Warning
Safety Information
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
two or less segments.
• 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.
Caution
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.

The Fluke Model 576 Infrared Thermometer (the
Introduction
thermometer) is for non-contact temperature
measurement. This thermometer determines
an object‘s surface temperature by measuring
the amount of infrared energy radiated by the
object‘s surface.

Using the Camera
In addition to the thermometer functionality the
Model 576 comes with a digital built-in camera
to documentate the measured places. The
pictures include the measured values and
additional information. the additional information
is customizable via the IRGraph software.
How to use the camera
1. To switch on the unit, pull the trigger.
2. Press the “Enter” button to activate the
camera while the display is active.
3. First the word “LOG” flashes and then the
camera icon appears.
The unit is ready to use now. It is preset to
take 26 high-resolution (640x480 pixel)
pictures.
4. Pull the trigger and hold it. The laser circle
shows where you are measuring.
5. Aim at the target. Be sure that the laser
sighting is inside the target.
6. Gently release the trigger to record the
photo and the temperature. Successful
recording of picture and temperature is
indicated by two short beeps and a green
blinking LED above the display. The next
location will be shown on the display.
Caution:
If you hear a longer beep and the LED
above the display is shining red, look at the
display. If you see “Use Flash!” and a flash
symbol, repeat your last measurement.
A green LED above the camera symbol

Spot Size
The measured spot size depends on the distance between the object you are measuring and
the infrared thermometer.
The relationship between distance and spot size
is 60:1(Standard Focus) or 50:1 (Close Focus) at
the focus point. The D:S in the far field (>33ft/
10m) is 35:1 (Standard) or 12:1 (Close Focus).
