扳手的讀數(shù)：如果是帶表扭力儀器，直接讀取指針?biāo)甘镜臄?shù)據(jù)為測量數(shù)據(jù)值；如果是套筒加副刻度指示器，應(yīng)先讀取主刻度上的刻度值，再加上副刻度或微分筒上的刻度值之和為測
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
量數(shù)據(jù)值。
Quantity data value.
力矩大小=力矩主刻度指示線讀數(shù)大小+微分刻度讀數(shù)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)
調(diào)節(jié)好后，必須按回手柄下端鎖定環(huán)，鎖定力矩值。
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轉(zhuǎn)方向；右圖上扳手桿的刻度和把手上的一圈數(shù)字代表這個扳手的扭矩范圍，單位是牛·米（Nm）。可以看見這個扳手高扭矩值到210，依次往下是200，190等等，每個刻度間距是10牛米；中間的這10個牛米，就要用把手上那一圈來控制了，可以看見上面刻有0，8，6，4等等數(shù)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.
使用的時候，比如現(xiàn)在需要扭矩187牛米，先將把手邊緣擰到和刻度180齊平的位置，然后將把手上那一圈數(shù)字里“7”的刻度（就是8和6之間的位置）對準(zhǔn)扳手桿上的刻度中線（紅色箭頭指的那條線），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).
