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.
Deviation
Ʋ Turn down 1 : 1 up to 5 : 1 < 0.1 %
Ʋ Turn down > 5 : 1 < 0.02 % x TD
Influence of the product or ambient temperature
Thermal change zero signal and output span
11) Incl. non-linearity, hysteresis and non-repeatability.
