Scaling of the measuring range
• With the parameter analog starting point
ASP
, you determine at which
measured value the output signal is 4 mA.
• With the parameter analog end point
AEP,
you determine at which
measured value the output signal is 20 mA.
• Minimum distance between
ASP
and
AEP
= 25 % of the measuring range
end value
Measuring range scaled
Factory setting
MEW = measuring range end value
In the adjusted measuring range, the output signal is between 4…20 mA.
Furthermore, the following signals are issued:
• Flow rate above the measuring range:
Output signal > 20 mA
• Flow rate below the measuring range:
Output signal between 3.6 and 4 mA.
