Mega Tester V4

View: 4972

The Mega Tester device is a software and hardware complex that allows you to: measure the capacitance of the piezoelectric element, measure the resistance of the piezoelectric element under voltage, measure the insulation resistance under elevated voltage and also form the injector control voltage to measure the stroke of the piezoelectric element and the gap between the piezo actuator and the pusher of injector hydraulic valve. The functionality of the device allows you to assess the damage degree of the piezoelectric element and is intended to make it easier in diagnosis and troubleshooting of the piezoelectric injectors, as well as to help assess the correctness of the assembly of the injectors.
