Analogue evaluation
4.1 Analogue output
The measuring range can be scaled via the parameters [ASP] and [AEP]:
•
[ASP] determines at which measured value the output signal is 4 mA
•
[AEP] determines at which measured value the output signal is 20 mA
[ASP] must have a lower value than [AEP].

Observe the minimum distance between [ASP] and [AEP]

If the measured value is outside the measuring range or in the event of an internal error, the current
signal indicated in the following figure is provided.
