SAFETY RULES
CAUTION
This equipment is intended for use by
industry profes - sionals who know their
professional environments.
Temperature measurements are often
taken in poten- tially hazardous areas.
Know and use the safety stan - dards
prescribed by your profession.

8866 LASER SAFETY
Laser light can cause eye injury, if the
beam makes direct eye contact.
Reflected Laser light can also cause
damage, if a mirror or a glass-like
surface reflects the beam directly into
the eye.
Laser's potential to cause damage is
retained for hundreds of feet.
Use caution.
Do not point the laser toward the
eyes or face of a person or animal.
LASER SPLASH:
Indicates the use of laser equipment
and the category of laser used.

OPERATING INSTRUCTIONS
This instrument's light weight, pistol
grip design, raised push-buttons, and
large LCD display make it convenient
for most temperature measurement
needs and accessible to processes not
suited for conventional "contact"
temperature measurements.

TAKING MEASUREMENT SAMPLES
To take temperature measurements,
point the instrument at the surface to
be measured and pull the trigger.
A tube has been incorporated along the
top of the barrel to aid the user in
spotting the surface area to be
measured (target).
Although this simple explanation works
well in most cases, there are other
factors that may impact the
measurement accuracy.
Consider these influences before using
the data you obtain with your infrared
thermometer:
The target must completely fill the
spot diameter seen by the infrared
sensor, otherwise the temperature
displayed will be influenced by the
surface surrounding the target.
The ratio of the distance from the
end of the barrel to the size of the
spot being measured is 8:
1. For example, using the INF 8866,
an object that is 6" in diameter can
be accurately measured from 4'
away. When using the gun to find hot
-spots, accuracy of the reading is not
as important as keeping the gun at
the same distance from the target for
each sample measurement.
If you are looking for hot-spots on
electrical panels, for instance, you
