Electric torque wrench is mainly used to install fasteners, such as bolts, screws and nuts. Through torque control, the tightening of thread is ensured and the thread will not be damaged due to excessive torque. Therefore, it is necessary to use the electric torque wrench to fix the torque value, and the fixed torque value needs to be preset during the application process. When the set value is reached, the electric torque wrench will send out a warning message. You can feel the hand vibration or hear the "click" sound, that is, the torque has been completed. When the torque value reaches the fixed position, no further force is required. Do not use impact force. After the force is stopped, all parts will be reset. When applying torque, hold your hand on the electric

動扭剪扳手手柄的中間刻度線上，并僅在電動扭剪扳手指示的方向上施加力，同時施力方向應(yīng)在±15°以內(nèi)（垂直方向和水平方向）。

On the middle scale line of the handle of the electric torque wrench, apply the force only in the direction indicated by the electric torque wrench, and the force application direction shall be within ± 15 ° (vertical and horizontal).

根據(jù)緊固件的強度和扭矩用以使用合適量程的扳手，并且不允許超過扳手的適用范圍。扳手在使用前需要調(diào)零，無荷載時注意對扭矩扳手指針的檢查，看指針是否在零標(biāo)度值上，如果不是則需要對其進行調(diào)整。

Use a wrench with appropriate range according to the strength and torque of the fastener, and do not exceed the applicable range of the wrench. The wrench needs to be zeroed before use. When there is no load, pay attention to check the torque wrench pointer to see if it is on the zero scale value. If it is not, it needs to be adjusted.

為確保讀數(shù)準(zhǔn)確，在使用過程中需要用一只手握住扳手的手柄，使扭矩扳手和拉力保持直角，并穩(wěn)定地施加力。 當(dāng)指針指向扭矩值時，禁止用力過大，否則會出現(xiàn)誤差值。 測量完成后，旋轉(zhuǎn)旋鈕將指針返回到零位，以便進行下一個應(yīng)用。 作為測量工具，必須注意保護電動扭剪扳手。禁止進行扔擲、震動以及敲擊

In order to ensure accurate reading, it is necessary to hold the handle of the wrench with one hand during use, keep the torque wrench and the tension at right angles, and apply the force stably. When the pointer points to the torque value, do not use too much force, otherwise the error value will occur. After the measurement is completed, turn the knob to return the pointer to the zero position for the next application. As a measuring tool, it is necessary to protect the electric torsion wrench. Throwing, shaking and knocking are prohibited

為了確保校準(zhǔn)管理的有效性，有必要參考實際使用現(xiàn)場進行管理，并且要求誤差不受使用場合的影響。 使用前要注意檢查電動扭剪扳手的準(zhǔn)確性，并根據(jù)使用頻率調(diào)整校準(zhǔn)和維護的頻率。 通常每年不少于一次，利用維護管理手段保證電動扭剪扳手的準(zhǔn)確性。等。

 In order to ensure the effectiveness of calibration management, it is necessary to refer to the actual use site for management, and the error is not affected by the use site. Before use, pay attention to check the accuracy of the electric torque wrench, and adjust the frequency of calibration and maintenance according to the use frequency. Generally, it is not less than once a year, and maintenance management measures are used to ensure the accuracy of the electric torque wrench. Etc.
