To measure areas, you need to add a temperature measurement rectangle or
circle on the screen. The thermal imager will calculate the area of the rectangle
or circle, according to the distance of the target. When the laser distance meter
is turned on, a laser dot can be seen on the measured target. The thermal
imager assumes that this distance is valid to the measurement area of the entire
rectangle or circle.
Please follow setting procedures as below:
1. Make sure the “save laser distance” is selected, in “save and storage options”.
2. Add a rectangle or circle measurement tool.
3. Make sure the box or circle tool is close to the center of the image.
4. Adjust the size of the box or circle tool to the size of the target.
5. Keep the thermal imager perpendicular to the target, and stable. Press the
capture button.
6. The calculated area will be displayed in the result table.
Note: Avoid multiple complex targets with different distances from the thermal
imager in the aiming area, otherwise it might cause measurement errors.
