手動扭矩扳手正確使用方法有哪些 扭矩扳手也叫做力矩扳手， 下面 介紹音晌式扭矩扳手使用注意事項： (1)設定所需的扭矩值，并將鎖緊裝置撥 lock 位置。 (2)請從小值往大值方向調整扭矩，若超過設定值，請往回調低于設定扭 矩值后再調。 (3)請勿直接從大值調小值。 (4)檢查扭矩扳手驅動頭是否適合，或選用合適的轉接頭。扭力扳手的用法（1）所選用的扭力扳手的開口尺寸一定要與螺栓或螺母的尺寸相符合，扳手開口過大易滑脫并損傷螺件的六角，在進口汽車維修中，應注意扳手公英制的選擇。 (5)施力前需確定扳手與被施力的物體確實結合。 (6)施力位置為握把正。 (7)施力應平穩緩慢，聽到音響(即待彈簧釋放)后，即停止施力。 (8）使用后需將設定值轉回小刻劃。 (9)使用大扭矩扳手時，操作者需注意身體。
What are the correct ways to use manual torque wrenches? Torque wrenches are also called torque wrenches. Here are the precautions for the use of sound torque wrenches: (1) set the required torque value and turn the locking device to the lock position. (2) Please adjust the torque from small value to large value. If it exceeds the set value, please adjust it back to lower than the set torque value before adjustment. (3) Do not directly adjust from large value to small value. (4) Check whether the driving head of the torque wrench is suitable, or select a suitable adapter. Usage of torque wrench (1) the opening size of the selected torque wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it is easy to slip off and damage the hexagon of the screw. In the maintenance of imported vehicles, attention should be paid to the selection of metric and inch system of the wrench. (5) Before applying the force, it is necessary to make sure that the wrench is indeed combined with the object to be applied. (6) The force application position is the center of the grip. (7) The force shall be applied steadily and slowly. After hearing the sound (i.e. waiting for the spring to release), the force shall be stopped. (8) After use, it is necessary to turn the set value back to the small score. (9) When using a large torque wrench, the operator should pay attention to his body.

4、檢查中點，高點數值是否準確。
4. Check whether the midpoint and high point values are accurate.
調整輪加4圈即40Nm，此時扭力扳手應為60Nm，通過看檢定儀數據看扭力扳手數值是否準確，繼續操作調整輪順時針擰4圈，到100Nm，查看數值，進行微調。
Add 4 turns to the adjusting wheel, i.e. 40nm. At this time, the torque wrench should be 60NM. Check whether the torque wrench value is accurate by looking at the data of the calibrator. Continue to operate the adjusting wheel, turn it clockwise for 4 turns to 100nm, check the value, and make fine adjustment.
5、回低點，調整輪對齊零點，撥動標尺。
5. Return to the low point, adjust the wheel to align the zero point, and move the ruler.
調整輪相應減8圈，如檢定儀數據準確，為20Nm，滿足±4%的誤差，拿掉調整輪，用調整輪0刻度位置對準低點，并撥動標尺20Nm位置，上緊扭緊手柄，裝上螺紋擋銷，校驗孔貼上校驗標志。
Adjust the wheel by 8 turns. If the data of the calibrator is accurate, it is 20nm, meeting the error of ± 4%, remove the adjusting wheel, align the low point with the 0 scale position of the adjusting wheel, move the scale to the position of 20nm, tighten the handle, install the threaded retaining pin, and paste the calibration mark on the calibration hole.
