扭剪电动扭力扳手的维护：

Maintenance of electric torque wrench for torsion shear:

由于扭剪电动扭力扳手是高频应用工具，为了提高测量精度，有必要定期校准和检查工具，并配置满足使用要求的电动扭剪扳手设备目前，电动扭剪扳手主要由检定仪对电动扭剪扳手进行校准，检定仪需要定期检查由于校准环境是试验室环境，因此与现场操作环境有很大的不同为了确保校准管理的有效性，有必要参考实际使用现场进行管理，并且要求误差不受使用场合的影响使用前要注意检查电动扭剪扳手的准确性，并根据使用频率调整校准和维护的频率通常每年不少于一次，利用维护管理手段保证电动扭剪扳手的准确性

Due to the high-frequency application of electric torque wrenches, it is necessary to regularly calibrate and inspect the tools in order to improve measurement accuracy, and equip them with electric torque wrench equipment that meets usage requirements. Currently, electric torque wrenches are mainly calibrated by calibration instruments, which need to be checked regularly. As the calibration environment is a laboratory environment, Therefore, there is a significant difference 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 it is required that errors are not affected by the usage situation. Before use, attention should be paid to checking the accuracy of the electric torque wrench, and the calibration and maintenance frequency should be adjusted according to the frequency of use. Generally, the frequency of calibration and maintenance should not be less than once a year. Maintenance management methods should be used to ensure the accuracy of the electric torque wrench

扭剪电动扭力扳手的正确使用方法：

The correct usage of electric torque wrench for torsion shear:

电动扭剪扳手主要用于安装紧固件，例如螺栓，螺钉和螺母通过扭矩控制，确保了螺纹的拧紧，并且不会因扭矩过大而损坏螺纹因此，有必要使用电动扭剪扳手进行扭矩值固定操作，在施加过程中需要预先设置固定扭矩值当达到设定值时，电动扭剪扳手将发出提醒信息，可以感觉到手部振动或听到喀哒声，即扭矩已完成。 当扭矩值达到固定位置时，无需继续施加力。 请勿使用冲击力，停止施加力后，各个零件复位。 施加扭矩时，将手握在电动扭剪扳手手柄的中间刻度线上，并仅在电动扭剪扳手指示的方向上施加力，同时施力方向应在±15°以内（垂直方向和水平方向）。

Electric torque wrench is mainly used for installing fasteners, such as bolts, screws, and nuts. Through torque control, it ensures the tightening of threads and does not damage them due to excessive torque. Therefore, it is necessary to use an electric torque wrench for torque value fixing operation. During the application process, the fixed torque value needs to be pre-set. When the set value is reached, the electric torque wrench will send a reminder message, You can feel hand vibration or hear a clicking sound, indicating that the torque has been completed. 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, while the direction of application should be within± 15° Within (vertical and horizontal directions).

根据紧固件的强度和扭矩用以使用合适量程的扳手，并且不允许超过扳手的适用范围。扳手在使用前需要调零，无荷载时注意对扭矩扳手指针的检查，看指针是否在零标度值上，如果不是则需要对其进行调整为确保读数准确，在使用过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，并稳定地施加力当指针指向扭矩值时，禁止用力过大，否则会出现误差值测量完成后，旋转旋钮将指针返回到零位，以便进行下一个应用作为测量工具，必须注意保护电动扭剪扳手。禁止进行扔掷、震动以及敲击等

Use a wrench with an appropriate range based on 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 checking the torque wrench pointer to see if it is on the zero scale value. If it is not, adjust it to ensure accurate reading. During use, hold the handle of the wrench with one hand to maintain a right angle between the torque wrench and the pulling force, and apply force steadily. When the pointer points to the torque value, do not use too much force, otherwise errors 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, attention must be paid to protecting the electric torsion wrench. Throwing, shaking, and striking are prohibited
