The GP-1 tester allows the generation of a PWM signal designed to test a wide range of components. The devices provide the opportunity:
– control of all kinds of solenoid control valves, commonly used in both gasoline and diesel engines (e.g., EGR valve, turbocharging pressure limiting valve, etc.) allowing to check their correct operation,
– Speed control of DC motors (DC motors),
– control of the fuel dose adjuster or ignition advance valve in fuel pumps used in diesel engines,
– and to control other devices using PWM signal, controlled by ground or supply voltage,
The PWM signal measurement module provides information on the frequency and filling of the measured signal. It is commonly used to analyze the correctness of control of components using PWM signals.
