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
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
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）。
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。
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.
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
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
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。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.
