Evaluation of Measurement Results
If the voltage is too low or too high, this implies a faulty ignition system or a faulty spark plug.
The voltage range which is correct for your ignition system can be found in the documentation
for your ignition system. It is advisable to carry out a reference measurement immediately after
installing the ignition system, in order to be able to compare subsequent measurements.

Shutdown
If you do not need the device for a longer period of time, remove the inserted batteries. To do so,
follow the instructions in the section

on page 30, but do not insert new
batteries.
