Deviation (according to IEC 60770-1)
Applies to the digital signal output (HART, Profibus PA, Foundation Fieldbus) as well as to the ana-
logue current output 4 ... 20 mA and refers to the set span. Turn down (TD) is the ratio "nominal
measuring range/set span".
The specified values correspond to the value F
Accuracy class

Influence of the product temperature
Thermal change zero signal and output span
Turn down (TD) is the relation nominal measuring range/adjusted span.
