An ammeter has a non-n 4tn pr1 ./ i7ujsa)mb5bimzk(egli*jcepzl1 x:m + nkp/k-quk0a tdh83y4gible zero offset error. Which of the following statements is ckzpdxm18 a 3*-:j0/ +u lp4tcnehyqkkorrect?
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 revzs72al:ca78p o ,wwvqr ct(,adings. A large systematic error results in measurements which are not accurate, in other words far from the correct value. P opc v 8a,lz7(va:q,s2rcwt7wrecision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
