An ammeter has a non-nr xgmv nfc(365egligible zero offsa9*h -agbzjzb9f 6 lr-et error. Which of the following statementl9z gr*-ja9-h zaf bb6s is 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/eqv 1 qdxi.g 8p)zr:z systematic error in the ammeter readings. A large systematic error results in measurements which arevdezr qg/i1zp qx. )8: 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.
