Measurement
Notes
1.
The
object
under
test
should
be
larger
than
the
spot
(target)
size
calculated
using
the
field
of
view
diagram.
2.
If
the
surface
of
the
object
under
test
is
covered
with
frost,
oil,
grime,
etc.,
clean
before
taking
measurements.
3.
If
an
object's
surface
is
highly
reflective
apply
masking
tape
or
flat
black
paint
to
the
surface
before
measuring.
4.
The
meter
cannot
make
accurate
measurements
through
transparent
surfaces
such
as
glass.
5.
Steam,
dust,
smoke,
etc.
can
obscure
measurements.
6.
The
meter
compensates
for
deviations
in
ambient
temperature.
It
can,
however,
take
up
to
30
minutes
for
the
meter
to
adjust
to
extremely
wide
ambient
temperature
changes.
7.
To
find
a
hot
spot,
aim
the
meter
outside
the
area
of
interest
then
scan
across
(in
an
up
and
down
motion)
until
the
hot
spot
is
located.
