A Smart DP transmitter with built-in square root characterization is used to measure flow through a pipe. The orifice plate range is 0 to 125 inches WC at 0 to 277 gallons per minute: A technician removes the transmitter from service and tests it by applying several air pressures to the “H” port while leaving the “L” port vented. Here are the As-Found results: Calculate the largest error, in percent of (output signal) span. Also, determine whether this looks like a zero or span error, and whether that error exists in the input (ADC) of the smart transmitter or in
