AVERAGE
The
AVG
function
mode
is useful for measuring a signal, which contains
ripple, noise or fluctuations Strictly speaking; this
AVG
function
is
diffe-
rent from the average
by
mathematical definition. More exactly it is a
smoothing
function,
which
reduces changes
due
to ripple or fluctuation
by
100 times from the following calculation:
AVG
= [sum of previous 100
data
measured] /
100
