Effect of ambient
temperature
Ambient temperature effect on zero and span in relation to the set measuring span. Applies to
the digital interfaces (HART
® , Profibus PA, Foundation Fieldbus) as well as for the analogue
4…20 mA current output.

Effect of system
pressure
Ambient temperature effect on zero point and span in relation to the set measuring span. Zero
point errors can be calibrated out under operating pressure. Applies to the digital interfaces
(HART
® , Profibus PA, Foundation Fieldbus) as well as for the analogue 4…20 mA current
output.
