The camera starts.
The start screen appears on the
display.
To ensure measuring accuracy, the camera performs automatic zeroing
approx. every 60 s. A “click” is heard when this happens. The image
freezes briefly when this occurs. Zeroing is carried out more frequently
during the camera warm-up period (takes approx. 90 seconds).
During the warm-up period no measuring accuracy is guaranteed. The
image can already be used for indication purposes and saved.
