Mega Tester V3

View: 2759

The device Mega Tester V3 is a software and hardware complex that allows you to check Bosch and Siemens VDO injectors:

  • Measure the capacitance of the piezoelectric element;
  • Measure the resistance of the piezoelectric element under voltage;
  • Measures the insulation resistance under elevated voltage;
  • Continuous resistance measurement;
  • Form 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.
