Indicators
(OL
and
‐
OL)
If
the
temperature
measurement
exceeds
1112°F
(600°C),
the
thermometer
will
display
OL
in
place
of
a
temperature
reading.
If
the
temperature
measurement
is
below
‐
58°F
(
‐
50°C),
the
thermometer
will
display
‐
OL
in
place
of
a
temperature
reading.
Locating
Hot
or
Cold
Spots
To
detect
a
hot
or
cold
spot,
aim
the
thermometer
at
a
region
beyond
the
target
and
then
scan
the
entire
region
in
a
slow,
up/down
motion.
Aim
the
laser
pointer
approximately
a
half
inch
below
the
point
of
test.
Distance
to
Spot
Ratio
(Field
of
View)
The
meter’s
field
of
view
is
12:1
(distance
to
spot
ratio).
For
example,
if
the
meter
is
24
inches
from
the
target
(spot),
the
diameter
of
the
target
must
be
at
least
2
inches.
Other
distances
are
shown
below
in
the
field
of
view
diagram.
Note
that
measurements
should
normally
be
made
<
2
feet
from
the
target.
The
meter
can
measure
from
further
distances
but
the
measurement
may
be
affected
by
external
sources
of
light.
In
addition,
the
spot
size
may
be
so
large
that
it
encompasses
surface
areas
not
intended
to
be
measured.
It
is
necessary
to
ensure
that
the
size
of
the
target
is
larger
than
the
spot
size.
The
smaller
the
target,
the
closer
the
distance
should
be.
See
the
accompanying
diagram.
