七一年公布的百分表试行检定规程比过去的规程多了一项百分表灵敏度的要求。我厂计量室检定人员根据多年实践经验,在原百分表检具上加了一个附件用于灵敏度的检定,使用起来比较方便,既保证了检定精度,而且制造也很简单。现在我们把它介绍出来,供兄弟单位参考。作一件带顶尖的方架(见图中的 A)并把它安装到百分表检具夹持被检百分表的支座上,注意保证顶尖中心线与百分表测杆中心处于同一平面上。再按规程要求,做一件长度适宜的标杆(图中的 B)就可以使用了。
The test of the percent test released in July exceeds the requirements of a percentage of the sensitivity of the meter in the past. I plant measurement room accreditation officers based on years of practical experience, the original instrument on the dial indicator added an attachment for the sensitivity test, more convenient to use, both to ensure the accuracy of test, but also very simple to manufacture. Now let’s introduce it for reference by brothers. Make a top square frame (see A in the figure) and attach it to the dial gauge holder holding the dial indicator, taking care to ensure that the center line of the center of the dial gauge is at the center of the dial gauge On the same plane. According to the rules and requirements, make a suitable length of the benchmark (Figure B) can be used.
