Rainfall Calibration data removal

Brian
Have had to run a rainfall calibration on Davis rain gauge and I want to remove all calibration data from records … Where can I do it in one go. ??
Tried to use “Log / data file viewer/ Correct Data” screen but with no instruction / info it is VERY difficult to work out and make sense of it …

Is there a better way?? and what files are needed to be corrected …?

you can set your needed rain totals under
control panel
offsets and initial rain

for past day rain totals, I do have a youtube video detailing the steps

Brian
adjusted rain in control panel / Offsets & initial rain and set month total to zero [0.0] WD display “Month to Date” cleared to zero …BUT
When clicked on “yes” button to save settings that window closed and the original “Month to Date” [incorrect] value returned …
Closed pgm and restarted but still displays original incorrect value

Forgot to add

you need to click on set, next to each rain total (day, month, year)
then click on yes to save
