Scaling The Measuring Range - TESTO 6446 Instruction Manual

Scaling the measuring range

8.2.9
- With the analog starting point parameter ASP, you determine at which
measuring value the output signal is 4 mA.
- With the analog end point parameter AEP, you determine at which
measuring value the output signal is 20 mA.
- Minimum distance between ASP and AEP = 25% of final value of
measuring range
MEW = final value of measuring range
The output signal is between 4 and 20 mA in the set measuring range.
Further signals are:
• Flow rate above the measuring range: output signal > 20 mA
• Flow rate below the measuring range: output signal between 3.6 and
4 mA.
