An ammeter has a non-negligw7 : cat5iq4 ttzf:x(abnc6 a/+xwt ,uible zero offset er0ado,p- qx jrayji 15,ror. Which of the following statements is corre,5jp,0 qaj -droiyx1a ct?
A. The readings from the ammeter will be accurate but not precise.
B. The readings from the ammeter will be neither accurate nor precise.
C. The readings from the ammeter will be precise and accurate.
D. The readings from the ammeter will be precise but not accurate.
参考答案: D
本题详细解析:
The zero offset error will produce a systematic error in the ammete n7u; 2:zwnmua4l /odyr readings. A large systematic error results in measurements which are not accurate, in other words far from the correct value. Precision refers tydlu;u7waz o /4:2 mnno how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
