About this item
- Smart Auto-Detection for Effortless Testing: This digital automotive circuit tester features a SMART mode that automatically detects DC voltage, polarity, resistance, and continuity as soon as the probe touches a power source or resistance. The device selects the optimal range for the most accurate readings, eliminating the need for manual adjustments. Simply press the hold button to lock and review the displayed values.
- Wide Voltage Range for Versatile Applications: With a 0.8V-100V DC detection range, this tester is perfect for diagnosing various vehicle electrical systems, including fuse testing, wiring inspection, battery checks, and ACC system diagnostics. Unlike standard testers that max out at 60V, our upgraded model supports up to 100V, providing a broader application scope. Additionally, it automatically identifies battery polarity, displaying a "-" symbol for negative terminals.
- High Accuracy for Reliable Results: Designed for precision, this automotive circuit tester offers 0.001V resolution for voltages under 2V and 0.1V resolution up to 100V. The resistance measurement spans 1Ω to 20MΩ, ensuring accurate diagnostics with an error margin of only ±1%. Whether you’re testing minor voltage fluctuations or large-scale electrical components, this tool delivers trustworthy readings.
- User-Friendly Features for Enhanced Efficiency: Equipped with a data hold function, the tester allows you to freeze readings for convenient recording. An integrated buzzer alerts you when resistance falls below 50Ω, while an “OL” warning appears on the display if the voltage exceeds 100V. The durable 78.74-inch PU spring wire ensures flexibility, and the large alligator clip allows one-handed operation for improved efficiency. The protective probe guard prevents accidental punctures while making the tool easy to store and carry.
- Bright LED Display & Reliable After-Sales Service: The high-contrast green LED backlit display ensures clear visibility in both bright daylight and dark environments, outperforming standard LCD screens. A built-in flashlight further enhances operation in low-light conditions. For added convenience, the tester comes with a storage bag for easy portability. We back our product with a 18-month warranty and lifetime technical support, ensuring long-term reliability and customer satisfaction.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
