Reading of wrench: if it is a torque instrument with a meter, directly read the data indicated by the pointer as the measured data value; If it is a sleeve plus auxiliary scale indicator, first read the scale value on the main scale, and then add the sum of the scale values on the auxiliary scale or differential cylinder

量数据值。

Quantity data value.

力矩大小=力矩主刻度指示线读数大小+微分刻度读数大小

Torque value = torque main scale indication line reading + differential scale reading

力矩大小=180+7=187（N.M）

Torque size = 180 + 7 = 187 (N.m)

调节好后，必须按回手柄下端锁定环，锁定力矩值。

After adjustment, the locking ring at the lower end of the handle must be pressed back to the locking torque value.

可以控制扭矩扳手的扭转方向；右图上扳手杆的刻度和把手上的一圈数字代表这个扳手的扭矩范围，单位是牛·米（Nm）。可以看见这个扳手高扭矩值到210，依次往下是200，190等等，每个刻度间距是10牛米；中间的这10个牛米，就要用把手上那一圈来控制了，可以看见上面刻有0，8，6，4等等数字。

The torsion direction of the torque wrench can be controlled; The scale of the wrench rod on the right figure and a circle of numbers on the handle represent the torque range of the wrench, and the unit is n · m (nm). It can be seen that the wrench has a high torque value of 210, followed by 200190 and so on. The spacing of each scale is 10 nm; The 10 nm in the middle should be controlled by the circle on the handle. You can see that the numbers 0, 8, 6, 4 and so on are engraved on it.

使用的时候，比如现在需要扭矩187牛米，先将把手边缘拧到和刻度180齐平的位置，然后将把手上那一圈数字里“7”的刻度（就是8和6之间的位置）对准扳手杆上的刻度中线（红色箭头指的那条线），就可以得到了。

When using, for example, 187nm torque is required. First screw the edge of the handle to the position flush with the scale 180, and then align the scale of "7" in the circle of numbers on the handle (that is, the position between 8 and 6) with the scale center line on the wrench rod (the line indicated by the red arrow).
