由于電動扭剪扳手是高頻應用工具，為了提高測量精度，有必要定期校準和檢驗工具，并配置滿足使用要求的電動扭剪扳手設備。 目前，電動扭剪扳手主要由檢定儀對電動扭剪扳手進行校準，檢定儀需要定期檢驗。 由于校準環境是試驗室環境，因此與現場操作環境有很大的不同。 為了確保校準管理的有效性，有必要參考實際使用現場進行管理，并且要求偏差不受使用場合的影響。 使用前要注意檢驗電動扭剪扳手的準確性，并根據使用頻率調整校準和維護的頻率。 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確性。

Due to the fact that electric torque wrench is a high-frequency application tool, in order to improve measurement accuracy, it is necessary to regularly calibrate and inspect the tool, and equip it with electric torque wrench equipment that meets usage requirements. At present, electric shear wrenches are mainly calibrated by calibration instruments, which require regular inspection. Due to the fact that the calibration environment is a laboratory environment, it is significantly different from the on-site operating environment. In order to ensure the effectiveness of calibration management, it is necessary to refer to the actual usage site for management and require that deviations are not affected by the usage situation. Before use, pay attention to checking the accuracy of the electric torque wrench and adjust the calibration and maintenance frequency according to the frequency of use. Usually, at least once a year, maintenance and management measures are used to ensure the accuracy of the electric torsion wrench.

電動扭剪扳手的準確使用方法：

Accurate usage method of electric torsion wrench:

電動扭剪扳手主要用于安裝緊固件，例如螺栓，螺釘和螺母。 通過扭矩控制，確保了螺紋的擰緊，并且不會因扭矩過大而損壞螺紋。 因此，有必要使用電動扭剪扳手進行扭矩值固定操作，在施加過程當中需要預先設置固定扭矩值。 當達到設定值時，電動扭剪扳手將發出提醒信息，可以感覺到手部振動或聽到“喀噠”聲，即扭矩已完成。 當扭矩值達到固定位置時，無需繼續施加力。 請勿使用沖擊力，停止施加力后，各個零件復位。 施加扭矩時，將手握在電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，同時施力方向應在±15°以內（垂直方向和水平方向）。

Electric torque wrench is mainly used for installing fasteners, such as bolts, screws, and nuts. By torque control, the tightening of the threads is ensured and the threads are not damaged due to excessive torque. Therefore, it is necessary to use an electric torque wrench to fix the torque value, and the fixed torque value needs to be pre-set during the application process. When the set value is reached, the electric torque wrench will emit a reminder message, indicating that the torque has been completed by feeling hand vibration or hearing a "click" sound. When the torque value reaches a fixed position, there is no need to continue applying force. Do not use impact force. After stopping the application of force, all parts should be reset. When applying torque, hold your hand on the middle scale line of the electric torque wrench handle and apply force only in the direction indicated by the electric torque wrench. The direction of application should be within ± 15 ° (vertical and horizontal).

根據緊固件的強度和扭矩用以使用合適量程的扳手，并且不允許高于扳手的適用范圍。扳手在使用前需要調零，無荷載時注意對扭矩扳手指針的檢驗，看指針是否在零標度值上，如果不是則需要對其進行調整。 為確保讀數準確，在使用過程當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，并穩定地施加力。 當指針指向扭矩值時，禁止用力過大，否則會出現偏差值。 測量結束后，旋轉旋鈕將指針返回到零位，以便進行下一個應用。 作為測量工具，必須注意保護電動扭剪扳手。禁止進行扔擲、震動以及敲擊等。

Use a wrench with an appropriate range based on the strength and torque of the fastener, and do not allow it to exceed the applicable range of the wrench. The wrench needs to be zeroed before use. When there is no load, pay attention to checking the torque wrench pointer to see if it is on the zero scale value. If it is not, it needs to be adjusted. To ensure accurate readings, it is necessary to hold the handle of the wrench with one hand during use, keeping the torque wrench and tension at a right angle, and applying force steadily. When the pointer points to the torque value, do not apply too much force, otherwise a deviation value may occur. After the measurement is completed, rotate the knob to return the pointer to the zero position for the next application. As a measuring tool, it is necessary to pay attention to protecting the electric torsion wrench. Throwing, shaking, and striking are prohibited.
