The selection of torque wrenches

1. use dial indicating torque wrenches to take into account the following factors
Torque wrench selection should be based on the torque value, set the torque value should be kept to a torque wrench
Use 1/2~2/3.
Space in the context of the effective length of the 
high strength bolt torque coefficient calibrator.
Meet above 2 points of, should selection weight light of torque wrench, reduced workers of intensity for example: now has a operation space sufficient of station need using set value for 80Nm of set value type ratchet head torque wrench, from East daily with torque wrench information (see schedule) in the, we see can with have torque wrench has QSP100N, and QSP140N, and QSP200N 3 species, which QSP140N, it than QSP100N long, set value in using range of 1/2~2/ 3, weight lighter than QSP200N.Which should ideally be QSP140N
