1、 Before using the torque wrench, the specification and model of appropriate range shall be selected according to the strength grade and torque value requirements of fasteners, and it shall not be used beyond the range. When using right rotation, rotate the knob on the meter cover clockwise to make the memory pointer and active pointer point to the zero mark of the dial. When using left-hand rotation, rotate the knob of the meter cover counterclockwise to make the memory pointer close to the active pointer, and the active pointer points to the zero mark of the dial.

]二、在使用时，将指针扳手的方榫与紧固件对接(根据需要可直接对接，也可通过转接套筒对接)，然后缓慢平稳地施加扳拧力，直记忆指针指向所需的扭矩值。

]2、 When in use, butt the square tenon of the pointer wrench with the fastener (butt directly or through the adapter sleeve as required), and then slowly and stably apply the pulling force until the memory pointer points to the required torque value.

三、在停止施力后，主动指针在弹性元件和机芯扭簧的作用下自动回复零位，记忆指针仍停留在指示的刻度上，并准确读出扭矩值。旋转表盖上的旋钮，使记忆指针也回复到零位，可进行下一次使用。精量在使用时，还进行定期的检查和校正。

3、 After stopping the force application, the active pointer will automatically return to the zero position under the action of the elastic element and the movement torsion spring, the memory pointer will still stay on the indicated scale and accurately read out the torque value. Rotate the knob on the meter cover to return the memory pointer to the zero position for the next use. When the precision is used, it is also checked and corrected regularly.
