10.9 Measuring areas
10.9.1 General
The distance measured by the laser distance meter can be used as the basis for area cal-
culations. A typical application is to estimate the size of a damp stain on a wall.
To measure the area of a surface, you need to lay out a box or circle measurement tool on
the screen. The camera calculates the area of the surface enclosed by the box or circle
tool. The calculation is an estimate of the surface area, based on the measured distance
to the target.
When the laser distance meter is on, you will see a laser dot approximately at the target.
The laser distance meter measures the distance to that target. The camera assumes that
this distance is valid for the entire box or circle tool.
For successful area measurements, keep the following in mind:
• Make sure that the box or circle tool is in the center of the image.
• Adjust the size of the box or circle tool to the size of the target.
• Hold the camera perpendicular to the target.
• Avoid targets with many details at different distances from the camera.
10.9.2 Procedure
Note This procedure assumes that you have enabled the laser. Select ( Settings ) >
Device settings > Lamp & laser > Enable lamp & laser .
Follow this procedure:
1. Add a box or circle measurement tool, see section 15.2 Adding/removing measure-
ment tools , page 69.
2. Set the camera to measure and display the area of the box or circle, see section 15.6
Displaying values in the result table , page 74.
3. Make sure that the box or circle tool is in the center of the image, see section 15.4
Moving and resizing a measurement tool , page 70.
4. Adjust the size of the box or circle tool to the size of the target, see section 15.4 Moving
and resizing a measurement tool , page 70.
5. Hold the camera perpendicular to the target. Push and hold the laser button .
6. The calculated area is displayed in the result table.
10.10 Connecting external devices and storage
media
10.10.1 General
You can connect the following external devices and media to the camera:
• An SD memory card.
• A computer to move image and video files to and from the camera, using a USB-C to
USB-A cable.
• A video monitor or projector, using a USB-C to HDMI adapter.
• A USB battery charger.
Note Empty or use a memory card that has not previously been used in another type of
camera. The cameras may organize files differently on the memory card. There is there-
fore a risk of losing data if the same memory card is used in different types of cameras.
