Application
The OBDResource CP03 circuit tester incorporates a default smart measurement mode that automatically recognizes electrical signals- including DC voltage, polarity, resistance, and continuity—and displays results on the screen in real time, requiring no ma

Technical Parameter
1. Intelligent Automatic Detection FunctionFully Automatic Signal Recognition: In the default smart measurement mode, the probe automatically identifies measured signals (DC voltage, polarity, resistance, and continuity) upon contact with the power supply or resistance, eliminating the need for manual mode switching and ensuring minimal operation.Data Hold Function: Press the "Hold" button to lock the measured data on the screen for easy recording and reading, streamlining the testing process.2. Wide-Range Multifunctional TestingBroad Voltage Detection Range: Supports 0.8V–100V DC voltage testing, suitable for various vehicle circuit applications, including car fuse testing, wire diagnostics, battery analysis, and ACC system inspections.Automatic Polarity Detection: Instantly identifies the positive/negative terminals of the battery; a "-" symbol preceding the reading indicates negative polarity for intuitive and error-free diagnosis.Precision Resistance & Continuity Testing: Offers a resistance detection range of 1Ω–20MΩ, with resolutions of 0.001V (under 2V DC) and 0.1V (at 100V DC) for voltage, and resistance resolutions ranging from 1Ω–0.01MΩ (low resistance) to 2000Ω–20MΩ (high resistance). Accuracy is rated at ±1%, meeting professional-grade testing standards.3. Safety & Precision EngineeringReal-Time Alerts: A built-in buzzer triggers an alarm when resistance falls below 50Ω, while the screen displays "OL" for DC voltages exceeding 100V, providing instant warnings for abnormal conditions.Safe Operation Design: Features a long spring negative clip and a protective probe head cover, enabling one-handed operation and safe storage to prevent short circuits and ensure user safety.4. User-Centric Convenient DesignLow-Light Adaptability: Equipped with a backlit LCD display and a built-in flashlight, allowing clear readings and precise operations in dim environments. Short-press the light key to toggle the screen backlight; long-press to switch the flashlight on/off.Energy Efficiency & Portability: Auto-shuts off after 15 minutes of inactivity to conserve battery life. Includes a storage bag for easy transportation and secure storage when not in use.5. High Precision & Professional-Grade PerformanceVersatile Applications: Designed for comprehensive vehicle circuit maintenance, from basic fuse checks to complex system diagnostics, catering to both DIY enthusiasts and professional mechanics.Intuitive Feedback: Displays clear indicators (e.g., polarity "-", overvoltage "OL") and audible buzzer feedback, minimizing user error and enhancing troubleshooting efficiency.
