QDB4A QDB-5A Car Sensor Tester Oscilloscope PWM Drive Multimeter Ignition Injector Simulator Step Motor Driver Diagnostic Tool

Multi-Function Diagnostic Tool:

Combines oscilloscope for signal testing, PWM drive output for solenoids and injectors, stepper motor drive for idle and instrument motors, and signal simulation for sensors like air conditioner pressure and rail pressure; supports quick identification of automotive component issues.

Built-in Multimeter Capabilities:

Measures voltage (DC 0-30V), resistance (0-1MΩ), current (0-1.8A), capacitance (10nF-1000uF), and diodes; ideal for precise electrical checks without needing separate tools.

Adjustable PWM and Signal Output:

Features frequency range of 1-100kHz, duty cycle 0-100%, and VPP 1.25-14.5V; compatible with 2-wire and 3-wire modes for testing urea pumps, ignition coils, electronic fans, and flow sensors.
