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”.

48.6°C

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:

48.6°C

Press to select MANUAL range. The display appears as

follws (this example is using a different target image):

LEVEL SPAN

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.

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
