1. GETTING STARTED
1.1. Safety Precautions
Never aim the camera at the sun or other strong source of thermal radiation.
Direct exposure to sunlight or other strong thermal radiation can impair camera operation and/or damage
its infrared sensor. To avoid accidental exposure, close the lens flap when the camera is not in use.
Avoid exposure to dust with the lens flap open.
Dust on the lens can absorb thermal flux and cause spurious diffusion. It can also degrade image
sharpness. To clean the lens, refer to § 9.2.
Do not touch the lens with your fingers.
Acids from human skin can damage the lens and its coatings.
Avoid jolting or dropping the camera.
1.2. Battery Installation
The camera accepts AA batteries of two types:
Alkaline
NiMH rechargeable
The latter must be recharged with an external charger.
When the batteries are removed, the internal clock has enough power for 15 hours. The
batteries are inserted through the end of the handle. Open the cover using a coin while
pressing down on the locking tab:
1.3. SD Memory Card Installation
Camera files (images, audio, and setup) are stored in the micro SD
memory card located on the left side of the head (see photo on left). If this
card is not installed, an error message appears when the camera attempts
to access it. (This card is provided with the product package.)
Before installation, the memory card must be formatted in one of the
following:

FAT16

FAT32
To insert the card, open the rubber flap and push the card into its slot. If the
card cannot be inserted, ensure that:

The card is facing in the correct direction

The card slot is empty

1.4.1.2. Image
The central part of the Main screen displays the image. This can be either infrared (thermogram) or visible light.
At the bottom of the image area is the color palette. This identifies the temperatures of colors in the thermogram.
By default, temperature/color assignment is performed automatically as a function of the minimum (black) and
maximum (red) temperatures detected in the image. In this mode the palette appears as follows:
You can also “freeze” the palette by defining minimum and maximum temperatures (see § 2.2). When the palette
is frozen, it appears as follows:

1.4.2. Battery Management If the batteries have been replaced, the Battery Management screen appears
when the camera starts up. This menu can also be displayed by pressing
and holding down the F2 button when the camera is powered ON.
In battery management mode, the function buttons perform the following:
F1 confirms the information entered, closes the window, and initializes
the battery manager with the settings.
F2 edits and confirms entry of the selected item.
F3 cancels an entry or closes the window without resetting the battery
manager.
The battery manager can operate in one of two modes:
Advanced Off (Default) is display-only; you cannot change any settings in this mode. In default mode, the
battery indicator only appears when battery power is low. When this indicator appears, the camera will
operate for approximately 30 minutes and then shut down automatically.
Advanced On allows more precise tracking of battery energy consumption, including the type of batteries used
and their estimated capacity. In Advanced mode, the battery icon indicates how much charge is left in the
batteries. Initially this icon is green: . When the remaining charge is low the icon appears yellow: . When
30 minutes of charge remains, the icon appears as it does in Default mode: .
If you consistently use the same set of rechargeable batteries, we recommend operating the camera
until it automatically switches off due to low batteries. This automatically recalculates and adjusts the
estimated capacity of the batteries. The new capacity is displayed by default the next time the Battery
management menu is displayed.
1.5. Configuring the Camera
When the camera is first started up, all parameters are set to their default values. You can modify these settings.
The changes can be stored in the camera’s memory; these settings will then be used every time the camera is
subsequently turned ON. Note that configuration settings can be saved in a Setup file. This file can then be
recalled and applied (see § 5).
To enter configuration mode, press F1 in the Main screen. This displays the Main configuration menu. The
Main configuration screen displays six options. Each option displays a submenu:

Display sets options that control how the display of data appears on
the camera screen.

Files displays options for storing, recalling, and working with images
and other files.

Setup saves and recalls configuration files.

Target sets parameters associated with the camera’s target, such as
distance and temperature.

Parametersconfigures camera settings such as language,
date/time, and others.

