一、特點
1、 Characteristics
1、具有預設扭矩數(shù)值和聲響裝置。當緊固件的擰緊扭矩達到預設數(shù)值時，能自動發(fā)出訊號“卡嗒”(click)的一聲，同時伴有明顯的手感振動，提示完成工作。解除作用力后，扳手各相關零件能自動復位。
1. With preset torque value and sound device. When the tightening torque of the fastener reaches the preset value, it can automatically send a signal "click", accompanied by obvious hand vibration to prompt the completion of the work. After releasing the force, all relevant parts of the wrench can be reset automatically.
2、可切換二種方向。撥轉棘輪轉向開關，扳手可逆時針加力。
2. Two directions can be switched. Turn the ratchet steering switch and apply force to the wrench counterclockwise.
3、公、英制(N.m、lbf.ft)雙刻度線;手柄微分刻度線。讀數(shù)清晰、準確。
3. Metric and imperial (N.m, LBF. Ft) double scale marks; Handle differential scale line. The reading is clear and accurate.
4、合金鋼材料鍛制，堅固耐用，壽命長。校準追溯美國技術標準學會(NBS)。
4. Forged with alloy steel, it is firm and durable with long service life. Calibration is traceable to the National Institute of technical standards (NBS).
5、精 確度符合ISO6789：1992.ASMEB107.14,GGG-W-686.±4%。
5. The accuracy conforms to iso6789:1992.asmeb107.14, ggg-w-686. ± 4%.
二、使用方法
2、 Method of use
1、根據(jù)工件所需扭矩值要求，確定預設扭矩值。
1. Determine the preset torque value according to the required torque value of the workpiece.
2、預設扭矩值時，將扳手手柄上的鎖定環(huán)下拉，同時轉動手柄，調(diào)節(jié)標尺主刻度線和微分刻度線數(shù)值所需扭矩值。調(diào)節(jié)好后，松開鎖定環(huán)，手柄自動鎖定。
2. When preset the torque value, pull down the locking ring on the wrench handle, turn the handle at the same time, and adjust the values of the main scale line and differential scale line of the scale to the required torque value. After adjustment, release the locking ring and the handle will lock automatically.
3、在扳手方榫上裝上相應規(guī)格套筒，并套住緊固件，再在手柄上緩慢用力。施加外力時必須按標明的箭頭方向。當擰緊到發(fā)出信號“卡嗒”(click)的一聲(已達到預設扭矩值)，停止加力。一次作業(yè)完畢。
3. Install sockets of corresponding specifications on the square tenon of the wrench, sleeve the fasteners, and then slowly apply force on the handle. The external force must be applied in the direction of the indicated arrow. When the torque is tightened to a "click" signal (the preset torque value has been reached), stop the force application. One operation is completed.
4、大規(guī)格扭矩扳手使用時，可外加接長套桿以便操作省力。
4. When a large-size torque wrench is used, an extension sleeve rod can be added for labor-saving operation.
5、如長期不用，調(diào)節(jié)標尺刻線退扭矩小數(shù)值處。
5. If it is not used for a long time, adjust the scale marking to the small value of torque.
