Settings - High Low - High Low

In this section you see the current, highest, lowest and average value of all the sensors you have enabled for this section.

You also see the number of readouts, starting time, ending time (current time) and cpu speed

There are also 2 buttons. One will put everything to 0 and create a new log session and the other button will save the log. How and if the log is saved of course depends on the settings you have set in the High Low Settings section
