Layout
The layout of the gauge depends on the configuration. Up to three differently colored areas
can be set on the scale to visualize different operating states, such as normal operation,
warning range and danger range.
A trailing pointer can display the maximum value reached on the scale. The trailing pointer is
reset when the screen is reloaded.
The label on the scale can show the measured variable, e.g. boiler pressure, and the
physical unit, e.g. bar.
Operation
The gauge is for display only and cannot be controlled by the operator.
