1、用戶可在50-3500N.m的范圍內任意選擇相應規格的電動定扭力扳手。
1. The user can choose the corresponding electric constant torque wrench in the range of 50-3500n. M.
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 panel of the controller. It is engraved with 0-10 scale values. The function of fine adjustment knob is to adjust and compensate between two gears of rough adjustment, so as to improve the precision of torque control. (see following page)
3、調節方法：國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: domestic products are provided with torque test data card when they leave the factory for reference when users calibrate. Users can select a certain scale value according to the required torque, tighten the bolts according to the operation method of tightening bolts, and measure the actual torque value of bolts with force measuring wrench or other force measuring instruments. If the torque difference is small, fine adjustment can be used to compensate; if the difference is large, coarse adjustment can be made Up or down one gear, repeated several times can obtain the required torque value.
操作注意事項：
Operation precautions:
1、螺栓直徑的大小對控制精度有一定的影響，施工中應用相同型號的螺栓連接付來標定扭矩值，而且使用一段時間后還應進行檢驗校定。
1. The size of the bolt diameter has a certain impact on the control accuracy. In construction, the same type of bolt connection pair is used to calibrate the torque value, and the inspection and calibration should be carried out after a period of use.
2、工作前應開機空轉3-5分鐘。操作中如發現電機火花大，聲音異常，扭矩不穩定時，應立即停機檢查，切勿帶病工作。
2. Start the machine for 3-5 minutes before operation. In case of large spark, abnormal sound and unstable torque of the motor during operation, stop the machine immediately for inspection, and do not work with diseases.
3、定期清洗和更換油脂，一般在工作5000次后，應進行一次清洗加油，以延長使用壽命。
3. Regular cleaning and replacement of grease, generally after 5000 times of work, should carry out a cleaning and refueling, in order to extend the service life.
4、主機上的電源開關，碳刷，控制儀上的保險絲等均屬易損件，容易引起故障，應經常檢查，及時更換。
4. The power switch, carbon brush and fuse on the controller are all vulnerable parts, which are easy to cause failure. They should be checked frequently and replaced in time.
5、使用中如發現工具上的螺釘松動，應及時緊固。
5. If it is found that the screw on the tool is loose, it should be tightened in time.
6、搬運工具時不可提拉電纜線，并注意輕拿輕放，防止震動和摔碰。不用時應放在通風干燥處。如發現受潮應及時進行干燥處理。不可與酸、堿等有害物質氣體接觸或存放在一起。
6. When handling tools, do not pull the cable, and pay attention to handle with care to prevent vibration and collision. When not in use, it should be placed in a ventilated and dry place. In case of damp, dry it in time. Do not contact or store with acid, alkali and other harmful substances.
