    We strongly recommend you to read the complete manual before using the equipment. If you already have experience with HEINZMANN systems you may only read the relevant chapters for the required information. It was our intention to structure this manual in a clear layout, to enable you to get easy and instant access to the information you are looking for.

  • Page 6: Description

    3 Description Description 3.1 Introduction The electronic indicator CPM 500 is a handy, battery powered, portable device to measure and evaluate cylinder pressure on diesel engines at speed up to 1500 RPM. The CPM 500 collects 10 consecutive pressure measure- ments (cycles) and calculates peak pressure and engine speed.
