Measurement tools with digital displays are more accurate than those with analog displays. Is this statement true or false?

• A. True
• B. Not sure
• C. False
• D. Sometimes

Answer: (C)

Accuracy comes from the instrument’s design, calibration, and the quality of its sensors, not from the readout format. Digital displays provide clear numeric readings and reduce interpretation errors like parallax, which can help readability. But the true accuracy is limited by the measurement hardware, the resolution and accuracy of the ADC or sensor, and any rounding or noise in the signal. Analog displays show a continuous value, which can be read with great precision, but reading a pointer can introduce human-reading errors. If an instrument is well-designed and properly calibrated, it can be equally accurate whether its readout is digital or analog. Therefore, the statement is not universally true.
