Averaging
Averaging
is
used
to
smooth
the
output
signal.
The
signal
is
smoothed
depending
on
the
defined
time
basis,
whereby
the
output
signal
tracks
the
detector
signal
with
significant
time
delay
but
noise
and
short
peaks
are
damped.
Use
a
longer
average
time
for
more
accurate
damping
behavior.
The
average
time
is
the
amount
of
time
the
output
signal
needs
to
reach
90%
magnitude
of
an
object
temperature
jump.

Attention:
The
disadvantage
of
averaging
is
the
time
delay
of
the
output
signal.
