-You will probably find it hard to find this section, but it is an important set of settings.
+You will probably find it hard to find this section as it is some way down on the Station settings web page, but it is an important set of settings.
-Around a dozen relate to the extent to which Cumulus uses information as provided by weather station and the extent to which Cumulus derives the information for itself in the format/formula it believes right. A few of these are each specific to particular weather station makes and relate to synchronising clocks in various ways. The rest relate to specific readings.
+Some offer choice from two options summarised in the table. The others are described below table.

+|Use bearing zero when calm
+|Reports bearing from weather station
+|Takes into account if wind is blowing, if it is not, the resting bearing is invalid
+|-
+|Calculate average wind speed
+|Use wind speed from weather station
+|Use rolling average of next selection to smooth out individual spikes
+|-
+|Use speed for average calculation
+|Use each 'latest' reading from weather station be it a gust or not for above calculation
+|Use the average wind speed output from weather station as input to rolling average above
+|-
+|Use 100% for 98% humidity
+|Report the humidity reading from station, even if station never reports 100%
+|Assume if station says 98 or 99, MX should report 100%
+|-
+|Calculate dew point
+|Use dew point from weather station (it can be calculated using lots of different formulae), if it is available
+|Use the formula MX has selected for calculating dew point (not same as Cumulus 1), select if weather station does not calculate dew point
+|-
+|Calculate wind chill
+|Use wind chill calculated by weather station (different formulas can be used)
+|Use the formula MX has selected for calculating wind chill (not same as Cumulus 1), select if weather station does not make its calculation available to MX
+|-
+|Synchronise station clock (DAVIS and INSTROMET only)
+|Don't worry if weather station clock gets out of sync with MX time.
+|Once a day try to ensure that weather station clock and MX time differ by less than 1 minute
+|-
+|Cumulus pressure trend names
+|Use what weather station reports as the pressure tendency
+|Let MX work out whether pressure is steady, rising/falling slowly, or rising/falling quickly, select if weather station does not make pressure trend information available
+|-
+|Davis VP 1-minute barometer update
+|Accept if weather station only updates pressure reading and trend information at quarter hour intervals
+|Force Davis station to update pressure reading and trend information every minute
+|-
+|Round wind speeds
+|Use wind speeds to the accuracy implied by the number of decimal places resulting from the conversion of reading from station to your chosen units
+|Express wind speeds in integers for your chosen units, rounding away decimal places resulting from unit conversion
+|-
+|Ignore LACROSSE clock
+|Use the time supplied by weather station when writing to standard log
+|Use the time supplied by device MX is running on when writing to standard log

 '''Extra Sensors''' - any sensors whose readings are logged in the standard log file are not '''extra'''. You tick here if you want Cumulus to log sensors using the extra sensors log file. Both log files are known as monthly logs in that a new log is created for each new month. (This is nothing to do with the '''special log''' that Cumulus 1 maintained for multiple temperature and humidity readings, as it is not available in MX).
