(1) Total performance is determined by performing a root sum square calculation on reference accuracy, ambient temperature effect, and line pressure effect errors.
For F
OUNDATION fieldbus transmitters, use calibrated range in place of span. For zero based spans, reference conditions, silicone oil fill, SST materials, Coplanar flange
(2051C) or
1
/2 in. - 18 NPT (2051T) process connections, digital trim values set to equal range points.
