DO_(30) 型三用表校验仪是一种已生产了一、二十年的老产品,随着三用表型号的不断更新,这种检定设备已经越来越满足不了三用表的校验要求,成了不能完全用于校验三用表的三用表校验仪。作者在本文中所列举的情况是属实的。其实类似的问题在其它计量项目上也存在着。这种状况无疑对进一步发展和提高我国的计量技术水平是非常不利的。我们希望广大计量工作者也能象本文作者那样,对类似的问题提出讨论,为推动检定设备的更新换代作出贡献。
DO_ (30) type three-meter calibrator is a kind of old product that has been produced for one or two decades. With the continuous updating of the three-purpose meter model, the verification equipment has been more and more unable to meet the three-purpose meter Calibration requirements, has become can not be completely used to verify the three-use table with a three-meter calibrator. The author listed in this article is true. In fact, similar problems exist in other measurement items. This situation is undoubtedly unfavorable to the further development and enhancement of our country’s measurement technology. We hope that the majority of metrologists will also be able to discuss similar issues like the authors of this article and contribute to the upgrading of accreditation equipment.
