Multifunctional Automobile Circuit Tester TopDiag P200Pro Smart Hook Master Edition 9V-48V Car/Bike/Trucks Can Test/Cleaning Fuel Injector Circuit Analyzer

The TopDiag P200Pro Smart Hook Master Edition is a high-performance, multifunctional automotive circuit tester designed for 9V–48V electrical systems. It is an upgraded version of the standard P200, extending its support to higher-voltage vehicles like trucks and construction machinery while adding advanced features like leakage detection and enhanced fuel injector maintenance.

Key Features and Capabilities
Fuel Injector Analysis & Cleaning: Supports both online and offline testing. It can simulate injector signals (analog output), capture real-time signals, and perform cleaning modes to diagnose engine idling instability or high fuel consumption.
Leakage Current Test: A standout feature that detects real-time current magnitude, plots current waveforms, and can record data for up to one hour for later review.
Enhanced Multimeter & Oscilloscope: Measures DC voltage and diodes. The single-channel oscilloscope displays electrical waveforms for PWM, crank, and fan speed signals.
Component Activation: Capable of activating high-power components like motors and bulbs with instantaneous currents up to
Relay Testing: Includes a dedicated relay test box to quickly check 4-terminal and 5-terminal relays.

Power Supply: Offers an adjustable safe voltage output for testing sensitive ECU/PCM driver circuits and sensors.
