Milwaukee M12 TI - Manual (Page 8)

In the live thermal image in following fi gure, the 48.6 °C reading
at the top of the display is the temperature inside the center
target. The bottom of the display shows the color palette over
the temperature span (in this case, 30 to 50 °C). Span is
adjusted automatically in auto-range mode (default setting).
This manual explains how to use manual range settings under
“Custom Settings”.

MANUAL AUTO
When the display shows the object or scene framed the way
you want it, pull the trigger to take a thermal picture. The
display then presents you with choices to SAVE or CANCEL
the new image. See Figure.

To write the image to SD card, press the button on the
arrow keypad or pull the trigger again. Or, to discard the image,
press the arrow button to highlight CANCEL, then press the
button.
NOTE: Every minute, the Thermal Imager pauses to calibrate
its thermal sensor. You will hear clicking sounds. This is normal
behavior. The Thermal Imager does not respond to button
presses during calibration pauses.
USING THE BUILT-IN VISUAL IMAGE CAMERA
Every time you take a thermal picture, the Thermal Imager
captures a visual image at the same time. When you save a
thermal image, the Thermal Imager saves the visual image that
goes with it as well. Just like with thermal images, you can see
live visual images on the display. Press the button to
switch between thermal and visual images.
The fi gure shows a visual image as it would appear on the
display. This is the companion to the thermal image in previous
fi gure. There is no temperature data associated with a visual
image. Visual images are to help you identify objects in thermal
images.

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.
MANUAL RANGE AND AUTO RANGE
When you turn on the Thermal Imager, it is always in AUTO
RANGE mode. This means that it automatically selects the
lowest temperature and highest temperature in its range to
make thermal images. Usually, this produces the best results.
However, if you want to use a narrower or wider temperature
range, you can select MANUAL RANGE.
Typical reasons for selecting MANUAL RANGE:
An area in the fi eld 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.
There is one extremely hot point in the fi eld of view, and you
want to make sure that it gets measured. For this, you would
set a wider MANUAL range than AUTO RANGE.
There are both very cold and very hot objects in the fi eld 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.
To Set a MANUAL range, proceed as follows:
From live view mode, press
then select RANGE. .The
display appears as follows:

Press to select MANUAL range. The display appears as

Press and to experiment with the SPAN setting to choose
the best looking display for the area you are studying.
Press and to experiment with the LEVEL setting to choose
the best looking display for the area you are studying. When
you move the LEVEL, you shift the whole fi xed window of
temperature range up or down.
Press
to accept your custom LEVEL and SPAN settings and
remain in MANUAL range mode.
CHANGING THE COLOR PALETTE
IRON, RAINBOW and GREY are all shown in following fi gure.
IRON is the default. It is better at revealing small temperature
differences.

GRAY RAINBOW IRON
You can change to two other color palettes: RAINBOW and
GRAY. GRAY shows the most detail and is useful for record
keeping or reporting in formats that do not allow the use of
color. RAINBOW is an alternative to IRON, which uses more
colors. RAINBOW is better for show a very wide range of
temperatures because of the additional colors. To change the
color palette, proceed as follows:
From the live view mode, press
then if needed to select
COLOR, then . This opens the menu bar. Press the and
arrow buttons to make your selection, then press to confi rm
it.
TAKING A BASIC THERMAL PICTURE
Note: A SD card must be installed for the Thermal Imager to
save images and data. If no SD card is installed, you will see
the error message on the display: SD CARD MISSING.
Press and hold for 2.5 seconds until you see activity on the
display.
The Thermal Imager displays progress messages about Sensor
Calibration during warm-up. From Sleep Mode, warm-up is
almost instantaneous. Until warm-up is complete, button
presses are ignored.
Open the lens cap by pinching the buttons on the sides of the
lens cap. Flip it open until it snaps in place on top of the
Thermal Imager.
Observe the live thermal image on the display as shown in
following fi gure. Rotate the focus ring on the thermal sensor
lens for maximum sharpness. Make small focus adjustments
and wait for the image to settle before making another
adjustment. Focusing has a different feel than it does with
visual image cameras.
ENGLISH ENGLISH
The visual image camera has its own lens. It is fi xed-focus. (No
focus adjustment is necessary.) The visual image camera lens
is a small rectangular window below the lens, forward of and
above the trigger.
NOTE: If visual images ever seem to have poor quality, check
to see if this lens is dirty. Clean it gently with a camera lens
tissue moistened with camera lens cleaner fl uid.
Press
again to return to the thermal image view.
REVIEWING SAVED IMAGES
Press the button. This displays the most recent thermal
image. At any time during review, you can press to see its
companion visual image.
Press to continue reviewing the next older image. Press to
move to the next more recent images.
To return to live view, press
