measurement: you see the measured value but not the message “Add”.
b) 2
nd
measurement: you see the message “Add”. This means that the second
measurement is included in the calculation of the average; by pressing AVG you will
get also the average value calculated.

between the two values previously measured.
Press ESC to return back to the screen corresponding to the second measurement.
Upon returning back to the second measurement, press CLR if you want to cancel the
average value calculated and the corresponding counter.
