'''The Cumulus help file says''' - "The "Spike removal" section allows you to specify the maximum differences between successive readings that you wish to allow, for Fine Offset and La Crosse stations. If a reading differs from the previous reading by the value you specify, or more, then it will be ignored. Be careful in your choice of values; if the difference is genuine, (i.e. not a 'spike') and exceeds your supplied value, then that reading will be 'stuck' at the previous value until a new reading returns to within your supplied difference. | |||
Note that the spike removal values must be supplied in the 'native' units of the station, as shown on the screen. The gust value has no effect on La Crosse stations, as it only supplies one wind value - 'spike removal' is applied at the station level, unlike offsets and multipliers which are applied at a 'common' level; just use the 'wind speed' value." | |||

*7 of the 10 spike removal parameters listed below are adjusted in the frame at the bottom of the ''Calibration'' screen, off '''Configuration''' menu, they have a prefix of EW because they were introduced for dealing with problems seen in the Fine Offset family; the corrections are only applied when Cumulus 1 is reading directly from the station at a very frequent interval, spike removal does not apply when Cumulus is re-started and is transferring observations from the station logger to the Cumulus monthly log. | *7 of the 10 spike removal parameters listed below are adjusted in the frame at the bottom of the ''Calibration'' screen, off '''Configuration''' menu, they have a prefix of EW because they were introduced for dealing with problems seen in the Fine Offset family; the corrections are only applied when Cumulus 1 is reading directly from the station at a very frequent interval, spike removal does not apply when Cumulus is re-started and is transferring observations from the station logger to the Cumulus monthly log. | ||
