1. GETTING STARTED
1.1. Safety Precautions
Never aim the camera at the sun or other strong source of thermal radiation. This 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
artificial 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.
Do not point the camera’s laser pointer at a person's eyes. This can result in
burns and other damage to the eyes.
Caution! Observe all safety warnings! Use of controls or adjustments, or
performance of procedures, other than those specified herein, may result
in hazardous radiation exposure.
1.2. Battery Installation
The camera accepts four AA batteries, alkaline or NiMH
rechargeable. The latter can be recharged with an
external charger supplied with the camera.
When the batteries are removed, the internal clock has
sufficient 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:
www. .com [e-mail]1.800.561.8187

7
1.2.1. Battery Management
After the batteries are installed or replaced, the Battery management menu
appears when the camera first starts up. This menu can also be displayed by
pressing and holding down the F2 button when the camera is powered ON.
In the Battery management menu, the function buttons perform the following:
F1 confirms the information entered, closes the window, and initializes
the settings.
F2 edits and confirms entry of the selected item.
F3 cancels an entry or closes the window without resetting the battery
options.
The Battery management menu 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 icon only appears when battery power is low. When this icon 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 this icon appears yellow: . When
30 minutes of charge remains, this icon appears as .
To change mode, ensure the Advanced icon is selected. If not, use the arrow buttons to select it. Press to edit
the setting, and use the up and down buttons to change the setting to the desired option. Then press to
confirm the change.
Typeof batteries: The camera is delivered with low-self-discharge NiMH rechargeable batteries with a capacity of
approximately 2500mAh. These are the default parameters.
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.
1.3. Micro 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 to the left). If
this card is not installed, an error message appears when the camera
attempts to access it. This card is provided with the camera.
Before installation, the memory card must be formatted in one of the
following formats:

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

4. When the desired setting is displayed, press F2 .
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 brightness 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 to select it.
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 "media/sdcard/images."
It is good practice to organize records into several directories and limit 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 (a typical directory is shown
to the 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 by opening New. This displays the Create new directory
dialog (shown below):
www. .com [e-mail]1.800.561.8187

14
5. Select a letter using the buttons, and add it to the folder name by pressing F2 . You can also select
to insert the current date and time into the name. The name can be up to 20 characters long.
6. When the directory name is complete, save it by pressing F1 .
We recommend creating a directory in the root of the micro 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 color palettes that can be selected 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 Steel (black, purple, yellow to white),
Grayscale (black to white), and Rainbow (blue, green, yellow, to red). Steel is the default.
3. Select the desired palette and save it by pressing F2 .
www. .com [e-mail]1.800.561.8187

15
2. BASIC OPERATION
To display a thermal image (thermogram), ensure the camera’s lens flap is in the up position, uncovering 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 display area (see § 1.4.1.3). The displayed
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 (shown to the 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. Estimating Measurements Without a 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) / 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. Locating Hot and Cold Spots in an Image (MinMax)
The MinMax cursor option displays two cursors on the screen. One locks onto the location of the highest
temperature in the image, the other locks onto the lowest temperature. These minimum and maximum
temperatures are also displayed in the Measurements area of the screen.
www. .com [e-mail]1.800.561.8187

16
2.1.3. Measuring Temperature at a Point in the Image (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 up, down, left, and right directional buttons to display the temperature at
different points in the thermogram.
2.1.4. Measuring Temperatures of a Zone in the Image (Area)
The Area cursor option displays a square or rectangle on the screen, with the maximum and minimum
temperatures within the area also displayed. When you select this option, you can choose whether the area is a
square (default) or rectangle. Use the directional buttons to move the area on the screen. You can also resize the
area by pressing the up and left buttons simultaneously to reduce the size, or down and right to increase the size.
2.1.5. Displaying the Temperature Profile of a Line in the Image (Profile)
The Profile cursor option displays the temperature profile of a user-selectable 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. Displaying Points at the Same Temperature in an Image (Isotherm)
The Isotherm cursor option displays all points that fall within the same temperature range in the same color
within a certain tolerance. 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 are displayed in the selected color.
2.2. Freezing Palette Colors
By default, thermogram colors are calculated for each image (based on the highest and lowest temperatures 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 F2 or F3 when this button’s function is displayed as .

