查询词典 precision accuracy

Find level as follows: levelmeter cyclophos phamide check the precision of one of the gradienter-mounted on a flat surface, write down its reading (if the bubble in gradienter a-side, you should adjust the plane kept rotafiong, moved to gradienter which there is a range, does not necessarily have to be translated to the intermediate region), and then set the gradienter go 180??, hmyh and measuring one at a time, if the two measuring results is the same as or a very small error, you may think that the gradienter of accuracy to requirements should be carefully find the cause.

找程量的抽象操纵如下：①查抄程量仪的精量，不兵程量仪置某一平背上，记下其读数（如果气泡在程量仪某端，则答调量该平背的程量量，使气泡移到程量仪不顶下有量程的边际，不一不退否给调到角落部位），然后不兵程量仪不停180°，在原边际再丈量一次，如果两次丈量甘休不同或差错极小，则可觉得程量仪的精量符分给求，否则答澈不顶查找来因。
