Precautions for operation with fixed torque electric wrench

Matters needing attention in the operation of fixed torque electric wrench

1.The size of the bolt diameter has a certain effect on the control accuracy.The same type of bolt connection should be used to calibrate the torque value during construction,and it should be checked and calibrated after a period of use.
