OBDResource CP03 Automotive Circuit Probe Tester, Smart Digital Voltage & Continuity Tester for 12V/24V Car Electrical Diagnostics

Smart Automotive Circuit Probe & Digital Voltage Tester

Product Overview

The OBDResource CP03 is a smart automotive circuit probe designed for fast and accurate electrical diagnostics in 12V and 24V vehicle systems. It automatically identifies DC voltage, polarity, resistance, and continuity, making it a reliable tool for quick troubleshooting and circuit checks on cars, trucks, motorcycles, and other vehicles.

Intelligent Signal Detection

The OBDResource CP03 smart circuit tester automatically recognizes the type of electrical signal when the probe touches the target circuit. It instantly detects DC voltage, polarity, resistance, and continuity without manual mode switching. Press the data hold button to lock the reading on the screen for easy viewing and recording while testing.

Wide Test Range for Automotive Systems

This power circuit probe tester features a wide detection range from 0.8V to 100V DC, making it suitable for a variety of vehicle circuit tests such as fuse checks, wiring inspections, battery system evaluation, ACC system testing, and accessory circuit checks. It also automatically identifies positive and negative battery terminals, with a negative sign displayed for reverse polarity readings.

High Accuracy and Detailed Measurements

The digital circuit tester offers high-resolution readings, with voltage resolution down to 0.001V under 2V and 0.1V under 100V, and resistance measurement ranges from 1Ω to 0.01MΩ. The overall measurement accuracy is approximately ±1%, ensuring dependable performance for everyday diagnostic tasks.

User-Friendly Design

The OBDResource smart circuit tester includes a data hold button that keeps the displayed reading visible after removing the probe from the circuit. A built-in buzzer alerts you when resistance is below 50Ω. If DC voltage exceeds 100V, the screen displays “OL” to indicate over-range conditions. The long spring lead includes a negative clip and probe head cover for safe operation and secure storage.

Backlight LCD Display and Flashlight Function

The voltage tester pen is equipped with a backlit LCD display and an integrated flashlight. Short press the light key to turn the screen backlight on or off, and long press to activate the flashlight for precise operation in dark or poorly lit environments. The included storage bag makes it convenient to store and transport the tool.
