introduction
Model 2260-21 M12™ 160x120 Thermal Imager is an
ultra-rugged, hand-held battery-powered tool that takes
thermal pictures, called “thermal images.” Thermal images
reveal different temperatures as different colors. A bright
color display shows an image of hot and cold spots and
temperature gradients in-between. The temperature of the
object in the center target is shown at the top of the thermal
image. Information about the temperature range and color
palette settings for the image are on the bottom of the
image. See Figure 1.
You can optionally load the thermal images onto a
computer to prepare a report later. The Thermal Imager
and its supplied PC software satisfy the requirements
of industrial electricians and technicians new to thermal
imaging, as well as expert professional thermographers.
174.3˚F
MILWAUKEE Thermal Imager Report Software is included
on the CD (Compact Disk). Instructions for using the
software are in the MILWAUKEE Thermal Imager Report
Software Manual, which is on the supplied CD.
With the software, you can organize, choose, annotate
and adjust images and present results in a report. In your
report, you can write recommendations and add your
company logo.

optimizing Thermal images
Once you become familiar with basic operation, you’re
ready to discover the image enhancement and refinement
you can achieve using custom settings. The custom setting
that has the most impact on temperature reading accuracy
is Emissivity. If you select only one custom setting, this is
the one to change. All the custom settings that affect the
accuracy of your data are:
•
Emissivity (default is 0.95 - rubber, asphalt, concrete,
black electrical tape) – Adjusts the Imager to
compensate for different target surface materials.
M12 160x120 Thermal Imager Operator's Manual
17
Download from Www.Somanuals.com. All Manuals Search And Download.
Emissivity is the ratio of a target surface’s infrared output
(radiance) to that of a blackbody at the same temperature.
A “blackbody” is a theoretical perfect radiator of infrared
radiation (IR).
Emissivity
Press , select SETUP, then press to get the Setup
Menu as shown in Figure 7. Press and as necessary
to select “EMISSIVITY.” This brings up the Emissivity Menu
as shown in Figure 11.
What this means is you can set the sensitivity of the
Thermal Imager to determine the true temperature of an
object, no matter what its IR radiation characteristics are.
The poorest radiators (surfaces with the lowest emissivity
ratios) need the most correction. These materials are things
like shiny metal and glass.
EMISSIVITY
0.95 DEFAULT
0.30 CUSTOM
When you have a low-emissivity surface that you need
a very accurate temperature reading from, placing black
electrical tape or even painting it with flat-black paint is
very effective. Black electrical tape and flat-black painted
surfaces have an emissivity ratio of 0.95.
MATERIAL
0.30 ALUMINUM
Figure 11. Emissivity Menu
WarninG
This setting tells the Thermal Imager what surface
material it is measuring. This is important, because
setting the right emissivity has a significant effect on the
accuracy of temperature readings. See Table 5 for a list
of the materials in the Thermal Imager Emissivity menu,
and their corresponding emissivity ratios. You can also
select “CUSTOM” in the emissivity menu, and select any
emissivity value. In Figure 11, “CUSTOM” shows “0.30,” but
when you select CUSTOM, you can choose any value.
To minimize the risk of electric shock, burn or
fire, never apply electrical tape or paint to an
electrically live surface. always check to ensure
the power has been turned off before touching a
surface.

Typical reasons for selecting MANUAL RANGE:
•
An area in the field of view that you want to focus on
has a narrow range of temperatures, and you want to
be able to resolve these small differences. For this,
you would set a narrower MANUAL range than AUTO
RANGE.
OIL (PETROLEUM)
PAINT
RUBBER
SAND
•
•
There is one extremely hot point in the field of view,
and you want to make sure that it gets measured. For
this, you would set a wider MANUAL range than AUTO
RANGE.
SOIL
STEEL
WATER
WOOD
There are both very cold and very hot objects in the
field of view, and you want to make sure to measure
both temperature extremes. For this, you would set a
wider MANUAL range than AUTO RANGE.

Glossary
Term
Definition
160x120
The number of pixels (picture elements or dots) in a saved thermal image. Each pixel has a
temperature associated with it. Each thermal image is 160 pixels wide by 120 pixels high.
accuracy
The guaranteed correctness of a temperature reading. For example, ± (2° or 2% of reading),
whichever is greater.
ambient temperature The surrounding background or environmental temperature around the Thermal Imager.
blackbody
A blackbody absorbs all thermal radiation striking it and emits all of it back. This means that a
perfect blackbody has an emissivity of exactly 1. Surfaces that are closest to a blackbody in
real world applications are flat black paint and black electrical tape. (See “emissivity.”)
battery fuel gauge
A symbol on the display in the shape of a battery, with a bargraph indicating the level of
remaining charge. The more white bars showing, the more charge remaining.
brightness level
Refers to the display brightness, which you can adjust in the Setup Menu.
calibrate, calibration
Comparing a measurement device’s readings to a reference standard. Calibration usually
involves adjustment to correct for errors, but not always. In the Thermal Imager, an internal
reference standard calibrates the unit once per minute. Also see “Calibration interval.”
calibration interval
The period of time after production or re-calibration that a measurement device’s
specifications are valid --1 year for the Thermal Imager. After 1 year, contact a MILWAUKEE
Service Center for factory calibration to renew the calibration cycle.
camera
Refers to the built-in visual image digital camera.
camera lens
Refers to the front optical element in the built-in visual digital image camera, located between
the flashlight LEDs below the Thermal Imager lens. This is a fixed-focus lens – no adjustment
required.