About displays information about the camera.
Use the camera’s arrow buttons to navigate through the menu options.
Selected options appear highlighted in yellow. (See Appendix A for the
camera’s complete configuration menu tree.)
10

In configuration mode, the function buttons perform the following:
F1 closes all open menus without action, and returns to the Main screen.
F2 either:

opens the corresponding sub-menu

(for editable settings) modifies the selected parameter
F3 closes the current window without action, and returns to the previous menu or screen.
When an editable parameter is selected, it appears on a blue background with the symbol to the left. This
symbol allows you to view available options, which you can scroll through using the up and down buttons. After
you select an option, press F2 to accept it.
Note that parameters that cannot be modified appear shaded.
1.5.1. Language

6. To edit a selected setting, press F2 and use the up and down buttons to change the setting.
7. Press F2 to save the setting.
Note that the Date/Time menu opens automatically at start-up if the power supply of the internal clock has been
interrupted.
11

1.5.3. Units of Measure (Temperature and Distance)
1. Open the Adjustments menu by pressing F1 in the Main screen and selecting Parameters >
Adjustments.
2. Select to display the units in which temperature and distance are displayed:

Temperature: Fahrenheit (°F) or Celsius (°C)

Distance: feet (ft) or meters (m)
3. Select the desired units and press F2 to save the settings.
1.5.4. Trigger Function
The camera trigger can be configured to perform different tasks when pressed.
1. Open the Adjustments menu by pressing F1 in the Main screen and selecting Parameters >
Adjustments.
2. Select Trigger to display the Trigger menu. This lists the following options.

Aim configures the trigger to toggle the display from the infrared image to the visible camera
image. When this option is selected, the TA icon is displayed in the status bar at the top of the screen.
When an image is recalled, the trigger is automatically assigned this function. When you exit the
recalled image, the user-selected function is restored.

Freeze configures the trigger to stop the continuous updating of the display and “freeze” the
image. Both the infrared and visible images are frozen; you can toggle between them by pressing F3.
When this option is selected, the TF icon is displayed in the status bar. Pressing the trigger again
restarts continuous acquisition.

Save configures the trigger to freeze the infrared and visible images, and then record them
on the micro SD card (if one is present). When this option is selected, the TS icon is displayed in the
status bar. Each press results in another save, creating derivative files if image acquisition is not
restarted between presses. To restart continuous acquisition, press F2 and then press F2 .
1.5.5. Automatic Camera Shutdown Time
To save battery power, the camera automatically turns OFF after a period of inactivity. The duration of this period
can be set to between 15 (default) and 60 minutes. This feature can also be disabled. To change this setting:
1. Open the Adjustments menu by pressing F1 in the Main screen and selecting Parameters >
Adjustments.
2. Select to display the shutdown time setting.
3. Use the up and down buttons to change settings. You can also select None to disable automatic shutdown.
When None is selected, the camera turns off only then battery power is too low to continue operation.
4. When the desired setting is displayed, press F2 .
12

1.5.6. Screen Brightness
You can adjust the screen brightness level to ensure good visibility in varying lighting conditions. By default, the
camera is configured in automatic mode: a luminosity sensor adjusts the lighting level at all times. To change this:
1. Open the Adjustments menu by pressing F1 in the Main screen and selecting Parameters >
Adjustments.
2. Select to display the screen brightness setting. Use the up and down buttons to change this setting.
Options are Automatic (the camera automatically adjusts the screen brightness), or a percentage of full
screen brightness (15%, 25%, 50%, 75%, or 100%).
3. When the desired setting is displayed, press F2 .
1.5.7. Image Storage Directory The working directory in which image files are stored must be located on the
micro SD card, which must be present in the camera. By default this is
"1:/images."
We suggest organizing records into several directories and limiting the number
of files in each. This will reduce the time needed to display the content of each
directory.
To change the working file storage directory:
1. Press F1 in the Main screen and select to display the Files
menu.
2. Select to display the Directory menu (left).
3. Use the up and down buttons to navigate through the listed folders. To
open a folder to browse subfolders, highlight it and press F2 .
4. You can select an existing folder as the working directory, or create a new one. To create a new folder,
open New. This displays the Create new directory dialog (see below):
5. Select a letter using the arrows, and add it with F2 . You can also select to insert the date and time.
The name can be up to 20 characters long.
6. When the directory name is complete, save it by pressing F1 .
13

