12. Radioactivity level. The radioactivity level is shown with
large figures in the center of the screen. When the device is taking measure-
ments for the first time, the word «Measurement» appears on the screen.
13. Units: μSv/h
14. Measurement results ready indicator: fills in less than 10
seconds. If the background radiation level is high, it may take considerably
less time.
15. Accuracy indicator: fills in with green the better the accuracy
is. With each subsequent measurement (10 seconds) the bar in the indicator
field grows until it fills all the area, which takes less than 2 minutes (12
measurements). If during the process sharp changes in the background are
detected (more than a 3-fold increase, or more than a 10-fold decrease), the
accuracy indicator is set to zero. This allows detecting sharp changes in the
background levels and displaying reliable values in less than 10–20 seconds.
