A) measurement field B) scope (span) c) linearity
2.- How do you know the algebraic difference between the upper and lower values of the instrument's measuring range?
A) measurement field B) scope (span) c) linearity
3.- How do you know the deviation from the practical measures of a process variable in relation to the theoretical or ideal measures?
a) Measurement error B) human error C) Absolute error
4.- What is the absolute error?
A) close value B) Related value c) value read/True Value
5.- What does the relative value represent?
A) relative error B) Absolute error/True error C) True Value
6.- What is the quality of an instrument that tends to give very approximate readings to each other?
a) Precision b) Accuracy c) Precision and Accuracy
7.- How do you know the value field of the variable that does not vary the indication or the output signal of the instrument?
