An electronic balance has a button with “tare” written on it. The reading of the balance is reset to zero when the “tare” button is pressed. Which of the following gives a reason why use of the “tare” button improves the measurement?
A. Reduce systematic error
B. Reduce random error
C. Increase precision
D. Reduce percentage uncertainty of the measurement
参考答案: A
本题详细解析:
The “Tare” button resets the balance display to zero. It avoids zero error when measuring weight with a container. It does not change the precision of the balance or the absolute uncertainty of the measurement. Without the use of the Tare button, all values will be wrong by the same amount, which is a systematic error.
