Generally the curves will be linear or a slow start type of curve as often the speedo or tacho has a region at the
bottom where it doesn’t respond – eg tacho below 500rpm and speedo below 10km/h.
By setting the points appropriately the electronics will map to the markings to correctly display the value.
The sub range curve is useful to map a sensor - fuel or temperature that has a narrower range of variation to the full
meter range.
Known configurations can be found in the appendix.
As a starting point – just setting the max angle and maximum values and leaving the defaults for the rest should be
quite close to correct.
When setting these points – the gauge needle or the grap[hic meter will display the Y (output %) value as it is
adjusted.
AdcFilter
This is a setting that controls how the measured value is processed. For the most part the sensors will be set to RAW
or FILTERS 1s or FILTER 3. The Settings and behaviours are.
RAW :
No filtering or averaging is used – the latest measurement goes straight to the displays.
AVG 1s : The input value is averaged over a rolling 1s (10 samples)and the result goes to the displays.
AVG 3s : The input value is averaged over a rolling 3s (30 samples)and the result goes to the displays.
AVG 6s : The input value is averaged over a rolling 6s (60 samples)and the result goes to the displays.
PK_LOW_3s : The samples are passed through a fast attack slow decay filter to capture the lowest value hold it with
a slow decay: This is used to capture a pulsed sensor value where the minimum value needs to be measured - such
as a temperature sensor.
PK_LOW_6s : Same as above but with a 6s decay time.
PK_HIGH_3s : The samples are passed through a fast attack slow decay filter to capture the higest value hold it with
a slow decay: This is used to capture a pulsed sensor value where the maximum value needs to be measured .
PK_HIGH_6s : Same as above but with a 6s decay time.
