Details

Product Intro: The QDB-5A is a powerhouse multi-functional tester that replaces several individual diagnostic tools. Housed in a sleek unit with a TFT color screen, it integrates a digital oscilloscope, an advanced multimeter, and a highly capable signal generator and driver into one compact device.

Product Advantages: This device offers incredible versatility. It can drive PWM components (injectors, solenoid valves, electronic fans), operate stepper motors (idle speed motors, urea pumps), and simulate various sensor outputs (rail pressure, air flow). The built-in oscilloscope visually analyzes waveforms, while the multimeter handles current, resistance, voltage, diode, and capacitance measurements with precision.
Application Scenarios: Advanced automotive electrical troubleshooting, ECU signal simulation, actuator testing, and complex electronic component diagnostics in professional garages.
