QDB-2A Car ignition coil lock motor solenoid valve fault detector driver generator Automotive Repair Tool

Ignition coil driving and testing: independent ignition, group ignition, coil type, module type, etc. Driving and testing fuel injectors: 12V injectors for gasoline cars, 12V24V injectors for diesel cars. Operate and test various types of solenoid valves (duty cycle control type), fuel metering valves, etc. Drive and test different types of duty cycle control motors, urea pump motors, etc. Drive and test idle speed stepper motor, instrument stepper motor, headlight steering stepper motor, etc. Output frequency, amplitude, duty cycle adjustable Hall signal, simulation of various types of duty cycle type sensors: air conditioning pressure sensor (duty cycle type), air flow meter (duty cycle type), etc. Operating power supply: 12v-24v, with polarity reversal and overcurrent protection. Solenoid coil drive current range: 0-3.5a Output frequency range: 1hz-100khz. Job cycle adjustment range: 1%-100% Adjustable voltage range: 1.3v-11.5v. Hall signal output voltage: 1.3-11.5v Important notes (please read before ordering): QDB-2A tester is only used as an auto repair tool and cannot be used to test/connect light bulbs/LED bulbs. Not an accurate 0%-100% pwm signal generator, the hall signal output is used to simulate car airflow meters, etc. That stepper motor signal is only used to test and check if the car's idle stepper motor is moving. Do not connect light bulbs/LED bulbs to the output terminals or short-circuit them to the output terminals. Cannot test Benz ignition coil and cannot test Porsche Cayenne 955 ignition coil.
