NB: The results of the tests might be influenced by a defective starter, flat battery etc.
Pressing "SAVE DATA" at the end of a test will allow the tests performed to be saved.
NB: If the tests performed before need to be displayed and examined, the tool does not have to be connected to the PC.

The data to analyse are not enough. A test lasts at least 6 seconds. This
warning is shown if the starting procedure is stopped before the amount of
time required to acquire data has elapsed.
Sometimes the result may be such that two "High" cylinders and two "Low"
cylinders alternate and the pairs of values are very similar. This situation is
reported as a special case, because it might be caused by a mechanical
part (e.g. pump) introducing a load, and thus more power absorption,
synchronized with two cylinders (once for each revolution of the engine).
A low-pressure cylinder results in lower power absorption for that cylinder
than in normal situations, during compression as in the other phases (descent
following compression, discharge and suction). This will have a nonuniform
impact on the compression of the other cylinders, thereby resulting in
differences in the measured power.
