参考答案:  D


本题详细解析:
The zero offset error w)n r.cv;h)wx gill produce a systematic error in the ammeter readings. A large systematic erwrg))hvn.c ;xror results in measurements which are not accurate, in 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.
