Situation
Possible cause and required actions
Non-stable RPM
readings
1. Wrong algorithm.
See above.
2. The signal is
overamplified.
See the III.2.
3. The power circuit is
susceptible to EMI.
Use proper NMEA 2000 data and
power cables and avoid routing near EMI sources.
Non-stable voltage
readings
1. The power circuit is susceptible to EMI.
Use
proper NMEA 2000 data and power cables and avoid
routing near EMI sources.
2. Non-stable output from
engine’s voltage regulator.
Increase damping setting
(Section VI.3).
