由于電動扭剪扳手是高頻應(yīng)用工具，為了提高測量精度，有必要定期校準和檢查工具，并配置滿足使用要求的電動扭剪扳手設(shè)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，檢定儀需要定期檢查。由于校準環(huán)境是試驗室環(huán)境，因此與現(xiàn)場操作環(huán)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(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確性，并根據(jù)使用頻率調(diào)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。
As the electric torsional shear wrench is a high-frequency application tool, in order to improve the measurement accuracy, it is necessary to calibrate and check the tool regularly, and configure the electric torsional shear wrench equipment that meets the use requirements. At present, the electric torsional shear wrench is mainly calibrated by the calibrator, and the calibrator needs to be checked regularly. Since the calibration environment is a laboratory environment, it is very different from the field operation environment. 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 occasion. Before use, pay attention to check the accuracy of the electric torsion shear wrench, and adjust the calibration and maintenance frequency according to the use frequency. Usually at least once a year, use maintenance and management means to ensure the accuracy of electric torsion shear 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，在施加過程中需要預(yù)先設(shè)置固定扭矩值。當達到設(shè)定值時，電動扭剪扳手將發(fā)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(xù)施加力。請勿使用沖擊力，停止施加力后，各個零件復(fù)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(yīng)在±15°以內(nèi)（垂直方向和水平方向）。
Electric torque shear wrench is mainly used to install fasteners, such as bolts, screws and nuts. Through torque control, the tightening of the thread is ensured, and the thread will not be damaged due to excessive torque. Therefore, it is necessary to use the electric torsion shear wrench to fix the torque value, and the fixed torque value needs to be set in advance during the application process. When the set value is reached, the electric torsion shear wrench will send out a reminder 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 middle scale line of the handle of the electric torsion shear wrench, and apply force only in the direction indicated by the electric torsion shear 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，看指針是否在零標度值上，如果不是則需要對其進行調(diào)整。為確保讀數(shù)準確，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。
A wrench with appropriate range shall be used according to the strength and torque of fasteners, and it is not allowed to exceed the application range of the wrench. The wrench needs to be zeroed before use. When there is no load, pay attention to the inspection of the pointer of the torque wrench to see whether the pointer is on the zero scale value. If not, it needs to be adjusted. In order to ensure accurate reading, hold the handle of the wrench with one hand during use, keep the torque wrench at right angles to the tension, and apply force stably. When the pointer points to the torque value, do not apply too much force, otherwise the error value will appear. After the measurement, turn the knob to return the pointer to zero for the next application. As a measuring tool, care must be taken to protect the electric torsion shear wrench. Throwing, shaking and knocking are prohibited.
