Note
1) Refer to Easy manual for changing the Vertical division or Horizontal division.
2) Refer to Easy manual for triggering on a waveform.
Note
The oxygen sensor output voltage is used to control the fuel system air/fuel ratio. The output of
the sensor varies depending on the oxygen level sensed in the engine exhaust gases and the
operation of the closed loop fuel system.
