Specifications refer to the set span. Turn down (TD) is the ratio: nominal measuring range/set span.
Accuracy class Non-linearity, hysteresis and re-
peatability with TD 1 : 1 up to 5 : 1
Non-linearity, hysteresis and re-
peatability with 5 : 1
0.075 % < 0.075 % < 0.015 % x TD
0.1 % < 0.1 % < 0.02 % x TD
0.2 % < 0.2 % < 0.04 % x TD
Influence of the product or ambient temperature
Thermal change zero signal and output span
Turn down (TD) is the relation nominal measuring range/adjusted span.