We recommend creating a directory in the root of the SD card to store images. For FAT16 formatting, if
long names are used, only 256 entries are available in the root (any combination of 256 files and
directories). The card will therefore very quickly be considered full, even though its full capacity has not
been reached.
1.5.8. Color Palettes
The camera has three palettes of colors for displaying thermograms. To select a new palette:
1. Press F1 in the Main screen and select to open the Display menu.
2. Select to display a list of available palettes. Choices are Grayscale (black through white), Rainbow
(full-color spectrum), and Steel (black-purple-yellow-white).
3. Select the desired palette and save it by pressing F2 .
14

2. BASIC OPERATION
To display a thermal image (thermogram), ensure the camera’s lens flap is in the up position, exposing the IR
lens. Then turn ON the camera and point it at the target object. The thermogram appears in the camera’s main
screen (see § 1.4.1).
When default settings are in effect, to stop data acquisition and freeze the image on the display, press F2 .
When the image is frozen, the F2 button function becomes . Press this button to unfreeze the image and
resume data acquisition.
2.1. Measurement Cursor
Below the image is the Measurements area of the display (see § 1.4.1.3). The
displayed measurement data depends on the measurement cursor setting. By
default, no measurement cursor is selected, resulting in no measurement data
displayed in the screen. To change the cursor setting:
1. Press F1 in the Main screen and select to open the Display
menu.
2. Select to display the Cursor menu (left).
3. Select the desired cursor type. The following sections describe what
measurement data is displayed when each type of cursor is selected.
4. Save the cursor setting by pressing F2 .
2.1.1. No Measurement Cursor
By default, no measurement cursor is selected (the icon in the Cursor menu is highlighted). Note that even
with no displayed measurements, you can still estimate temperature from the color palette. The color distribution
between minimum and maximum palette temperatures is linear, so simply interpolating based on the position of
the color in the palette provides an estimated temperature.
For example, to estimate the temperature at a specific point in the thermogram, find the location of its color in the
palette. If the color appears to be in the center of the palette, the temperature is approximately:
Tmin + (Tmax – Tmin) * ½
or
(Tmin + Tmax) / 2
…in other words the mean of the minimum and maximum temperatures of the palette.
If the color lies in the 1st quartile:
Tmin + (Tmax - Tmin) /4
…and so on.
2.1.2. MinMax
The MinMax cursor option displays two cursors on the screen. One shows the location of the warmest spot
on the image, the other shows the coldest spot. These minimum and maximum temperatures are also displayed
in the Measurements area of the screen.
15

2.1.3. Point
The Point cursor option displays a single cursor along with the temperature at the current cursor location.
You can move the cursor with the directional buttons to display the temperature at different points in the
thermogram.
2.1.4. Square
The Square cursor option displays a square on the screen, with the maximum and minimum temperatures
detected within the square also displayed. Use the directional buttons to move the square on the screen. You can
also resize the square by pressing the up and left buttons simultaneously to reduce the size, or down and right to
increase the size.
2.1.5. Profile
The Profile cursor option displays the temperature profile of the horizontal line defined by the cursor on the
screen. The profile is displayed as a graph in the lower part of the screen. This cursor also identifies a point on
this line and indicates its temperature.
2.1.6. Isotherm
The Isotherm cursor option displays points that fall within the same temperature range in the same color.
When you choose this icon, you are prompted to choose the color (green, red, or brown) to display the points.
After you press F2 to save the color selection, the screen displays the thermogram. You are then prompted to
enter the reference temperature (via the up and down buttons) and tolerance size (via the left and right buttons).
Both the reference temperature and the temperature range (defined as ± the tolerance setting) are displayed at
the bottom of the screen. In addition, the palette graphically displays the temperature range. All points in the
image whose temperature falls within this defined range will be displayed in the selected color.
2.2. Freezing Palette Colors
By default, thermogram colors are recalculated for each image, based on the warmest and coldest spots in the
image, and assigned accordingly. As a result, the same color may not represent the same temperature in different
images.
You can “freeze” the palette to ensure each color represents the same temperature in all images. When the
palette is frozen, a red padlock appears on the palette. The minimum and maximum values are also displayed in
red.
To enter frozen palette mode, do either of the following:

Press F3 when its function is displayed as .

