Dear Emerson Support
I need to confirm the calculation of Reference accuracy of 3051SCD2 Ultra Differential Pressure Transmitter. The datasheet says:
±0.025% of span;
For spans less than 10:1, ±(0.005 + 0.0035[URL/Span])% of span
So the question is what does it mean that Span is less than 10:1. Does it mean that when URL/Span <10 then we should use ±(0.005 + 0.0035[URL/Span])% of span
and when URL/Span >10 we should use ±0.025% of span
Because what I understand that as we use a larger turn down ratio, the accuracy of the equipment goes down (gets worse). Can you please confirm this understanding?
