  • Page 13: Screen Brightness

    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.

  • Page 14: Color Palettes

    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.

  • Page 15: Basic Operation

    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 §...

  • Page 16: Point

    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.

  • Page 17: Advanced Operation

    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. ...

  • Page 18: Custom Compensation Settings

    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 .

  • Page 19: Saving And Recalling Images

    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.

  • Page 20: Voice Recording

    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: ...

  • Page 21: Playing Back A Voice Recording

    4.3.3. Playing Back a Voice Recording A voice recording is played back using the Bluetooth headset, which must be connected to the camera (see § 6.2.1). To play back the recording associated with an image, the image must be recalled (see §...

  • Page 22: Derived Files From Recalled Images

    Pressing when viewing a recalled image displays the Recall menu (left). This presents six options:  Cursor displays the Cursor menu for selecting the cursor function (§ 2.1).  Palette displays a menu of available color palettes (§ 1.5.8).  Show toggles between the IR image and visible light image.

  • Page 28: Replacing Peripherals

    F1, F2, and F3 in this screen function as follows: Search for Bluetooth peripherals. Peripherals already connected remain on the list. Those having the highest signal levels are added and connected until the three connected peripherals maximum is reached. Reconnect all peripherals in the list. Close the Peripheral screen.

  • Page 29: Using A Measurement To Compensate For Environmental Factors

    If no measurement is listed, ensure the measurement setting on the peripheral is set to a measurement type supported by the camera (see the table below). If the measurement still does not appear, change the setting on the peripheral and then change it back to the desired setting to reset the measurement type.
  • Page 30 You can use a measurement from a connected peripheral as an “influence” to compensate for an environmental factor. The measurement will be used to calculate the amount of correction that needs to be applied. Note that this option is available only for temperature, humidity, and distance measurements. For the measurement to be used as a compensation factor: 1.
