6. Operator interface
The evaluation unit is a multi-sensor evaluation unit. So it is strongly recommended to check before commissioning
whether the correct sensor is selected under menu item
System
.
The operator interface differs depending on the system design:
•
DIN Rail housing without touchscreen, operation via PC software
•
Field housing with display, alternative operation via PC software
•
One to three sensor system
In the following, the basic operation of the PicoFlow system will be described as a one sensor system without
re-entering the differences between the various variants.
6.1 Differences between the DIN Rail and field housing Evaluation unit
The MSE 300 in the DIN Rail housing is only a part of the functions available in the field housing.
The following overview clarifies the differences between the two versions.

The evaluation unit in the DIN Rail can only be configured via an USB connection and a PC program. On the
evaluation unit in the field housing, all functions can be configured by menu via the touch-sensitive display.
The field housing evaluation unit can also be configured by PC.
The menu items on the display and in the PC software are numbered uniformly so that they can be
referred to later on.
