Measurement and Instrumentation Why is a MISC meter not recommended for DC measurement? The error is high due to hysteresis effect The error is high due to eddy current effect The meter does not respond to DC signals The meter is calibrated for AC and it’s error for DC would be high The error is high due to hysteresis effect The error is high due to eddy current effect The meter does not respond to DC signals The meter is calibrated for AC and it’s error for DC would be high ANSWER DOWNLOAD EXAMIANS APP

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
