INSTRUCTION MANUAL

Introduction

Congratulations on your purchase of the INF151 infrared thermometer.
Like all UEi products, we selected the features and functions of this
instrument to ensure that you’re getting the highest value possible.

Use the INF151 to make temperature measurements the fast, safe
and easy way. Its compact size lets you get into tight places while its
convenient laser targeting and high distance-to-spot ratio gives you
accurate readings on distant targets.

NOTE: The INF151 is not recommended for use on shiny surfaces such
as chrome, mirrors or polished metals.

To avoid thermal shock do not store the meter below freezing

Features include

• Precise non-contact measurements

• Switchable ˚C/˚F temperature units

• Automatic Data Hold

• Laser target pointer

Safety Notes

Before using this infrared thermometer, read all safety information
carefully. In this manual the word "WARNING" is used to indicate
conditions or actions that may pose physical hazards to the user. The
word "CAUTION" is used to indicate conditions or actions that may
damage this instrument.

Laser Sight

The INF151 is classified as a "Class II Laser Product" and is regulated
by the FDA

WARNING!

Using controls, making adjustments, or performing procedures
in any manner other than that specified herein may result in
hazardous radiation exposure.

• Class II laser products can cause injury if the beam makes
prolonged eye contact

• Do not point the laser toward the eyes or face of a person

or animal

• Laser's potential to cause damage is retained for hundreds

of feet

• Refer to the maintenance section of this manual in the event

of a laser failure

Safe Practices

This instrument is designed for professionals who know the hazards
associated with their trade. While this instrument offers no foreseeable
dangers beyond its laser sight, the equipment you are servicing, as well
as the environment you're working in, can be hazardous. These are a
few common safety practices for those working around temperature
critical environments:

• Follow the manufacturer's maintenance procedures when
servicing equipment

• Verify that an infrared thermometer is suitable for the type of
material you are measuring

• Before using this instrument to determine if an area is safe to

touch or enter, verify your readings are reasonably accurate by
comparison with known measurements

• Properly maintain your INF151 and calibrate it regularly
