P100 Pro – Vehicle Electrical System Circuit Tester

The P100 Pro is a highly cost-effective and efficient automotive circuit diagnostic and analysis tester — a highly integrated, automotive-specific testing instrument. Designed for 9–30V vehicle electrical systems, it combines multiple diagnostic functions into one compact handheld device.

Key Functions

• Multimeter Mode– Quickly test DC voltage, resistance, diodes, and continuity in circuit systems. Displays Voltage (VDC), Resistance (OHM), and Diode/continuity (DIO) readings.
• Oscilloscope Mode– Displays the parameter curve diagram of the tested component, including voltage, frequency, time, and duty cycle (DIV, TIM, Vmin, Vmax, FRQ, DUTY).
• Battery Diagnostics (C-Tracer)– Multiple detection modes for more accurate data: Charging test, Startup test, Load test, Power output test.
• Component Activation– Generates activation signals for components such as lights, motors, and other on-board electronics. Supports MOMEN, LATCH, and PULSE modes with up to 18A CC value.
• Trailer Light Test– Accurate testing to eliminate safety hazards.
• Breakpoint Detection (Pathfinding)– Quickly detects the position of open conductors. Works with the P181 Wire Finder receiver to locate wire breakpoints by sending a sonic signal through the probe.
• 0–5V Adjustable Power Supply– Built-in adjustable voltage output for circuit testing.
• Frequency (Hertz) Measurement– Measures signal frequency in electrical circuits.
• Intelligent Voltage/Resistance Recognition– Automatically identifies circuit parameters.

Free Firmware Upgrade

Supports free online firmware updates (V6.10 operating system). Pathfinding and fault location features are available after upgrade. Download from the official website. (Pathfinding function requires use together with the P181 wire finder.)

Multi-Language Support

Supports English, Spanish, German, French, Italian, Portuguese, Polish, Russian, Vietnamese, Thai, Indonesian, Filipino, Malay, Arabic, Korean, Japanese, and many more languages.

Compatible Vehicle Types
