As already mentioned, it is only MX where the 'Monthly Data Logs Viewer' screen will allow editing of values, but in both flavours you can use their viewer to look and see if you are happy with what has been recorded. | |||

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, but you know the value is not right for that particular time. | 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, but you know the value is not right for that particular time. | ||
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 | 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. In Cumulus MX you can do both of these in the data logs screen, in Cumulus 1 you will need to use an external editor. | ||
As explained above once any monthly log has been corrected, new highs and lows in other logs are easily rectified. | |||
