In the use of the torque wrench,Torque wrenchFirst according to the requirements of CeLiangBu product selection moderate range, the measured torque value is less than twenty percent of the torsion device in use range, should not be too great a range for small torsion part of reinforcement, small range of torsion is less can outrange use;

1.In the use of the torque wrench, the first thing to moderate selection according to the requirement of the CeLiangBu product range, the measured torque value is less than twenty percent of the torsion device in use range, should not be too great a range for small torsion part of reinforcement, small range of torsion is less can outrange that;

2. When using torque wrench, first connect the stress pawl good auxiliary accessories (e.g., sleeve, all kinds of batch of mouth), ensure that the connection has no problem.Before strengthening torsion, set need reinforcement force value, and lock the lock device, and then adjust the direction the direction of the convert button to strength;

3. The measurement, hand to grasp the handle range, slowly along the direction perpendicular to the pipe shaft torque until after hearing to have set the value of the sound.According to the national standard in the process of applying, instrument operation specification, about its verticality deviation should not be more than 10 degrees.The horizontal deviation shall not be more than 3 degrees from top to bottom, our factory is in use process operators should ensure that the levels of force application scope are not more than 15 degrees;

4. In order not to make the deviation of measurement results for the horizontal and vertical direction and effect, when measuring should be applied on the strength of end of a vertical downward stable strength;

5. The reading of the torque wrench: if it is with table torsion instrument, directly read pointer indicated data to measure value;Sleeving and if it is a dial indicator, should first read the scale value on the scale, scale and vice or differential cylinder on the scale value to measure the sum of the data values.
