INFRARED THERMOMETER
WITH LASER SIGHTING
INTRODUCTION
This instrument is a portable easy to use 3½digit,
compact-sized digital infrared thermometer with laser
sighting designed for simple one hand operation. Meter
comes with Backlit LCD display, Auto-Hold function and
auto power down (10 seconds approx.) after releasing
Trigger to extend battery life.
SAFETY INFORMATION
It is recommended that you read the safety and operation
instructions before using the infrared thermometer.
CAUTION
• Do not use the unit near any device which generates
strong electromagnetic radiation or near a static
electrical charge, as these may cause errors.
• Do not use the unit where it may be exposed to
corrosive or explosive gases. The unit may be dam-
aged, or explosion may occur.
• Do not keep or use this unit in an environment where
it will be directly illuminated by sunshine, or where it
will be exposed to high temperatures, high humidity or
condensation. If you do, it may be deformed, its
insulation may be damaged, or it may no longer
function according to specification.
• Do not point the lens at the sun or at any other source
of strong light. If you do, the sensor may be damaged.
• Do not contact the lens against the object whose
temperature is to be measured, or get it dirty, allow it
to be scratched, or allow any foreign material to
adhere to it. Doing so may cause errors.
• Do not touch or hold by the front case. Temperature
reading can be affected by heat from hand.
• Do not place the meter on or around hot objects (70°C/
158°F). It may cause damage to the case.
• If the meter is exposed to significant changes in
ambient temperature (hot to cold or cold to hot). Allow
20 minutes for temperature stabilization, before tak-
ing measurement.
• Condensation may form on the lens when going from
a cold to hot environment-wait 10 minutes for conden
sation to dissipate before taking measurements.
• This unit is not constructed to be water proof or
dustproof, so do not use it in a very dusty environment
or in one where it will get wet.

DANGER
Pressing the Trigger turns the laser beam on and off.
Exercise extreme care and do not allow the laser beam
to enter your eye or those of any other person or animal.
• Do not look directly into the laser light from the optical
system.
• When measuring the temperature of an object which
has a mirror finish, be careful not to allow the laser
light beam to be reflected off the surface into your eyes
or those of another person.
• Do not allow the laser light beam to impinge upon any
gas which can explode.
EMC/RFI
Readings may be affected if the unit is operated within a
radio frequency electromagnetic field strength of approxi-
mately 9 volts per meter, but the performance of the
instrument will not be permanently affected.

OPERATING INSTRUCTIONS
Trigger
Pull the trigger to turn on the meter for measuring
temperature. Releasing trigger to stop measuring tem-
perature and automatically hold the display
reading, the meter power down automatically after 10
seconds.
Button function:
1. Set button
SET MODE & Numeric input key
"SET" annunciator appears when a numerical value can be
set ( during setting of
ε
, ALM Hi and ALM Lo).
key: The numerical value is increased.
key: The numerical value is reduced.
If either of these numerical value keys is held down, the
numerical value changes rapidly in the appropriate
direction.
The data will store in nonvolatile storage region while
after completing settings. In this mode the automatic power
-off feature is disable.
