Product Details
✓Multifunction Electrical Tester：ATDIAG automotive circuit tracer, equipped with a transmitter and receiver, easily locates short circuits, open circuits, and wiring faults. By observing changes in the LED strip, you can determine whether the fault is a short circuit or an open circuit, without damaging the insulation. Suitable for professional electricians, maintenance technicians, and DIY enthusiasts. ⚠️Important: Designed only for 6–42V DC circuits. Do not use on AC power
✓Efficient Short Circuit Location: Circuit tester of a transmitter and a receiver. Flip the transmitter switch downward. A flashing red indicator signifies a short circuit. Turn on the receiver, which offers three adjustable sensitivity modes (switch to MODE3 when signal reception is poor). When in use, position the receiver perpendicular to the circuit. A beep accompanied by a red LED indicates the short circuit location has been pinpointed. In areas without short circuits, the receiver does not light up.This product delivers clear status alerts through dual audio-visual cues
✓Precise Circuit Breaker Finder: Flip the transmitter switch downward to energize. A flashing green indicator signifies an open circuit/break. Turn on the receiver and position it perpendicular to the wire under test. When the beep and green LED strip stop or show a distinct change, the open circuit location is indicated. In areas without breaks, the receiver's signal light will remain steady with a rapid beep. 🔌 Tip: After testing, disconnect the circuit first, then turn off the transmitter
✓Dual Audio-Visual Alerts: This product employs both audible and visual signals to deliver immediate, clear feedback. Audio tones and bright LED indicators adjust with signal strength, helping you quickly pinpoint faults. A low-battery warning flashes red when power is insufficient. Includes two 9V batteries for both receiver and transmitter. This is an efficient, precise circuit breaker finder tool
✓Continuity Function: ATDIAG electrical tester feature is only available on the transmitter. Switch the transmitter to CONT mode and connect the red and black clips to both ends of the wire. A lit green light indicates a good circuit condition; if it does not light up, it indicates a circuit fault. ✅ Remember: Slide the switch back to OFF after use
✓Superior Compatibility: DC voltage 6-42V automotive diagnostic tool, suitable for cars, pickup trucks, trucks, motorcycles, speedboats, RVs, excavators, and other equipment. Includes four different types of fuse plugs to meet your diverse needs.For any questions or concerns, please contact us at Atdiag@outlook.com