Press F1 in the Main screen and select Parameters. Then select the icon and choose the
Manual option.
Whenyou enter frozen palette mode, the minimum temperature displayed on the left end of the palette enters
edit mode for 2 seconds (highlighted in blue with the symbol) so you can increase or decrease this value
using 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 2 seconds. Use the up and down buttons to
increase or decrease this value. If you do not press a button within 2 seconds, edit mode is disabled.
To re-edit these values, press F3 when the icon is displayed (or select in the Parameters menu) to
enable edit mode for the minimum value.
To exit frozen palette mode, do one of the following:

Not in edit mode: press F2 or F3 twice while the icon is displayed.

Edit mode: Press F2 or F3 once while the icon is displayed.

Open the Parameters menu and select . Then select Automatic.

3. ADVANCED OPERATION WITH MORE PRECISE
MEASUREMENTS
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 Influencing Parameters
Measurements 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. Black electrical
tape has an emissivity of 0.95 and is suitable as a reference target.
The higher the relative humidity and the greater the distance, the larger the effect relative humidity has on the
measurement.
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 possible
measurement errors. In these situations, we recommend adjusting the camera settings to compensate for these
factors. These are set through the Target menu (see below).
Incorrect settings can produce results less accurate than results obtained with the 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 (shown to the left) lists default compensation settings for
target emissivity and distance, as well as for ambient humidity and
temperature.
You can use default settings for applications where high precision
measurements are not required, such as detecting a thermal bridge or
temperature difference.

3.2.2. Custom Compensation Settings
Influencing parameters should be adjusted from their defaults when:

Environmental conditions are significantly different from default settings for emissivity, relative humidity,
temperature, and distance

High measurement accuracy is required
To change these settings, select Influence in the Target menu and then press F2 . Ensure the setting is User; if
not use the up or down button to select this option. 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. Then press the up/down buttons to change it, and F2 to
save the change. After you save the emissivity value, it appears in the status bar. Allowable emissivity
values are from 1.00 to 0.05.
•Distance can be set from 1.6 to 3280ft (0.5 to 999.9m). Default is 6.6ft (2m).
•Humidity can be set from 0 to 100%. Default is 55%.
•Temperature can be set from 5° to +132°F (-15° to +55° C). Default is 55.5°F (13°C).
Note that you can also use measurement data provided by compatible Metrix ASYC IV Multimeters to
compensate for environmental factors (see §6.3.5). This requires connecting the meter to the camera via
Bluetooth (see § 6.3).
3.3. Tripod
To improve the sharpness and accuracy of the measurements, it is possible to use a tripod for image stabilization.
The camera can be mounted on a tripod equipped with a standard ¼-inch mounting head. 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 (see § 1.3), you can store and later recall the
displayed image and 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.PNG
…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 (yyyymmdd_hhmmss.PNG). 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 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 .PNG (for example
yyyymmdd_hhmmss_IR.WAV).
After you save an image, you can create copies of it (with palette changes, additions of cursors, and so on) by:
Saving the same frozen image multiple times
Recalling the original saved image from the camera’s memory and saving it again (see § 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 20181020_131254a_IR.PNG). 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. Note
that a visible image is not created for the derived file, since the visible image associated with the original file also
applies to the derived file.
When erasing visible images other than through the camera's file manager, take care not to create
“orphan” IR images for which no corresponding visible light image exists.
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 on 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 the trigger
function is Aim, press F2 to freeze the image and then press F3 . If the trigger function is Freeze,
press the trigger and then press F2 . In either case the displayed image is saved in the working
directory.

If the trigger function is 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 micro 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.

20
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. Vocal Message
4.3.1. Creating a Vocal Message
You can create a vocal message for the image. This requires a Bluetooth
headset connected to the camera (see § 6.2.1). The recording can be up to 30
seconds long. The vocal message 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 vocal message
(as shown on the left).
Press F2 to display the Record vocal screen, or F3 if you do not want to
record a vocal message.
In the Record vocal screen, F1, F2,and F3 perform the following functions:
starts recording
stops recording or playback
plays back the message
closes the window (without creating a file if the button is pressed before or
during the recording)
4.3.2. Changing the Vocal Message for an Existing Image
The only way to change a vocal message for an existing image is to create a new image file, add a new vocal
message, 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 vocal message.
5. Create the new recording.
6. Delete the original image (see § 4.5).
