辨別扭力大小，需要你把鋰電扳手開機一下，然后你觀察手柄下功能鍵旁亮起的小燈，如果亮在大扭力位置，說明鋰電扳手處于大扭力。如果在小扭力處燈亮，那么說明處于小扭力。判斷電動扳手的扭力大小，需要在開機運轉的時候，看開關手柄下的功能鍵，上面有大扭力和小扭力提示。如果燈亮在大扭力，說明這電板手扭力處于大，如果在小扭力燈亮，說明處于小扭力。
To identify the torque, you need to turn on the lithium wrench, and then observe the small light that lights up next to the function key under the handle. If it lights up at the high torque position, it means that the lithium wrench is at the high torque. If the light is on at small torque, it means it is at small torque. To judge the torque of the electric wrench, you need to look at the function key under the switch handle when starting and running. There are big torque and small torque prompts on it. If the light is on at high torque, it means that the electric wrench is at high torque. If the light is on at low torque, it means that it is at low torque.

扭剪扳手廠家認為，扭力預設時的一些注意事項還需多多了解，比如：預設扭力值時，將板子手柄上的鎖定環(huán)下拉，同時轉動手柄，調節(jié)標尺主刻度線和微分刻度線數據所需扭力值。調節(jié)好后，松開鎖定環(huán)，手柄自動鎖定。在板子方榫上裝上相應規(guī)格套筒，并套住緊固件，再在手柄上緩慢用力。施加外力時須按標明的箭頭方向。當擰緊到發(fā)出信號"卡嗒"一聲（已達到預設扭力值），停止加力。
In addition, some precautions for torque presetting need to be understood. For example, when presetting the torque value, pull down the locking ring on the handle of the board, and turn the handle at the same time to adjust the data of the main scale and differential scale of the scale to the required torque value. After adjustment, release the locking ring and the handle will automatically lock. Install a sleeve of corresponding specification on the square tenon of the board, cover the fastener, and then slowly apply force on the handle. When applying external force, follow the indicated arrow direction. When the screw is tightened to a signal "click" (the preset torque value has been reached), stop the afterburner.
很大規(guī)格扭力扳手使用時，可外加接長套桿以便操作省力。如長期不用，調節(jié)標尺刻線退扭力小數據處。
When using a large torque wrench, an extension sleeve can be added to save labor. If it is not used for a long time, adjust the scale line back to the small torque data.
使用扭力扳手時，應均衡緩慢地加載，切不可猛拉猛壓，以免造成過載，導致輸出扭力失準。在達到預臵扭力后，應停止加載。所選用的扭力扳手的開口尺寸須與螺栓或螺母的尺寸一致，各類板子的選用原則，一般優(yōu)先選用套筒板子，其次為梅花板子，再次為開口板子，后選活動板子。
When the torque wrench is used, it should be loaded evenly and slowly, and should not be pulled and pressed violently, so as to avoid overloading and inaccurate output torque. Stop loading after reaching the preset torque. The opening size of the selected torque wrench must be consistent with the size of the bolt or nut. The selection principle of various types of plates is generally to choose sleeve plate first, then plum plate, then open plate, and then movable plate.
