Measurement and Instrumentation Assertion (A) : It is always desirable to take the reading of an indicating instrument very close to the full scale reading. Reason (R) : Accuracy of an indicating instrument is maximum at the full scale deflection and error increases as reading comes closer to the beginning of the scale. Both A and R are true and R is the correct explanation of A A is true but R is false Both A and R are true but R is NOT the correct explanation of A A is false bur R is true Both A and R are true and R is the correct explanation of A A is true but R is false Both A and R are true but R is NOT the correct explanation of A A is false bur R is true ANSWER DOWNLOAD EXAMIANS APP
