Infrared Thermometers
Introduction
The 561, 566 and 568 Infrared Thermometers (“the
Thermometers” or “the Product”) 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.
Note that the Japanese models indicate Celsius only.
Safety Information
A Warning identifies conditions and actions that pose hazard(s)
to the user; A Caution identifies conditions and procedures that
could cause Product damage, equipment under test damage, or
permanent loss of data.
Symbols used on the Product and in this manual are explained
in Table 1 and Figures 1 and 2.

*WWarning
To prevent eye damage and personal injury:
•Read all safety Information before you use
the Product.
•Do not look directly into the laser with optical
tools (for example, binoculars, telescopes,
microscopes). Optical tools can focus the
laser and be dangerous to the eye.
•Do not look into the laser. Do not point laser
directly at persons or animals or indirectly off
reflective surfaces.
•Do not use laser viewing glasses as laser
protection glasses. Laser viewing glasses are
used only for better visibility of the laser in
bright light.
•Do not open the Product. The laser beam is
dangerous to eyes. Have the Product
repaired only through an approved technical
site.
•Replace the batteries when the low battery
indicator shows to prevent incorrect
measurements.
•The battery door must be closed and locked
before you operate the Product.
•Do not use the Product if it operates
incorrectly.
•Do not use the Product around explosive gas,
vapor, or in damp or wet environments.

•Do not connect the optional external probe to
live electrical circuits.
•See emissivity information for actual
temperatures. Reflective objects result in
lower than actual temperature
measurements. These objects pose a burn
hazard.
•Do not leave the Product 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.
•Use the Product only as specified, or the
protection supplied by the Product can be
compromised.
WCaution
To avoid damaging the Product 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 Product 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.
Changing Batteries
To change the batteries, see Figure 3.

Cable Connections (568 Only)
To connect the USB and Thermocouple to the 568, see Figure 4.

(568 Only)
Note
To prevent incorrect readings, do not perform a
temperature measurement of an earthed conductor while
the 568 is connected to a PC that is earthed by a three-
phase grounding plug.
561 Display
The primary temperature display reports the current or last IR
temperature read until the 7-second hold time elapses.
The secondary temperature display reports current
thermocouple temperature when a type-K thermocouple is
attached. See Figure 5.
