>>>Long-term stability (according to DIN 16086 and IEC 60770-1)
Applies to the digital signal output (HART, Profibus PA, Foundation Fieldbus) as well as to the
analogue current output 4 … 20 mA under reference conditions. The specifications refer to the set
span. Turn down (TD) is the ratio nominal measuring range/set span.
The long-term drift of the zero signal corresponds to the value F
Stab
in chapter "Calculation of the
total deviation (according to DIN 16086)".
