6.2 Basics of the Operating Concept
The display module consists of a dot-matrix

The four buttons below the display allow an
intuitive operation of the device. The gen-

all operating modes.

Icon indicating device status
Data area
Bar graph related to the currently measured value

The icon for the device status (see 6.3.3) as well as the bar graph is displayed in each op-
erating mode. The bar graph always shows the state of the current output (4 mA = 0%, 20
mA = 100%). The contents of the header and the data area depend on the operating
mode:
