An ammeter has a non:vt1zf. uc:0 3 kst d2jtfe5hqnw 8 ;e*rrlode+ (up l(7u3 ttcg);mww-negligible zero offset error. Which of the following statem ;l( pur3;7w)wgoel nd8*etruc w(t+ments 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 p9q a hgoq6r0e8roduce 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 the experimeaqheq8 rg960ont is repeated. Precision is unaffected by a systematic error.
