The measurement interval defines, when a sensor does measurements. The default measurement interval is 5 minutes.

The logging interval defines, when the measured data is logged (meaning: measured data is combined into one block and the minimum, maximum, average,...  values of each sensor within this logging interval are calculated).  The default logging interval is 60 minutes.

Before each transfer, an additional logging event is triggered.

Each sensor chain (i.e. each input on the iMetos3.3 board) may have distinct measurement and logging intervals.
