- Page 2 ATTENTION An infrared camera is a sensitive optical measuring device. Pay special attention to the following points: Never aim the camera towards the sun or other source of intense thermal radiation (e.g. welding, cutting, and similar operations). If parts of the camera are damaged or present problems following failure to heed the warnings listed above, neither the manufacturer nor the distributor shall be held liable, and all costs incurred shall be borne solely by the operator.

Page 5: Getting Started
1. GETTING STARTED 1.1. Elementary precautions 1.1.1. Never aim the camera towards the sun or other source of intense thermal radiation Direct exposure to sunlight or other strong thermal radiation can impair the operation of the camera and make the infrared sensor partially or totally inoperative for as long as several months. -
Page 6: Powering The Camera
1.2. Powering the camera The camera accepts AA batteries of two types: - either alkaline batteries - or Ni-MH rechargeable batteries. The latter must be recharged with an external charger. When the batteries are withdrawn, the internal clock has enough power for 15 hours. -

Page 11: Displaying The Menus
1.4.3. Displaying the menus The menus are accessed by pressing the F1 key with the function . When a menu is displayed, new functions are assigned to the F1, F2 and F3 keys. Select an item in the menu using the arrow keys. The selected items appear in yellow. -
Page 12: Changing The Units Of Temperature And Of Distance
1.5.3. Changing the units of temperature and of distance From the Main/Parameters/Adjustments menu, validate the item opposite to select the unit in which temperatures or distances are displayed: -the temperature is displayed in degrees Fahrenheit (°F) or Celsius (°C), -the distance in feet (ft) or metres (m). 1.5.4. -
Page 13: Changing The Image Backup Location
1.5.7. Changing the image backup location The images are saved to a working directory which can be selected by the operator in the Main/Files menu, by validating the item opposite. The working directory must be located on the micro SD card, which must be present in the device. -
Page 14: Measurement Campaign
2. MEASUREMENT CAMPAIGN By default, no measurement cursor is selected (selection of the item in the Main/Display/Cursor menu), and the camera produces only infrared images. 2.1. Estimating the temperature of an object without a cursor It is possible to evaluate a temperature from the information of the colour palette. The distribution of the colours between the minimum and maximum temperatures displayed at the ends of the palette is linear, so simply interpolating based on the position of the colour in the palette gives the temperature sought. -
Page 15: Displaying Points At The Same Temperature In The Image
2.6. Displaying points at the same temperature in the image In the Main/Display/Cursor menu, choose the Isothermal cursor it marks with another palette of colours the points at the same temperature to within a given tolerance. Selection of this mode requires two validations of the menu item with the F2 key: one to activate selection of the colour representing the temperature (Up/Down keys to scroll through the colours) and one to validate the choice and start the function). -
Page 16: More Precise Measurement Campaign
3. MORE PRECISE MEASUREMENT CAMPAIGN 3.1. Good practices Make the measurement in the central zone of the screen. Aim head on, not at an angle. Measure scenes that are large enough. Avoid point-like scenes. Following a variation of ambient temperature, wait for the camera to stabilize. ... -
Page 17: Using The User Compensation For The Influencing Factors
3.2.2. Using the user compensation for the influencing factors This calculation mode is necessary when the measurement conditions are significantly different from the calibration conditions (emissivity, relative humidity) and the operator wants accuracy. When user compensation is selected, the various parameters can be adjusted: emissivity: it is necessary to choose from a list of materials or enter a value. -
Page 18: Saving And Recalling Images
4. SAVING AND RECALLING IMAGES If there is a micro SD memory card in the drive, it is possible to store, then recall the current image and measurements displayed. 4.1. How are the image files named? The camera has two objectives, one for infrared images, the other for entering a photograph in the visible domain. In consequence, when image... -
Page 19: Where Are The Images Saved
As the case may be, 1, 2, or 3 files are saved: 1 file for a derived image (same date of acquisition) with no headset connected (the visible image already exists, only the IR file is created) 2 files for the creation of an image from a new acquisition (new date of acquisition) with no headset connected (the IR and visible image files are created) 3 files for the creation of an image from a new acquisition with a vocal file... -
Page 20: Recalling An Image
4.6. Recalling an image An image is recalled from the Main/Files/Images menu, provided that the micro SD card is in its slot. The file manager lists only infrared images generated by the camera bearing a name in the form yyyymmdd_hhmmssX_IR.PNG, along with the folders, to allow browsing in the tree of the SD card. -
Page 21: Playing Back A Vocal Remark
4.7. Playing back a vocal remark A vocal message is played back using the Bluetooth headset, which must be connected to the camera (see § 6.2.2. How to connect a headset). To play back the vocal message associated with an image, the image must be recalled (see §... -
Page 22: Via The Usb Cable
4.9.2. Via the USB cable • The camera, in normal operation, has a USB port of the type used for mass storage: when the camera is connected to the PC by the USB cord, the content of the micro SD memory card can be accessed directly by the PC; the image is transferred by cut or copy and paste from one folder to another. -
Page 23: Backup And Recall Of User Configurations
5. BACKUP AND RECALL OF USER CONFIGURATIONS The setup files contain a complete backup of the current parameters of the camera, enabling the operator to return to an operating mode defined earlier (user setup) or to a predefined setup (factory setup). The setup stores the list of Bluetooth peripherals connected and their statuses, to allow their re-use. -
Page 24: Deleting A Saved Setup
5.4. Deleting a saved setup A configuration file is deleted from the Main/Setup/User/Files menu, by means of the file manager, which lists all of the configuration files (extension .CFG) found in directory « /media/sdcard/config/ ». When the file has been selected (Up/Down keys), a press on F1 activates the deletion. -

In this case, it is not powered and so consumes no energy. To use this function, you must first activate it from the Main/Parameters/Bluetooth menu by setting the Activation item to "On"... -
Page 26: Disconnecting A Headset
When the item has been selected in the Main/Parameters/Bluetooth menu, validation by F2 makes it possible to choose the "New..." value (Up/Down arrows) and another validation by F2 applies it. The pairing starts; after a few seconds, the connection is made. -

Page 28: Changing The Frequency Of Reading Of A Bluetooth Peripheral
6.3.7. Changing the frequency of reading of a Bluetooth peripheral From the peripherals manager (above), it is possible to change the reading period of the selected peripheral: the Right arrow is used to start the entry of a new reading period. The period is displayed on a blue ground with the symbol indicating that the Up/Down arrows can now be used to change its value. -
Page 29: Using A Bluetooth Measurement As An Influencing Parameter
6.3.9. Using a Bluetooth measurement as an influencing parameter The three influencing quantities taken into account in the correction of the thermograms are the ambient temperature, the distance from the target, and the ambient relative humidity. If you have a Bluetooth sensor compatible with the camera and capable of making one of these measurements, the value read can be used in the calculation of the correction for the influencing parameters. -
Page 30: Displaying The Bluetooth Measurements On The Main Screen
6.3.10. Displaying the Bluetooth measurements on the main screen As described above, it is possible to assign a use to measurements. If a measurement is "Displayed" or "Influence", it will appear in blue on the last line of the measurement zone of the screen (unless the profile cursor is activated, because of lack of space). -
