Additional Details ------------------------------ Specification met: Product description: These AC/DC Voltage Detectors from Santronics are ideal for just about any application. Simply touch the tic tracer's tip to a terminal strip, outlet, or supply cord, and when the tip glows red, you know that voltage is present. Their compact design makes them easy to transport and keeps them readily available for use on a jobsite. Each tic tester gives you visual or audio indications of power detection and needs no contact with conductors to be activated. Compact Design: Pen-sized for easy transport and accessibility. Safety Features: Constructed of non-conductive polycarbonate for additional safety. Patents: Covered by one or more of the following patents: 6,828,767 5,103,165, UL 1436. Made in the USA: Ensuring quality and reliability. Ideal for use in: Service, maintenance, automotive, electricians, telecommunications, aviation, trucks/RVs, marine, industrial controls, and office equipment. Cable Certification: CAT III (UL), CAT IV (TUV). Outer Surface: Non-conductive body, probe, and cap composed of injected molded high-impact nonflammable polycarbonate, with a dielectric of 220 Volts AC potential at 60 Hertz. Operating Voltage: 50-1000 Volts AC. Operating Temperature: -20 C to +55 C. Circuit Board: Surface-mounted components on FR-4 substrate. Light Source: One high-intensity SMD LED for maximum illumination. Weight: 46.2 grams with batteries. Dimensions: 5.85 inches in length, 0.70 inches in width, 0.56 inches in height. Breakdown Voltage: 4000+ Volts AC. Operating Principle: This instrument senses the electrical field produced by AC voltage through insulation, without touching the conductor. A constant bright red glow with alternating sound will indicate the presence of AC voltage.
