    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 15: 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 16: Compensate The Difference Between The Internal Body Temperature And The Skin Temperature

    1.5.9. Compensate the difference between the internal body temperature and the skin temperature As default (offset = 0°C), the temperature measured on an individual is the skin temperature, which is approximately 2°C lower than the internal temperature. So the temperature measured on a healthy person will be close to 35°C rather than the 37°C that would be indicated by a medical thermometer (which generally makes this correction).

  • Page 17: Measurement Campaign

    2. MEASUREMENT CAMPAIGN By default, it is the MinMax cursor that is selected 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 19: Locating The Cold And Hot Spots In The Image

    Note that the temperatures accepted for this average must lie in the interval [30°C, 45°C]; if not, the measurement will be ignored. Note: as default, the camera measures the skin temperature of the person aimed at; this external temperature is approximately 2°C lower than the body's internal temperature.

When the palette is frozen, a red padlock appears on the palette; the min and max values are also red. When the mode is entered, the minimum changes to edit mode for a few seconds (on a blue ground with the symbol so that its value can be changed (Up/Down keys).

    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 22: Using A Tripod

    3.3. Using a tripod To improve the sharpness of the images and therefore the accuracy of the measurements, it is possible to use a support that prevents extraneous movements. The camera can be attached to the tripods used in photography using the ¼-inch-diameter insert on the underside of the handle, on the battery compartment cover.

  • Page 23: 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 an image is recorded, two files are created, one for the infrared image, named "yyyymmdd_hhmmss_IR.PNG", the other for the visible image, having the same name but without the IR extension ("yyyymmdd_hhmmss.PNG"), where yyyymmdd_hhmmss is the date and time of acquisition of the image (the operator must take care to reset the system date and time in advance, see §1.5.2.

  • Page 24: 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 25: 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.

    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. Connecting a headset). To play back the vocal message associated with an image, the image must be recalled (see §4.6.

  • Page 27: 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 28: 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 29: 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.
