Features and Benefits:
More and more of today's vehicles are using Pulse Width Modulated (PWM) components. You can't simply test them by directly applying 12 volts anymore. This can cause misdiagnosis or worse, damage to the component. Power Pro supplies, measures and displays variable current using PWM just like today's vehicles. It's the only tester that can adjust the ouput percentage manually from 0%-100% in 1% increments to effectively pinpoint the cause of the failure.
