SELECTING THE EMISSIVITY
Select the material or emissivity level in Settings .
1. Press the Settings button.
2. Use the arrow ▲▼ buttons to select EMISSIVITY.
3. Press OK.
4. Emissivity can be set by ratio or material. Use the arrow
◄► buttons to select the ratio column or the material
column. Then, use the arrow ▲▼ buttons to select the
desired ratio or material.
5. Press OK.
This setting tells the Thermal Imager what surface material it
is measuring. This is important, because setting the right
emissivity has a signifi cant effect on the accuracy of
temperature readings.
See the following table for a list of the materials in the
Thermal Imager Emissivity menu, and their corresponding
emissivity ratios.
ALUMINUM ......................0.30
ASPHALT .........................0.95
BRICK...............................0.83
CONCRETE .....................0.95
COPPER ..........................0.60
IRON .................................0.70
OIL (PETROLEUM) ..........0.94
PAINT ...............................0.93
RUBBER...........................0.95
SAND................................0.90
SOIL .................................0.92
STEEL ..............................0.80
WATER .............................0.93
WOOD ..............................0.94
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).
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.
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 fl at-black paint is very
effective. Black electrical tape and fl at-black painted
surfaces have an emissivity ratio of 0.95.
WARNING
To minimize the risk of electric shock, burn or fi re, 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.
OPTIMIZING THERMAL IMAGES
Use the emissivity settings, palette selection, and HOT/
COLD indicators to optimize your thermal images to your
needs.

SELECTING THE COLOR PALETTE
Select one of three color palettes to suit your needs.
Turn the tool on, then use the arrow ◄► buttons to step
through the palettes.
RAINBOW Shows a very wide range of
temperatures
IRON-BOW Useful for revealing small temperature
differences
HIGH CONTRAST Shows the most detail
HOT/COLD INDICATOR MARKS
To turn the HOT/COLD Indicator marks on or off while
taking a temperature measurement, press the OK button
during live view. Red (hot) and blue (cold) target marks
locate the highest and lowest temperatures in the display
area.
TAKING A TEMPERATURE MEASUREMENT
1. Insert a battery pack and turn on the tool.
2. Point the tool at the target. The Target Temperature is
displayed at the top of the screen.
3. To activate the laser guides, pull the trigger softly (less
than half-way). See "83:1 Distance to Spot Ratio".
4. Turn the HOT/COLD indicator marks on or off, or
toggle through the different palettes to get the desired
image on the display.
5. The center temperature is affected by the material of the
target, and can be adjusted by changing the Emissivity.
See "Selecting the Emissivity".
USING THE LASER INDICATORS
Use the lasers to frame up the target area. The lasers
correlate to the temperature crosshair on the display. Lasers
are accurate to 76 mm @ 1,30 m. The target temperature is
taken in between the laser indicators, and sized according
to the following chart.
415 mm
83 mm
ø 1 mm ø 5 mm
NOTE: A quick change in temperature (>12°C) can affect
the meter's readings. Always allow the meter to reach its
stable operating temperature after startup and before use (5
to 30 minutes, depending on environment).
TAKING A THERMAL IMAGE
An SDHC card must be installed for the Thermal Imager to
save images and data. If no SDHC card is installed, the
error message "NO SD CARD" is displayed.
1. Use the steps under "Taking a Temperature
Measurement" section to frame the desired image on
the display.
2. The Target Temperature, color palette, and any
displayed marks will be captured in the image.
3. Pull the trigger fully to take the picture.
4. To save the image, press the OK button or pull the
trigger again.
5. To cancel the image, use the arrow ◄► buttons to
select Cancel, then press the OK button.
IMAGE REVIEW
To review the saved images on the display:
1. Press the Image Review button.
2. Use the arrow ◄►buttons to scroll through the images.
3. To delete an image, press the OK button to select the
displayed image, then use the arrow ◄► buttons to
select Delete. Press the OK button again.
4. Use the DELETE ALL function in Settings to batch-
delete the images.
5. To return to live view, press the Image Review button
again.
MAINTENANCE
Always keep the camera lens clean.
Use only Milwaukee accessories and Milwaukee spare
parts. Should components need to be replaced which have
not been described, please contact one of our Milwaukee
service agents (see our list of guarantee/service addresses).
If needed, an exploded view of the tool can be ordered.
Please state the Article No. as well as the machine type
printed on the label and order the drawing at your local
service agents or directly at: Milwaukee Electric Tool,
Max-Eyth-Straße 10, D-71364 Winnenden, Germany.
