==Correcting any logged data problems==
Some Weather stations may occasionally supply corrupted or rogue values to Cumulus. Cumulus provides via '''Configuration''' menu ''Calibration'' screen the ability to screen out spikes in data picked up from your weather station. See Cumulus help screen if you decide to use that to cope with future spikes. Some rogue values may be obviously invalid (e.g. a zero pressure), others (e.g. wind shake on a tipping bucket rain gauge on a fine day) may be within the accepted all-time range (so cannot be prevented by spike settings), but you know the value is not right for that particular time.
Frequently, the graphical views ('''View''' menu, ''Graphs'' or ''Select-A-Graph'' screens) are the best way to spot many rogue values and to help you guess by interpolation a more reasonable value. Another possiblity is to examine the relevant values in previous versions of the log files stored in the ''backup'' or ''backup/daily'' subdirectories of where your cumulus executable is stored. You may choose to just edit the rogue value into a reasonable value, or (if you are unable to decide on a better value) to delete that particular entire row in the monthly log. As explained above once the log is corrected, new highs and lows in other logs are easily rectified. The screen ''within Cumulus'' for viewing the monthly log does not allow editing of values.
