Measurement and Instrumentation Why is a MISC meter not recommended for DC measurement? The error is high due to eddy current effect The error is high due to hysteresis 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 eddy current effect The error is high due to hysteresis 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
