4.11.1.
On top of the housing, the instrument is equipped with two (or three) LED indicators and a multifunctional switch, which
can be used to monitor the instrument visually and start several functions manually.
The LEDs on top of the instrument indicate the operational state. The meaning of some indications depends on the
specific fieldbus interface of the instrument (if installed).
