Scaling the measuring range
• With the parameter "Lower end of analog output" (
ASP
) you can
select the measuring value for which the output signal is 4 mA.
• With the parameter "Upper end of analog output" (
AEP
) you can
select the measuring value for which the output signal is 20 mA.
• Minimum distance between ASP and AEP = 25 % of the span (scal-
ing factor 4).
The output signal is between 4 and 20 mA in the set measuring range.
It is also indicated:
• System pressure above the measuring range: output signal > 20 mA.
• System pressure below the measuring range: output signal drops to
max. 3.2 mA (depending on the scaling).
