1.在預置式扭力扳手的使用中,要根據(jù)測量工件的要求，選取適中量程的預置式扭力扳手,所測扭力值不可小于扭力器在使用中量程的百分之二十,太大的量程不宜用于小扭力部品的加固,小量程的預置式扭力扳手更不可以超量程使
1. In the use of the preset torque wrench, first of all, according to the requirements of the measuring workpiece, select the preset torque wrench with moderate range, the measured torque value should not be less than 20% of the range of the torque wrench in use, too large range should not be used for the reinforcement of small torque parts, and the preset torque wrench with small range should not exceed the range
2.在使用預置式扭力扳手時,先將扳手方榫連接好輔助配件(如各類批嘴、套筒),確保連接已經(jīng)沒問題。在加固扭力之前,設(shè)定好需要加固的力值,并鎖好緊鎖裝置,調(diào)整好方向轉(zhuǎn)換鈕到加力的方向，然后在使用時先快速連續(xù)操作4-5次，使扳手內(nèi)部組件上特殊潤滑劑能充分潤滑，使預置式扭力扳手更準確，使用。
2. When using the preset torque wrench, first connect the square tenon of the wrench with the auxiliary accessories (such as all kinds of nozzles and sleeves) to ensure that the connection has no problem. Before strengthening the torque, set the force value to be reinforced, lock the locking device, adjust the direction conversion button to the direction of force application, and then quickly and continuously operate for 4-5 times before using, so that the special lubricant on the internal components of the wrench can be fully lubricated, and the preset torque wrench can be used more accurately.
3.測量時,手要把握住把手的,沿垂直于扭力扳手殼體方向，慢慢地加力，直至聽到扭力扳手發(fā)出“塔”的聲音，此時扭力扳手已到達預置扭力值，工件已加力完畢，然后應(yīng)及時解除作用力，以免損壞另部件。在施力過程中,按照國家標準儀器操作規(guī)范,其垂直度偏差左右不應(yīng)超過10度。其水平方向上下偏差不應(yīng)超過3度,操作人員在使用過程中應(yīng)保證其上下左右施力范圍均不超過15度；
3. When measuring, hold the handle by hand and slowly apply force along the direction perpendicular to the shell of the torque wrench until you hear the "tower" sound of the torque wrench. At this time, the torque wrench has reached the preset torque value and the workpiece has been applied force. Then, release the force in time to avoid damaging other parts. During the operation, the verticality of the instrument should not exceed 10. The deviation of the horizontal direction should not exceed 3 degrees, and the operator should ensure that the force application range is not more than 15 degrees in the use process;

4.為了不使測量結(jié)果因水平和垂直方向上的偏差而產(chǎn)生影響,在測量時,應(yīng)在加力把持端上施加一個垂直向下的穩(wěn)定力值， 然后再手動加點力，這樣操作可以讓讀數(shù)值更準確。
4. In order not to affect the measurement results due to the horizontal and vertical deviation, a vertical downward stable force value should be applied on the force application holding end during the measurement, and then the point force should be added manually, so that the reading value can be more accurate.
5.預置式扭力扳手的讀數(shù): 如果是帶表扭力儀器，直接讀取指針所指示的數(shù)據(jù)為測量數(shù)據(jù)值即可；如果是套筒加副刻度指示器，應(yīng)先讀取主刻度上的刻度值,再加上副刻度或微分筒上的刻度值之和為測量數(shù)據(jù)值。
5. Reading of preset torque wrench: if it is a torque instrument with a meter, the data indicated by the pointer can be directly read as the measured data value; if it is a sleeve plus sub scale indicator, the scale value on the main scale shall be read first, and then the sum of the scale values on the minor scale or differential cylinder shall be the measured data value.
6.預置式扭力扳手是測量工具，應(yīng)輕拿輕放，不能代替榔頭進行敲打等不正當行為，不用時請注意將扭力設(shè)為較小值，存放在干燥處。 扭力扳手應(yīng)用范圍較廣,在加固扭力時,相對來講比較簡單，只需要設(shè)定其要求扭力值便可進行操作。
6. The preset torque wrench is a measuring tool, which should be handled with care. It can't replace the hammer for knocking and other improper behaviors. When not in use, please set the torque to a small value and store it in a dry place. Torque wrench has a wide range of applications. When strengthening the torque, it is relatively simple. You only need to set the required torque value to operate.
