Mega Tester V4
The Mega Tester is the device to test the piezo injectors manufactured by Bosch, Siemens VDO, Denso. 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 by means of the injector control voltage to measure the stroke of the piezoelectric element. measure the gap between the piezo actuator and the pusher of injector hydraulic valve (from -2.0 µm till 15.0 µm).
