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.
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.
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.