Press F1 in the Main screen and select Parameters. Then select the icon and choose the option
Manual.
When you enter frozen palette mode, the minimum temperature setting on the left end of the palette enters edit
mode for a few seconds (highlighted in blue with the symbol) so you can modify this setting via the up and
down buttons.
To modify the maximum temperature setting, press the right button when the minimum setting is in edit mode.
This highlights the maximum value, which remains in edit mode for several seconds. Use the up and down
buttons to change the value. If there is no action on the keypad for a few seconds, edit mode terminates.
To change the minimum or maximum palette temperature value, pressing F3 with the icon displayed (or
selecting in the Parameters menu) returns the minimum value to edit mode.
To exit frozen palette mode, do one of the following:

Not in edit mode: press F3 twice while the icon is displayed.

Edit mode: Press F3 once while the icon is displayed.

Open the Parameters menu and select . Then select Automatic.
16

3. ADVANCED OPERATION
3.1. Best Practices

Make the measurement in the central zone of the screen.

Aim straight on, not at an angle.

Measure targets that are as large as possible. Avoid point-like targets.

If the ambient temperature changes significantly, allow the camera to stabilize.

If batteries have warmed up during charging, wait for them to cool down to ambient before putting them
back in the camera.
3.2. Compensating for Environmental Factors
The flux received by the camera can be influenced by:

emissivity of the target object

temperature of the environment

distance to the target

relative humidity of the air
Emissivity is the most crucial factor. This defines the efficiency with which a material radiates infrared energy.
Different materials have different emissivity values. A perfect “blackbody” has an emissivity of 1.00 (the
theoretical maximum), while a material that emits no infrared energy has an emissivity of 0.00.
The higher the relative humidity and the greater the distance, the larger the relative humidity influence is.
The relative humidity, ambient temperature, and distance are likely to vary more significantly outdoors.
The camera default settings may not be suitable for the present environmental factors, resulting in significant
measurement errors. In these situations, we recommend adjusting the camera settings that compensate for
these factors. These are set through the Target menu (see below).
Incorrect settings can produce inaccurate results that may be less reliable than using default
settings.
3.2.1. Default Compensation Settings
Compensation settings are managed through the Target menu. To display this
menu, press F1 in the Main screen and select Target .
The Target menu (left) lists default compensation settings for target emissivity
and distance, as well as for ambient humidity and temperature.
If the distance and emissivity of the object being observed and current
environmental factors closely match these settings, the parameters cannot be
customized and appear shaded in the Target menu. Also, the emissivity
correction setting in the status bar appears as . In this situation, the default
compensation settings are used for all calculations performed by the camera.
You can use default settings for applications where high precision
measurements are not required, such as detecting a thermal bridge or
temperature difference.
17

3.2.2. Custom Compensation Settings
Environmental settings should be adjusted from their defaults when:

Environmental conditions are significantly different from default settings for emissivity and relative
humidity

High measurement accuracy is required
To change these settings, select Influence in the Target menu and then press
F2 . Then use the up or down button to change the setting to User. This
enables you to change the following parameters:

Emissivity: Choose from a list of materials or enter a value. You can
modify three “user” values by pressing the right button to enter the
value, the up/down buttons to change it, and F2 to save. After you
save the emissivity value, it appears in the status bar. Allowable
emissivity values are 1.00 to 0.05.

Distance can be set from 0.5 to 999.9m (1.6 to 3280’). Default is 2m
(6.6’).

Humidity can be set from 0 to 100%. Default is 55%.

Temperature can be set from -15° to +55°C (5° to +132°F). Default is
25°C (77°F).
Note that you can also use measurement data provided by peripherals to compensate for environmental factors.
This requires connecting the peripherals to the camera via Bluetooth. For information about connecting a
peripheral and using its measurement data for environmental compensation, see § 6.3.
3.3. Tripod
The camera can be mounted on a tripod equipped with a standard ¼-inch mounting head. This provides more
stability than can usually be achieved via hand-held photography.
Attach the camera to the tripod by screwing the tripod mounting screw into the threaded receptacle in the battery
compartment cover on the base of the camera handle (see below).

