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.)

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

Press the Laser ON/OFF
button to turn the laser

The object being
tested should be larger than the spot
size calculated by the field of view diagram
