– HV oscilloscope measurement– secondary winding on a single cylinder
If you enter parameters for the twin-coil ignition with HV cables, two columns will be displayed in the bar chart of
the HV for one cylinder. If you setup the oscilloscope measurement, two HV courses will be displayed. One column
(course) corresponds to the measurement at the time of the firing to the “exhaust” and the second column (course)
corr
esponds to the measurement at the time of the firing to the “compression”.
5.4.4
ALL CYLINDERS MEASUREMENT
The oscilloscope is set to optimum values as a default.
Because the HV sensor allows the measurement of up to 4 cylinders at the same time, it is possible to display all
(max. 4) cylinders simultaneously. If you select this option, the following screen is displayed
– see Fig. 140.
The importance of columns is the same as with the single cylinder measurement. Individual columns are indicated
with the numbers of sensors.
