8.4 Very low / strong signal on measured values (linear / polar diagram,
bar graph)
If the measured values displayed are outside of the physical possibilities of the
engine, the problem must be examined in detail - error case!!
Some examples of different causes:
- External interference voltages in the measuring circuit (e.g. grounding of the
engine block / generator is bad)
- Wiring problems from the system itself
- the metal coupling can slip, which leads to incorrect speed values
- Interference voltages or grounding problems of the engine block or generator
disturb the measuring signal
- Error in the data line by wrong installation of the PC
The recording and interpretation of the signals over a longer period is important.
Changes of the signal could be evaluated based on the previous recorded data.
Based on these results suitable measures will derive.
