Introduction
The Fluke Models 63, 66, and 68 Infrared Thermometers (“the
thermometers”) are for non-contact temperature measurement.
These thermometers determine an object’s surface temperature by
measuring the amount of infrared energy radiated by the object’s
surface. See Figure 2.

Safety Information
XW Warning
A Warning identifies conditions and actions that pose
hazards to the user. To avoid electrical shock or personal
injury, follow these guidelines:
•*Do not point laser directly at eye or indirectly off
reflective surfaces.
•Before using the thermometer inspect the case. Do not
use the thermometer if it appears damaged. Look for
cracks or missing plastic.
•Replace the batteries as soon as the battery indicator
( ) appears.
•Do not use the thermometer if it operates abnormally.
Protection may be impaired. When in doubt, have the
thermometer serviced.
•Do not operate the thermometer around explosive gas,
vapor, or dust.
•Do not connect the optional external probe to live
electrical circuits.
•To avoid a burn hazard, remember that highly reflective
objects will result in lower than actual temperature
measurements.
•Do not use in a manner not specified by this manual or
the protection supplied by the equipment may be
impaired.
WCaution
To avoid damaging the thermometer or the equipment
under test protect them from the following:
•EMF (electro-magnetic fields) from arc welders,
induction heaters, etc.
•Static electricity
•Thermal shock (caused by large or abrupt ambient
temperature changes - allow 30 minutes for
thermometer to stabilize before use).
•Do not leave the thermometer on or near objects of
high temperature.