CD
Compact Disk. Also called a CD ROM, for CD Read-Only Memory. The CD supplied with the
Thermal Imager contains software and manuals.
Celsius
A temperature scale based on 0 °C as the freezing point of water and 100 °C as the boiling
point of water at a reference barometric pressure.
color palette, palette
A thermal image color scheme. Generally, black is the coldest and white is the hottest, but you
can choose the colors that represent the intermediate temperatures in the scale. Palette is one
of the Setup menu choices in the Thermal Imager: IRON, RAINBOW and GRAY.
detector
Also called “sensor,” the component that detects infrared radiation to determine temperatures.
The Thermal Imager’s detector is a microbolometer. (See “microbolometer” and “FPA.”)
detector, Infrared
A transducer element that converts incoming radiant infrared energy striking its surface into an
electrical signal.
directional keypad
display
The round group of arrow keys and center function key on the keypad.
The screen on the Thermal Imager that presents thermal or visual images and operating menu
choices.
emissivity (ε)
The ratio of infrared emitted by an object divided by infrared emitted from a blackbody at the
same temperature. The Thermal Imager allows you to select from a list of surface materials
to maximize accuracy of the temperature readings. This is called “adjustable emissivity.” (See
also “blackbody.”)
Fahrenheit
A temperature scale based on 32 °C as the freezing point of water and 212 °C as the boiling
point of water at a reference barometric pressure.
field of view (FOV)
Stated in angular degrees, the width and height of the area that the Thermal Imager senses all
incoming infrared energy to produce a thermal image.

fixed focus
An optical system for a camera or thermal imager that is set to one average distance, resulting
in an in-focus range that is not adjustable.
FPA (focal-plane
array)
A rectangular flat-panel matrix of detector elements on which the Thermal Imager’s optical
lenses and filters focus infrared energy to produce a thermal image. The type of FPA used in
the Thermal Imager is called a microbolometer. It produces signals that make a new complete
thermal image 60 times per second.
focal point
The distance from the lens at which the thermal imager is in focus.
focus distance
focusing ring
The closest distance at which you can focus the thermal image: 11.8 inches or 30 cm.
The movable ring around the front lens that you adjust for the sharpest thermal image. This
has no effect on the visual digital camera image.
frame rate
full scale
The number of times per second that the Thermal Imager displays a completely updated
thermal image: 60 times per second, or 60 Hz (Hertz).
The minimum temperature and the maximum temperature that the Thermal Imager can
measure. When in AUTO RANGE mode, the Thermal Imager adjusts itself to a portion of full
scale, called “span” that is somewhere within the full-scale endpoints. Using MANUAL RANGE
settings, you can set the Thermal Imager to cover full scale, but usually this makes it more
difficult to discern small temperature variations in the thermal image.
function key
image
The
button on the directional keypad. Its function changes depending on what activity is
happening. It is often used as the ENTER key to confirm a menu selection.
Either a thermal image or a visual image. The Thermal Imager captures both kinds every time
you pull the trigger. The pair of images are called an “image set.” When you save, erase, or
load an image to a PC, both the thermal and visual images always stay bundled together.

scale
Same as “thermal sensitivity.” The number of meaningful digits in a temperature reading, for
example, “10 °C, 10.1 °C, or 10.01 °C.” For the 10.01 °C reading, the resolution is “0.01 °C.”
An image written (recorded) onto the SD card installed in the Thermal Imager. Once saved,
images stay intact on the SD memory card when you turn off the Thermal Imager power.
The Thermal Imager uses your choice of two temperature scales: °C for Celsius or °F for
Fahrenheit.
SD Card
Removable, reusable flash memory storage cards commonly used in digital cameras. The
Thermal Imager accepts SD (up to 4 MB) and SDHC (for “High Capacity,” greater than 4 MB
up to 32 MB) SD cards. It does not accept mini-SD or micro-SD cards.

the same as auto power-off, which occurs after 20 minutes of no activity.
span
The width of the measurement window from the lowest measured temperature to the highest
measured temperature. The “Level” setting moves this window up or down in temperature.
spectral range
storage
The IR bandwidth, or longest to shortest infrared wavelengths that the Thermal Imager
detects.
Electronic memory (also called “Flash memory”) for saving the images and data created in
the Thermal Imager during a work session. The Thermal Imager uses a standard SD (Secure

Shorthand name for the M12 160x120 Thermal Imager.
thermal imager lens
The main lens on the Thermal Imager that has the hinged lens cap. This lens focuses infrared
radiation (IR) on the thermal sensor. There is another, smaller lens for taking visual digital
images.
thermal mass
Objects with low thermal mass revert to ambient temperature more quickly than objects with
low thermal mass. For example, a cast-iron engine block has higher thermal mass than an
aluminum one. Thermal mass and mass are not the same thing.
thermal radiation
Infrared emission from a target area. Thermal radiation intensity infrared radiation drops off
predictably with distance. This is why fixed-focus thermal imagers are less accurate than ones
you focus. Focusing tells the Thermal Imager how far away the target is, so the imager can do
the math to calculate the readings accordingly.
thermal sensitivity
thermal sensor
The smallest increment of temperature measurement resolved by the digital reading.
Equivalent to temperature resolution. (10 °C vs. 1 °C vs. 0.1 °C.)
Also called “detector,” or “sensor,” the component that detects temperatures throughout the
