T
he simulation of the measured value is used to check the outputs and
connected components
. I
t can be applied to the percentage value

lease note that connected system parts
(
valves

)
are in
fl
uenced by the simulation
,
thus unintentional
plant operating conditions can occur
. T
he simulation is terminated
automatically after approxminately
10
minutes
