Oscilloscope Function
Measures the voltage or amperage fluctuations of the vehicle’s sensor or actuator circuits in rapid
repetition and visualizes the signals in the graphic waveforms.
Measurement of cylinder compression is also possible by the use of optional pressure sensor.
The signal input ports of G-scan2 VMI module are assigned to specific measurement functions, so
please refer to the following table.
