電動扭矩扳手結構新穎、體積小、重量輕、可靠。由于采用靜扭結構，運轉平穩，無振動、無沖擊，噪音小，操作者不受反力矩的影響，因而勞動強度低。額定電壓220V50/60Hz 精度±5%。
Electric torque wrench has novel structure, small volume, light weight, safety and reliability. Due to the use of static torsion structure, smooth operation, no vibration, no impact, low noise, the operator is not affected by the counter torque, so the labor intensity is low. Rated voltage 220V50 / 60Hz accuracy ± 5%.
電動扭力扳手應用行業：
Electric torque wrench application industry:
電動扭矩扳手廣泛應用于栓焊結構橋梁的架設，廠房、塔架及化工、冶金、發電設備的安裝。大型機械、起重設備和車輛裝配作業，以及對螺紋緊固件的扭矩及軸向拉力有嚴格要求的場合。
Electric torque wrench is widely used in the erection of bolt welded structure bridges, the installation of factory buildings, towers and chemical, metallurgical and power generation equipment. Large machinery, lifting equipment and vehicle assembly operations, as well as occasions with strict requirements for torque and axial tension of threaded fasteners.
電動扭矩扳手螺栓的擰緊操作
Tightening operation of bolts of electric torque wrench
1、裝上反力支架，并緊固螺釘。開動主機，使方頭銷孔與反力支架孔相對應，然后裝入扳手套筒，插上銷釘，并用橡膠圈固定。
1. Install the reaction support and tighten the screws. Start the main engine, make the square head pin hole correspond to the reaction support hole, then install the wrench socket, insert the pin, and fix it with the rubber ring.
2、將控制儀的扭矩旋鈕調到所需扭矩值，將主機正反開關撥到正轉位置，把扳手套筒套在螺紋連接件的六方上。
2. Adjust the torque knob of the controller to the required torque value, turn the positive and negative switch of the main engine to the positive rotation position, and put the wrench socket on the hexagon of the threaded connection piece.
3、按下電源開關，扳手啟動。當反力支架力臂靠牢支架時（支點可以是鄰近的一只螺栓或其他可作支點的位置）螺栓開始擰緊。當螺栓扭矩達到預定扭矩時，扳手自動停止，緊固完成，松開電源開關，進行下一只螺栓的擰緊工作。
3. Press the power switch to start the wrench. When the reaction support arm is against the support (the fulcrum can be an adjacent bolt or other position that can be used as a fulcrum), the bolt starts to be tightened. When the bolt torque reaches the preset torque, the wrench will stop automatically, the tightening is completed, the power switch will be loosened, and the next bolt will be tightened.
4、扳手自動停止后，靠反力支架的彈性形變力，使支架力臂自動脫離支點，取下扳手。如力臂不能脫離支點時，可撥動正反開關，點動電源開關扳手即可取下。
4. After the wrench stops automatically, the elastic deformation force of the counter force bracket makes the bracket force arm automatically separate from the fulcrum, and the wrench is removed. If the force arm cannot be separated from the fulcrum, the forward and reverse switch can be turned, and the power switch wrench can be inched to remove.
電動扭力扳手扭矩的選擇與調節
Selection and adjustment of torque of electric torque wrench
1、用戶可在50-3500Nm的范圍內任意選擇相應規格的電動扭力扳手。
1. The user can choose the electric torque wrench of corresponding specification in the range of 50-3500nm.
2、控制儀面板上有“扭矩調解旋鈕”。刻有0-10個刻度值。細調旋鈕的作用是在粗調兩檔之間進行調節補償，以提高扭矩控制精度。（見后頁）
2. There is a "torque adjustment knob" on the control panel. Engraved with 0-10 scale values. The function of fine adjustment knob is to adjust and compensate between two gears of coarse adjustment, so as to improve the accuracy of torque control. (see next page)
3、調節方法：產品出廠時帶有扭矩測試數據卡片，供用戶標定時參考，用戶可根據所需扭矩選擇某一刻度值，按擰緊螺栓的操作方法，擰緊螺栓，用測力扳手或其它測力儀器測出螺栓的實際扭矩值，若扭矩相差較小，可用細調加以補償，若相差較大，可將粗調向上或向下調一檔，反復幾次即可獲得所需扭矩值
3. Adjustment method: the product is provided with a torque test data card for the user's reference during calibration. The user can select a certain scale value according to the required torque, tighten the bolt according to the operation method of tightening the bolt, and use a force measuring wrench or other force measuring instruments to measure the actual torque value of the bolt. If the torque difference is small, fine adjustment can be used to compensate. If the difference is large, coarse adjustment can be made upward Or downshift one gear for several times to obtain the required torque value
