read
current
surface temperatures
in less
than a second.
Safely measure surface
temperatures
of hot or hard
to reach objects.
Any object
radiates infrared energy if
its
temperature
is
above
absolute zero.This energy
travels at the speed
of light in all directions.
An infrared thermometer lens
collecls and
focuses the infrared energy
onto a sensor.
The sensor
produces
a small
voltage output,
proportional
to the target temperature,
which is
processed
and
displayed.
The infrared thermometer should be
protected
from
the following:
O
Electro Magnetic Fields
(created
by arc welders,
induction
heaters and similar items.)
O
Thermal
Shock
(caused
by large or abrupt
ambient
temperature changes.
Allow 30 minutes for unit to
stabilize before
use.)
a
Do not leave the unit on or near objects
of high
temperature.

1) Pull and hold trigger
(laser
pointer
is
on as
default
setting) to turn on, LCD display
reading & battery
icon. Release
the trigger and the reading will hold
forapprox. l5secs.
2) Locating a
hot
spot:
Aim the thermometer outside
the area of interest. Scan across lhe
area in an up
and down motion until
the hot spot is located while
holding the activation trigger. The thermometer
will
continue to read the surface
temperature while the
activation trigger
is depressed.
Note
Holding the trigger should last about 1 second at
least
Fahrenheit & Celsius Conversion: Press the
"F/"c
button to switch from
Fahrenheit to
Celsius
readings.
Press the Laser ON/OFF
button to turn the laser
pointer
on
or off.
The object being
tested should be larger than the spot
size calculated by the field of view diagram
printed
in
this manual or on the unit itself

The farther the thermometer
is from the target,
the larger
the target area
will be. This relationship betvveen
distance
and target
size is normally expressed
as the distance
to spot, or
D:S ratio, At a distance of
8 feet, the
"target"
spot
would be 1 foot
in diameter. The thermometer
will
display the average
temperature across
the target area.

Most organic
materials and
painted
or oxidized
surfaces
have an emissivity of 0.95.This
unit is
preset
at 0.95.lnaccurate
readings will result
from
measuring shiny or
polished
metal suraces.To
compensate,cover
the surface
to be measured
with
masking tape
or flat black
paint.Measure
the tape or
painted
surface
when the area has
reached the same
temperature
as the
material underneath.
To clean
the lens : Blow off
loose
particles
using
clean
compressed air. Gently
brush remaining
debris away
with a moist cotton
cloth.
Do not
use
solvents to clean
the lens.
Do nol submerge
the unit under water.
