试验机安装的水平与否对其示值精度将产生影响。一般来说测力部分若不水平对示值产生负偏差,主体部分不水平则对示值产生正偏差。本文就怎样保证试验机水平度这个问题谈一点体会。液压式万能试验机的安装,一般都是按照说明书的要求用精度为0.2/1000的水平仪进行校正的。采取这种方法,一是基准点难以掌握;二是基准面有可能 The level of the test machine installation will have an impact on its indication accuracy. In general, if the force measurement part of the level of the negative bias, the main part of the level is not positive on the indication of bias. This article on how to ensure the level of testing machine talk about this issue a little experience. Hydraulic universal testing machine installation, are generally in accordance with the requirements of the manual with a precision of 0.2 / 1000 level calibration. To take this approach, one is difficult to grasp the benchmark; the second is the datum possible
