QDB-PLUS Vehicle Actuator, Ignition Coil, Injector and Valve Tester

• Kawish QDB-PLUS is a multilingual, all-in-one automotive actuator test and diagnostic tool. It integrates an oscilloscope, a PWM signal generator, and a digital multimeter to troubleshoot and simulate vehicle electrical components without guesswork.

• Ignition Coils: Drives and tests independent, coil-type, and module-type ignition coils.

• Fuel Injectors: Supports 12V gasoline car injectors and 12V/24V diesel vehicle injectors.

• Stepping & Electric Motors: Tests idle speed stepper motors, instrument cluster motors, headlight steering motors, and urea pump motors.

• Solenoid Valves: Drives and checks duty-ratio-controlled solenoid valves and fuel metering valves.

• Power Supply: Operates on a 12V–24V DC input range with reverse-connection and overcurrent protection.

• Coil Driving Current: Adjustable from 0 to 3.5A.

• Frequency Range: Output frequency from 1Hz to 100kHz with a 1%–100% duty cycle adjustment.

• Sensor Simulation: Features Hall signal output with adjustable frequency, amplitude, and duty ratio to simulate duty-cycle sensors like air flow meters or A/C pressure sensors.

• Multimeter Capabilities: Includes built-in working current measurement, diode testing, and capacitance testing.
