10 Supplement
VEGABAR 55 • 4 … 20 mA/HART
36734-EN-130321
Long-term stability (according to DIN 16086 and IEC 60770-1)
Applies to digital HART interface as well as to analogue current output 4 … 20 mA under refer-
ence conditions. Specifications refer to the set span. Turn down (TD) is the relation nominal meas-
uring range/set span.
Long-term drift of the zero signal:
Ʋ For one year < 0.05 % x TD
Ʋ For five years < 0.1 % x TD
Ʋ For ten years < 0.2 % x TD
