A. Rotating the case or the knob on the case can drive the pointer to rotate. The pointer is a memory pointer, which is called a passive pointer or a driven pointer; The pointer connected with the movement is the working pointer, also known as the active pointer.

B、使用本产品应根据紧固件的强度等级和扭矩值要求选用量程的规格和型号，不应超范围使用。表盘式刻度扭矩扳手使用前需调整零位：

B. When using this product, the specification and model of the range shall be selected according to the strength grade and torque value requirements of fasteners, and shall not be used beyond the range. Dial type graduated torque wrench shall be adjusted to zero position before use:

A、右旋使用时：顺时针旋转表盖上的旋钮，使记忆指针与主动指针指向刻度盘的零位刻线。

A. Right hand 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.

B、左旋使用时：逆时针旋转表盖的的旋钮，使记忆指针与主动指针靠紧，且主动指针指向刻度盘的零位刻线。

B. 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.

表盘式刻度扭矩扳手使用时注意：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，直至记忆指针指向所需的扭矩值。

When using dial type graduated torque wrench, pay attention to: 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.

表盘式刻度扭矩扳手使用结束后：表盘式刻度扭矩扳手停止施力后，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，可进行下使用。

After the dial type graduated torque wrench is used: after the dial type graduated torque wrench stops applying force, the active pointer automatically returns to zero under the action of elastic element and movement torsion spring, the memory pointer still stays on the indicated scale and accurately reads out the torque value. Rotate the knob on the meter cover to return the memory pointer to the zero position, which can be used in the next step.
