Since I did "REset Total Count" the ACPM value is wrong.
How do I reset the timer so that the ACPM value is again the correct average of my CPM readings?

The ACPM is calculated from (total Cont)divided by(total minute since power on).

Since reset total count only reset the count, not power on time. So the new ACPM will be (new total count)/(total minute since power on).

I think we need to define when the ACPM should be calculated.


So at the moment, ACPM is as good as useless unless you figured out what was going on and both reset the total and switched off and on again!!

I think it needs to be changed.

I think I have discovered the answer myself.
It seems that bizarrely if after changing the settings, I switch the unit off and on again I get more sensible ACPM results.
It's obviously a bug.

Please engage brain before answering.

Believe it or not, I'm not bothered about the value immediately following resetting total count, rather the values later on that are expected to have some meaning.

The A stands for average so ACPM should be the average of all CPM readings since some point in time.

It was this when I first switched the unit on from brand new but now it isn't, it's some meaningless lower value.
