Infrared Thermometers
Introduction
The 566 and 568 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. The thermometers also support contact-
temperature measurement via K-type thermocouple. See the
Users Manual CD for complete operating instructions. Note that
the Japanese models indicate Celsius only.
Safety Information
WWarning
A Warning identifies conditions and actions that pose
hazards to the user. To avoid personal injury, follow
these guidelines:
•*Do not point laser directly at eye or indirectly
off reflective surfaces.
•Replace the batteries as soon as the low-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 or fire, know that
reflective objects may be much hotter than the
indicated temperature reading.
•Do not leave the thermometer on or near objects
of high temperature.
•Use of controls or adjustments or performance
of procedures other than those specified herein
may result in hazardous laser radiation
exposure.
•If the thermometer is used in a manner not
specified by the manufacturer, the protection
provided by the thermometer 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- for highest
accuracy, allow 30 minutes for thermometer to
stabilize before use).

Using the Thermometer
To take a temperature reading, point the Thermometer at the
desired object and pull the trigger. You can use the laser pointer
to help aim the Thermometer. You may also insert the K-type
thermocouple probe for contact measurement.
