An ammeter has a non-negligible zevdr*r5 + cpoem,00.fqjog5x+bpc 7woro offset error. Which of the followin6*e21p /x trf* edyy249alyzfo4gfqe g statements is correct 1lz4t4ffegfye re2d*y *qap/92o xy6 ?
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 ammeter k ks+hrz6*z,a 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 the experiment is repeated. Precision is unaffected rk 6ashz,z+k*by a systematic error.
