一、试验机示位超差为-1％①机体垂直度超过安装要求; ②夹具或反向器歪扭不同心; ③刀刃松动或损坏; ④推杆、压杆、摆杆、机架变形。二、示值误差超过±1％但度盘各点示值误差基本相同①杠杆臂比改变,如摆锤短臂刀刃松动,受力时产生位移,应调整固紧;

First, the test machine bit tolerance of -1% ① body perpendicularity exceeds the installation requirements; ② fixture or inverter crooked different hearts; ③ blade edge is loose or damaged; ④ putt, pressure bar, swing bar, rack deformation . Second, the indication error of more than ± 1% but the disk shows the same point of view the same error ① lever arm than the change, such as pendulum short-arm knife loose, forced displacement, should be adjusted tight;
