Applies to the digital signal output (HART, Profibus PA, Foundation Fieldbus) as well as to ana-
logue current output 4 ... 20 mA and refers to the set span. Turn down (TD) is the ratio nominal
measuring range/set span.

Influence of the product or ambient temperature
Average temperature coefficient of the zero signal and the output span
Applies to the digital signal output (HART, Profibus PA, Foundation Fieldbus) as well as to ana-
logue current output 4 ... 20 mA and refers to the set span. Turn down (TD) is the ratio nominal
measuring range/set span.
Incl. non-linearity, hysteresis and non-repeatability.
