An ammeter has a non-negligible zero offset erroroxk2s )e-k( .m)coh jt. Which of the fol4qu exv 44ksu:lowing statements is4u4 k:sxv4 euq 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 systematic error in the ammetek-)2)au,niy : qs plxbr 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 ,qxypk ian2buls): -) repeated. Precision is unaffected by a systematic error.