4. SAVING AND RECALLING IMAGES
When the micro SD memory card is inserted into the camera, you can store and later recall the current image and
displayed measurements.
4.1. Image Files
4.1.1. Naming Conventions
The camera has two objective lenses, one for infrared images and the other for visible light images. When an
image is saved, two files are created. The infrared image is saved using the filename convention:
yyyymmdd_hhmmss_IR.BMP
…where “yyyymmdd_hhmmss” is the date and time the image was acquired. The visible image is saved using
the same naming convention, but without the “IR” designation. This naming convention requires accurate
date/time settings (see § 1.5.2).
An audio file can also be included with the two images. This allows you to record a description and other
information relevant to the images. This requires a Bluetooth headset to be connected to the camera (see § 6.2).
This file is given the same name as the associated IR image, with the extension .WAV instead of .BMP (for
example yyyymmdd_hhmmss_IR.WAV).
After you save an image, you can create copies of it by:
Saving the same frozen image multiple times
Recalling the original saved image from the camera’s memory and saving it again (§ 4.4.1)
These copies are called “derived” images. To differentiate derived image files (which all have the same date of
acquisition) an index letter is added after the date (for instance 20141020_131254a_IR.BMP). When all letters
from "a" to "z" have been used, the letter "z" is re-used and the existing file with this name is overwritten.
When erasing visible images other than via the camera's file manager, take care not to create “orphan”
IR images.
4.1.2. Directories
Image files are saved in the working directory defined in the Directory menu (see § 1.5.7). The working directory
must be located in the micro SD card installed in the camera. If the card is missing, an error message appears
when you attempt to save an image.
4.2. Saving an Image
You can save an image when a micro SD memory card is inserted into the camera. To save a new image file:

If the trigger function setting is Aim or Freeze (see § 1.5.4), you must first stop acquisition. If trigger
function = Aim, press F2 to freeze the image and then press F3 . If trigger function = Freeze, press
the trigger and then press F2 . In either case the current image is saved in the working directory.

If the trigger function is set to Save, each press freezes the image (if it is not already frozen) and saves it
in memory. When the file has been saved to the SD card, a message displays the name
of the file that has just been created (see the example on left).
If acquisition is stopped, each additional press of the trigger creates a new
"derived" image (same date of acquisition), differentiated by an index letter
added to its name (see § 4.1).
In addition, you can create a new derived image from a recalled image, as
explained in § 4.4.1.
19

Depending on the situation, 1, 2, or 3 files are saved:
1 file is created when you save a derived image with no headset connected. The visible image associated with
the derived image already exists, so only an IR file is created.
2 files are created when saving:
An original file with no headset attached (the IR image and its visible image).
A derived image with a headset attached, and you create a voice recording (§ 4.3) for the derived image.
3 files are created when you save a new image with the headset attached, and you create a voice recording (IR
image, visible image, and voice).
4.3. Voice Recording
4.3.1. Creating a Voice Recording
You can create a voice recording to be associated with the image. This requires
a Bluetooth headset to be connected to the camera (see § 6.2.1). The
recording can be up to 30 seconds long.
The voice recording can be added only after you have created the image file.
After the message appears displaying the name of the new file, if the headset
is connected another message prompts you to record a voice message (left).
Press F2 to display the Record vocal screen.
In the Record vocal screen, F1, F2,and F3 perform the following functions:
start recording (or adding another message)
stop recording or playback
play back the message
close the window (without creating a file if the button is pressed before or
during the recording)
4.3.2. Changing the Voice Recording for an Existing Image
The only way to change a voice recording for an existing image is to create a new image file, add a new voice
recording, and delete the old image file. To do this, ensure the headset is connected to the camera. Then proceed
as follows: 1. Recall the image (see § 4.4).
2. Press F1 to display the Recall menu (left).
3. Select Save in the Recall menu. A new derived image (with a new
index letter) is created (see § 4.4.1).
4. After you confirm the save, a message prompts you to create an
associated voice recording.
5. Create the new recording.
6. Delete the original image (see § 4.5).
