[单选题]
An ammeter has a nonpgbx*;(2gls 0 ,hfbah-negl *v9vplqc *nzb7jw qw,7v1p9oigible zero offset error. Which of the following statements p*ovnv17 l9z7pw ,wq9q v*b jcis 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 systemkf(ulo,1 ( rxsatic error in the ammeter readings. A large systematic error results in measurements which are not accurate, in othe ((fx rlosu,1kr 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.
