Function: The torque wrench is an instrument indicator for measuring the torque of threaded fasteners, which can be tested arbitrarily within the range. Suitable for fastener torque testing with high precision requirements From the pointer still staying on the indicating scale value, the torque value can be accurately read. Rotate the knob on the top of the dial to reset the slave pointer to zero for use. Wrench shape: combination wrench Wrench head type: fixed ratchet head Scale display mode: window display scale Minimum torque: 0 (m) Maximum torque: 100 (m) 1. The zero position must be adjusted before use. 2. When using, apply tightening force slowly and steadily until the driven pointer reaches the required torque value. 3. After the force is stopped, the active pointer will automatically return to zero. Precautions: 1. Do not disassemble or knock at will, so as not to affect the accuracy of the product. 2. Avoid contact with high temperature to avoid damage. 3. Do not use beyond the torque range. colour:Black+silver Material:Metal Package Contents: 2 x digital torque wrench Only the above package content, other products are not included.
