*1 = Re-synchronizes once each day, to avoid reading memory at time of memory update
A Fine Offset station will be writing to its memory every 48 or 60 seconds (depending on model); Cumulus can attempt once a day to identify when this update of memory occurs, and thereafter try not to read the memory at update time, by using what is called a synchronisation mode of operation. See next parameter.

|FOReadAvoidPeriod=3
|Add this line to cumulus.ini [Station] section if you wish to change the default, this parameter used to fine-tune the previous parameter.
 
Sets the interval (in seconds) during each 48 (or 60 for some models) second of station logging period when Cumulus will avoid reading the station data to try and minimise lock ups. If the clock drifts more than this value in 24 hours, then Cumulus may cause the station to lock up when reading the data. The actual station clock drift gets logged to the diags file when the re-synchronise (see last parameter) takes place, this will give an idea of whether it would be useful to adjust this setting.
*3 = default value

*1 = reporting on (default)
Option to turn off reporting of 'lost sensor contact' for Fine Offset stations. (added Cumulus 1.9.4 b.1070)
 
|-
|EWdisablecheckinit=0
|Add this line to cumulus.ini [Station] section if application gets stuck when Cumulus starts up connected to a Fine Offset (clone) station (added Cumulus version 1.9.2, build 1011).
*0 = Disabled, default, it checks the first two bytes of the Fine Offset station's memory.
*1 = Ignores part of memory (see [[FAQ#When_I_start_Cumulus.2C_I_get_the_error_message_.22The_station_is_not_initialised.22]]).
 
 
|-
|EWduplicatecheck=0
|Add this line to cumulus.ini [Station] section if application gets stuck in the download stage.
Introduced in version 1.8.5 (b.630) to deal with certain bytes being given the same value in first and second line. For example one problem is that "55 AA" repeats at the start of the second line of data. Those bytes are only supposed to appear at the start of the first line (or so I am told).
*0 = Disabled, default, Cumulus accepts all bytes from the Fine Offset station's memory.
*1 = Ignores part of memory (see [http://sandaysoft.com/forum/viewtopic.php?f=13&t=393 this forum thread]).
For example one problem is that "55 AA" repeats at the start of the second line of data. Those bytes are only supposed to appear at the start of the first line (or so I am told).

|EWpressureoffset=x.y
|Add this line to cumulus.ini [Station] section
Got a pressure problem with a Fine Offset station when the pressure 'offset' that Cumulus reads is garbage, so Cumulus just uses zero? Tell Cumulus what offset to use, by using an external text editor to insert this parameter where x.y is the difference between your station (absolute) and sea-level (relative) pressures, in mb or hPa.

'''=== Spike Removal''' ===
* 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 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.
*The other 3 spike removal parameters have to be entered directly in cumulus.ini, none of these ones can be set on the 'calibration' screen.
Any ''changes in calculated value'', between one calculation and the next, greater than the value specified here will be ignored by Cumulus when it calculates the hourly rain total.
Cumulus ignores this parameter if the weather station directly supplies this figure to Cumulus. '''999''' is the default indicating no spike removal required.
 
|-
|EWmaxRainRate=999
A rain rate 'spike removal' filter, ''changes in calculated value'', between one calculation and the next, greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus when it calculates the rain rate.
Cumulus ignores this parameter for other makes of weather station (they supply a rain rate to Cumulus). The default value of '''999''' also effectively makes Cumulus ignore spike removal.
 
|-
|EWgustdiff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A wind gust 'spike removal' filter, ''changes in calculated value'' between one calculation and the next, greater than the value (always metres per second) specified here (with a default of '''999.0''') will be ignored by Cumulus.
 
|-
|EWwinddiff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu.. A wind speed 'spike removal' filter, ''changes in calculated value'' between one calculation and the next greater than the value (always metres per second) specified here (with a default of '''999.0''') will be ignored by Cumulus
 
|-
|EWpressurediff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A pressure change 'spike removal' filter, ''changes in read value'', from one reading to the next, off any station greater than the value (always mb) specified here (with a default of '''999.0''') will be ignored by Cumulus
 
|-
|EWminpressureMB=900
|Add this line to cumulus.ini [Station] section
Cumulus will ignore all pressure readings from the station that are less than this value (units are always hPa/millibars)
 
|-
|EWmaxpressureMB=1200
|Add this line to cumulus.ini [Station] section
Cumulus will ignore all pressure readings from the station that are greater than this value (units are always hPa/millibars).
 
|-
|EWTempdiff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A temperature change 'spike removal' filter.
Replace default of 999.0 with the maximum difference in degrees Celsius (the units Cumulus uses for all calculations regardless of what you select for display) you are prepared to accept between successive data readings.
 
|-
|EWhumiditydiff=999.0
|This is set in the spike removal frame on the Calibration settings screen off the configuration menu. A humidity change 'spike removal' filter, ''changes in read value'' from any station greater than the value (as %) specified here (with a default of '''999.0''') will be ignored by Cumulus.
