7) Logger variables
For each of the variables of the logger, one of the following functions can be selected:

AVG:
average value over the recording period,

MIN:
minimum value over the recording period,

MAX:
maximum value over the recording period.
8) Logger on variation
The variation mode of the logger is used to reduce the recording period for the data in the logger.
To do this, define the maximum variation percentage with regard to the previous recording. If the variation
measured is greater than this maximum, the recording is instantly triggered (no more than once per
second).
Comment: A percentage equal to 0% disables the associated value.
The following figure shows the reduction in the period of the logger when the flow experiences a variation:
The vertical lines (blue) correspond to the triggering of records of the logger. If the variation of the flow is
greater than the configured threshold, the logger forces a recording.
