[单选题]
An ammeter has a non9ntse +.yu,c j-negligible zero offset error. Which of the following statemjecsu+.9 nyt,2ggt a 0.rh pqvro2x,o2wx70kents 2x xrpowo 2vrak7h ,tq0 2g.g0is 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 wiu++zbdw4gs d 91wrvr2ll produce a systematic error in the ammeter readings. A large systematic error results in measuremzdr+b4u r1w9v2s w+d gents 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 by a systematic error.
