the two LEDs and is used for visualization of device status and error codes. The location of a dot (

determines which display is currently active.

If the right-hand dot is lit up, the measurement status is being indicated (status LED).
The display is automatically switched on for 10 seconds after the device is restarted or for 2 seconds
if the status changes. If the display is inactive, pressing the button (

measurement status (for 10 seconds). Pressing the button again switches between the display for
measurement and transmission (and lights the display for another 10 seconds).
