定扭矩電動扭矩扳手使用方法：
Use method of fixed torque electric wrench:
1、根據(jù)工作所需扭矩值要求，確定預(yù)置扭矩值。
1. Determine the preset torque value according to the required torque value.
2、預(yù)置扭矩值時，將六角調(diào)節(jié)鑰匙插入扳手尾端，然后旋轉(zhuǎn)，調(diào)節(jié)標(biāo)尺刻線所需扭矩值。調(diào)節(jié)好后，將鑰匙拉出。
2. When presetting the torque value, insert the hexagonal adjusting key into the end of the wrench, then rotate and adjust the ruler's marking to the required torque value. After adjusting, pull out the key.
3、在扳手方榫上裝上相應(yīng)套筒，并套住緊固件，再在手柄上平穩(wěn)地施加扭矩額定扭矩。當(dāng)擰緊到發(fā)出信號“嗒”的一聲（已達(dá)到預(yù)置扭矩值）止，一次作業(yè)完畢。
3. Install the corresponding sleeve on the square tenon of the wrench, and cover the fastener, then apply the torque to the rated torque smoothly on the handle. When tightened to the signal "click" (reached the preset torque value), one operation is completed.
力矩扳手選購參數(shù)標(biāo)準(zhǔn)
Standard for Selection and Purchase Parameters of Torque Spanners
1、手柄人體工程學(xué)優(yōu)化設(shè)計，握持舒適，大大降低高強(qiáng)度操作 力矩扳手 時產(chǎn)生的疲勞感。
1. Optimum design of handle ergonomics, comfortable grip, greatly reducing the fatigue of high-strength operating torque wrench.
2、雙刻度尺，可精確設(shè)定扭矩值。
2. Double scale, which can accurately set the torque value.
3、達(dá)到設(shè)定扭矩值時，發(fā)出清晰的報訊聲，并且在手柄上可感覺到輕微震動。
3. When the set torque value is reached, a clear signal is emitted and a slight vibration can be felt on the handle.
4、鎖定環(huán)靠近虎口處，可避免誤操作改變設(shè)定扭矩值。
4. Locking ring is close to tiger mouth, which can avoid misoperation and change the set torque value.
5、扳手長度：990MM。
5. Spanner length: 990MM.
6、驅(qū)動方尺寸3/4英寸。
6. Driver size is 3/4 inch.
7、比較小刻度間隔1。
7. Minimum scale interval 1.
8、應(yīng)用力矩應(yīng)在扳手的扭力范圍40%90%之內(nèi)。
8. The applied torque should be within 40% to 90% of the wrench's torsion range.
9、按扭力要求鎖緊螺母。
9. Lock nuts according to torsion requirement.
