Mega Tester V4
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.
The operation of the
device is controlled from a computer using a keyboard and mouse. It is also
possible to start the device in manual mode using the buttons on the front
panel. Some functions will not be available from the instrument menu
