参考答案:  D


本题详细解析:
The zero offset error wi.g,x7wywz4px ll produce a systematic error in the ammeter readings. A large systematic error results in measurements which are not accurate, in other words far from the correct value. Precision refers to how reproducible the measurements are when t7wzx4 gpxw.,y he experiment is repeated. Precision is unaffected by a systematic error.
