5.6 Bus status display
The measuring system has four LEDs in the connection hood. Two green LEDs for the
connection state and two yellow LEDs for the data transmission state.
When the measuring system starts up the LEDs are controlled like a running light
three times and indicate that the measuring system is in the initialization procedure.
The display then depends on the operational state.
