Use pause mode to temporarily stop scanning without ending the dataset.
Tap the Pause 
from the side bar to pause the scan. To resume scanning, tap Start 
.
When you tap pause, the PAUSED text in the top bar blinks until you resume the scan. A Paused notification also appears on some screens for a few seconds.
In pause mode, the device doesn't take images (auto-triggering is disabled) and doesn't add points to the point cloud. Pause mode is useful in the following scenarios:
You need to take a break while scanning.
People are visible to the device and shouldn't appear in the point cloud or panorama images.
You're working in an area where you don't want to capture panorama images or a point cloud, but want to continue capturing in the same dataset.
Note
In pause mode, only the scan process is paused, localization keeps running. To avoid reducing the quality of the recorded map, don't move faster or less carefully than normal.
