Data logging interval and wind speed configuration

I read and re-read all I can find, but this is one subject I cannot get my mind around. At present I have 15 minute logging and have ticked “Use 10 min average wind speed” and “Use 'speed' for avg calculation”. If I change to 10 minute logging with the present settings, how will this affect wind speeds logged? Would it be best to un-tick one or both?

The logging interval and the wind speed calculation period aren't related in any way. The values that are logged are snapshots of the current values, irrespective of how they are calculated.

Hi Colin,

Don't untick only one. If you read the Help : Configuration : Station Settings carefully you will discover that unticking the "..average.." box has the same effect as unticking both, and unticking only "Use speed.." causes Cumulus to display and record the "average of peak wind speeds" which IMHO is a rather strange value to calculate.

Cheers, Alan.

Hi Steve Hi Alan

The pennys finally dropped and it now makes sense.

Thank you
