4 FUNCTIONAL CHARACTERISTICS
4.1 CONFIGURABILITY
The DMC3S multifunctional panel features a modular construction with removable boards.
The panel can be customised for a variety of types of riser; the type of riser can be selected in the
Set \ Base menu.
The firmware selected on the panel defines the measured values of amperometric channel C2, while
the measurements on voltmetric channel V4 must be selected from UE and V2 in the Set \ Base menu.
