Additional factor through Turn Down
The additional factor FTD through Turn down is calculated according to the following formula:
F
TD
= 0.5 x TD + 0.5
In the table, example values for typical Turn downs are listed.

Long-term stability (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.
