I have a field transmitter say a FT (with accuracy in %RD) whose signal goes to a signal isolator (with accuracy in % FS) and an indicator ( with accuracy in %FS) in panel. Generally to know the overall accuracy, we take square root of sum of squares of individual accuracies. Is this method applicable when one instrument in the loop is having accuracy in %RD ? If not how to calculate the overall accuracy?. More over in some instruments, accuracies are expressed in engineering units (like Radar level transmitter). When a loop contains such instrument, how to calculate overall accuracy?
