Applies also to the analogue 4 ... 20 mA current output and refers to the set span.
Thermal change, current output
The thermal change of the current output corresponds to the value F
total deviation (according to DIN 16086)".

Applies to the respective digital signal output (e.g. HART, Profibus PA) as well as to analogue cur-
rent output 4 ... 20 mA under reference conditions. Specifications refer to the set span. Turn down
(TD) is the ratio nominal measuring range/set span.
