• Modelis: QDB-4A

The Kawish QDB-4A diagnostic tester is a highly specialized, yet intuitive device designed specifically for garages and car services. It is used to precisely test and control electromechanical components in vehicles, allowing for lightning-fast location of faults. The equipment allows direct control of actuators such as fuel injectors, ignition coils, stepper motors and metering valves. With a wide range of 12-24V DC input power supply, PWM signal support and a built-in multimeter for voltage and resistance measurement, the QDB-4A is a comprehensive tool in the hands of every mechanic and electromechanical engineer.

The device is enclosed in a handy housing, which is ideal for a dynamic workshop environment. The central control panel is equipped with a clear LED indication system and a precise knob with a button function, allowing you to instantly change the tested values. A single press of the encoder allows you to increase parameters such as frequency or duty cycle by tens, and another by hundreds, which significantly speeds up the test configuration. The tester has separate operating modes for individual components of m.in. Step Motor TEST, PWM OUT, Valve TEST, reverse polarity protection for meter input and the ability to simulate operating signals of systems such as 3-wire urea pumps with frequencies from 150 Hz to 1 kHz.
