Measurement and Instrumentation Why is a MISC meter not recommended for DC measurement? 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 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 ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation A resistance is measured by the voltmeter-ammeter method employing dc excitation and a voltmeter of very high resistance connected directly across the unknown resistance. If the voltmeter and ammeter reading are subject to maximum possible errors of ± 2.4 % and ± 1.0 % respectively, then the magnitude of the maximum possible percentage error in the value of resistance deduced from the measurement is nearly ± 1.4% ± 2.4% ± 3.4% ± 1% ± 1.4% ± 2.4% ± 3.4% ± 1% ANSWER DOWNLOAD EXAMIANS APP
