Localising any missing ignition pulses
Select the “kV” mode with the Mode select button to check which ignition pulse is absent.By positioning the test probe of the tester
next to an ignition cable (NO direct contact!), a capacitive coupling enables the tester to record the high-voltage ignition pulses and
simultaneously display a voltage value. Any missing cylinder can be localized by monitoring each ignition cable in this way.
Measuring the frequency of the high-voltage ignition pulses
Select the “Hc” mode with the Mode select button to change to the frequency mode.The tester can measure the frequency of the
ignition pulses. By positioning the test probe next to an ignition wire (NO direct testing), a capacitive coupling enables the tester to
record the ignition pulses and simultaneously display a frequency value.
Measuring technique 1: for each cylinder at the ignition cable
Measuring technique 2: ignition cable section of several cylinders
