使用中或修理后的上仪九厂10～18毫米内径百分表,由于V型调值件(图1)倾斜角度因紧固螺丝的松动而改变(见图2),使得示值误差超出规程允许的数值,这时就需要进行调整。调整时,先将V型调值件正确地安装在主体上,稍微紧固小螺钉,根据“正值超差(表明传动角大于45°)朝右微动调值件,负值超
In use or repair of the instrument on the nine plant 10 ~ 18 mm diameter dial indicator, due to the V-shaped adjustment piece (Figure 1) tilt angle due to loose screws change (see Figure 2), making the indication error exceeds The value allowed by the rules, then need to be adjusted. Adjustment, the first V-shaped adjustment member installed correctly on the main body, a small fastening screws, according to the "positive over tolerance (indicating that the transmission angle greater than 45 °) fine tune the value of the tune to the negative, ultra-negative
