Measurement and Instrumentation Why is a MISC meter not recommended for DC measurement? The meter does not respond to DC signals The error is high due to hysteresis effect The meter is calibrated for AC and it’s error for DC would be high The error is high due to eddy current effect The meter does not respond to DC signals The error is high due to hysteresis effect The meter is calibrated for AC and it’s error for DC would be high The error is high due to eddy current effect ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation In DC potentiometer measurments, a second reading is often taken after reversing the polarities of the DC supply and the unknown voltage and the average of the two reading is taken. This is with a view of eliminate the effects of Errorneous standardisation. Stray thermal emfs. Ripples of the DC supply. Stray magnetic fields. Errorneous standardisation. Stray thermal emfs. Ripples of the DC supply. Stray magnetic fields. ANSWER DOWNLOAD EXAMIANS APP
