red glow and an audible tone.
