Key Features‌：

1. Smart Auto-Detection‌: Automatically identifies DC voltage (0.8V-100V), resistance (1Ω-20MΩ), continuity, and battery polarity without manual mode switching.

2. Data Hold Function‌: Freeze readings on the backlit LCD screen for accurate recording.

3. Polarity Detection‌: Displays “-” for negative terminals to prevent misjudgment during battery diagnostics.

Technical Specifications‌

1. Voltage Range‌: 0.8V-100V DC (resolution: 0.001V for <2V, 0.1V for 100V).

2. Resistance & Continuity‌:

•    Range: 1Ω-20MΩ (dual resolution: 1Ω-0.01MΩ for low resistance, 2000Ω-20MΩ for high resistance).

•    Audible alert for continuity (<50Ω).

     3. Safety Features‌:

•    Overvoltage warning (“OL” display for >100V input).

•    Insulated probe cover and anti-short design for safe operation.

Design & Usability‌

Backlit LCD + Flashlight‌: Clear visibility in dark environments (short press for backlight, long press for torch).

Portability‌: Compact size with storage pouch; auto power-off after 15 minutes.

Professional-Grade Accuracy‌: ±1% precision for automotive diagnostics (e.g., fuses, wiring, ACC systems).

Package Includes‌

1. 1x CP03 Tester

2. 1x Storage Bag

Applications‌

1. Vehicle Systems‌: Battery polarity checks, fuse testing, wiring diagnostics.

2. DIY & Professional Use‌: Suitable for home mechanics and workshop technicians.

Compatibility‌: Designed for 12V/24V automotive systems (not for AC voltage).
