After making sure the battery is charged using the external wall charger, hold the power button for ~3 seconds to power up. Open the lens caps and press the center button (#3 in Fig. 1) to bring up the Main menu toolbar. Here you will choose the settings to identity cold spots in the core.

b) 1 - digital lens, 2 - Infrared lens, 3 - Switch to open/close lens cap, 4 - Trigger to take photo, 5 - Battery,
c) 1 - Main menu toolbar, 2 - Submenu toolbar, 3 - Spot Meter, 4 - Temperature reading, 5 - Battery/Memory meter, 6 - Temperature scale.
Main Menu Tabs
The far left tab is “Settings,” and contains three sub menus:
Measurement parameters
...
Emissivity should be set to “Semi-glossy (0.60),” Reflected temperature to 20C20 C, and Distance to 1 meter.
Save options
...
Photo as separate JPEG to “On”.
Device settings
...
Can stay at default.
Second from the left is “Image Mode,” and should stay at the default of “Thermal MSX,” which represents an infrared image with outlines of objects within the frame. This helps to keep the core in the center of the frame while scanning.
The middle tab is “Measurement,” and should be set to “Cold Spot.” ” This identifies the coldest spot within the frame, and displays the temperature reading in the upper left corner of the screen.
Second from the right is “Color,” and should be set to “Rainbow.” This tab has no effect on temperature reading or other measurements, but the “Rainbow” color scheme is the most familiar representation of infrared images (blue for cold, red for hot).
The far right tab is “Temperature Scale,” and should be set to “Manual.” Once set to “Manual,” use left or right on the Navigation Pad to select the upper limit of the scale, the lower limit of the scale, or both. Use up and down on the Navigation Pad to increase or decrease the limits of the temperature scale. The scale’s values and range are determined by the average temperature reading of the core as a whole. After finding the average temperature, chose limits approximately 5C above and below the core temperature for a range of 10c.
*IMPORTANT*
When camera is fully shut down (i.e. when switching batteries), “Image Mode” and “Temperature Scale” settings are reset to their default conditions:
...
In order to download the images, connect the USB cable to the port on the top of the camera and to the computer. The camera will mount to the computer like a hard drive, and from there the images can be transferred off the camera and the files can be renamed with the proper identification. To name the image, make sure to include the site number, hole, core section, type of image, and offset of the anomaly in centimeters from the top of the section. For example; U1445A_20F-2_Infrared_23-30.jpg.
Examples of usage
a) Core temperature (gas hydrate detection):
*Note: there is no ruler in this photo because it was a test True Color image. There is a ruler in the Infrared Image above.
b) Half-space puck during the data acquisition process in an effort to visually record the heating steps and in the hope of imaging the thermal gradient across the puck:
