Compression test

To start off the measurement, the compression can be checked using the HHT.

A mechanical fault may exist as from a speed difference of > 7 revolutions.

If the differences in speed are exceeded, a mechanical compression pressure test/cylinder gasket leakage test must be conducted on all cylinders to enable the fault to be precisely located.
