[单选题]
An ammeter has a nonefte2g6zed v gn0i2 ,8-negligiwqp* 6fn,xga* ble zero offset error. Which of the following statements gxf*p6,nqaw * is correct?

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 system2x x )3yd5cgvfatic error in the ammeter readings. A large systematic error results in measurements which are not accurate, in) g2dvxyxc35f other words far from the correct value. Precision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
