7.4 Bus status display
The measuring system has two Bus specific LEDs in the connection hood. A red LED
(Bus Fail) to display faults and a green LED (Bus Run) to display status information.
When the measuring system starts up, both LEDs flash briefly. The display then
depends on the operational state.
