FEATURES
- Non-contact fault detection: Check for alternating magnetic pulse signals through automotive component housings without removing parts, piercing wires, or unplugging connectors. This non-contact design helps you quickly determine whether detectable signals are present and identify components that may need further troubleshooting.

-
Hall sensor with instant feedback: The built-in Hall chip senses changing magnetic fields produced by operating electromagnetic components. Internal circuitry amplifies and recognizes the pulse signals, triggering flashing indicator lights and a buzzer when detected. Without a detected pulse, these alerts remain inactive.

- Versatile automotive applications: Check magnetic pulse activity around ignition coils, fuel injectors, relays, solenoid valves, alternators, fan motors, and applicable Hall sensor systems. This multi-purpose testing pen helps you perform initial signal checks across different automotive electrical components before further diagnosis.

-
Dual sensitivity with automatic wake-up: Switch between low and high sensitivity modes to suit different testing situations. After 20 seconds without a detected signal, simply bring the tester near a component again. It automatically resumes testing when a signal is detected, reducing repeated manual operation.

- Built-in flashlight and portable design: The integrated LED flashlight illuminates components in dark engine compartments for more convenient inspection. Measuring 6.0 in / 15.2 cm long, the tester features a pocket clip for easy carrying and runs on two AAA batteries (not included).
