For the sensor the following settings are available:
Write threshold (kmph)
– a new entry will only be created if the difference from the
previous value is bigger than the threshold.
Speed conversion coefficient (с)
– the coefficient that is used to converse amount of pulses
to a speed.
Frequency counter on the Р 2- Р 5 ports
Frequency inputs are used for the sensors which convert parameter change in frequency
change on its output. Examples are – fuel level sensors and temperature sensors.
Interpretation of the allowed parameters is equal to the analogue input (
Figure 66
).
Frequency sensors can be divided into the following categories:
«Frequency» – any sensor using the frequency output.
«Fuel level» – special filtration for the fuel level sensors.
«Engine speed» – tachometer connection.
