Page 14: Changing The Image Storage Location
1.5.7. Changing the image storage location To specify the working directory to which images are stored, select the icon from the Main/Files menu. The working directory must be located on the micro SD card, which must be present in the device. By default this is "1:/images."... -
Page 15: Basic Operation
2. BASIC OPERATION By default, no measurement cursor is selected (the icon in the Main/Display/Cursor menu is highlighted), 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 color palette. The distribution of the colors between the minimum and maximum temperatures displayed at the ends of the palette is linear, so simply interpolating based on the position of the color in the palette provides an estimate of the temperature. -
Page 16: Freezing The Colors Representing The Temperatures
2.7. Freezing the colors representing the temperatures By default, assignment of colors is automatic and is recalculated for each image as a function of the temperatures of the hot and cold spots in the image. As a result, a given color does not necessarily represent the same temperature from one image to another, if the hot and/or cold spots change. -
Page 17: Advanced Operation
3. ADVANCED OPERATION 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 as large as possible. Avoid point-like scenes. If the ambient temperature changes significantly, allow the camera to stabilize. ... -
Page 18: Using Custom Compensation Settings
3.2.2. Using custom compensation settings This calculation mode is necessary when the measurement conditions are significantly different from the calibration conditions (emissivity, relative humidity) and the application requires high accuracy. To use custom settings, select Influence in the Main/Target menu and change the setting to User. When user compensation is selected, these parameters can be adjusted: ... -
Page 19: Saving And Recalling Images
4. SAVING AND RECALLING IMAGES If the micro SD memory card is inserted into the camera, you can store and later recall the current image and measurements displayed. 4.1. Image file naming conventions The camera has two objectives, one for infrared images and the other for visible light images. When an image is saved, two files created. -
Page 20: Image File Directories
Depending on the situation, 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). -
Page 21: 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 installed in the camera. The Images menu lists only infrared images generated by the camera bearing a name in the form yyyymmdd_hhmmssX_IR.BMP, along with the folders, to allow browsing in the SD card directory tree. -
