How To Re-calibrate A Torque Wrench. First, measure the distance from the center point on the wrench head to the point at which you apply the most pressure on the wrench. There is no black and white answer but the usual rule of thumb is around 5000 cycles or every 12 months.
Then clamp the wrench bit in the vise. 3 general care of the tool during storing and usage “ It is advisable to bring the wrench in to a calibration lab on an annual basis or after every four to five thousand cycles.
There is no black and white answer but the usual rule of thumb is around 5000 cycles or every 12 months.
To perform a torque wrench calibration on your own, you need to determine the calibration ratio and multiply that amount by the required bolt torque. In all cases the torque wrench should be used to apply torque to the calibration device until the required test reading is obtained on the calibration device and the reading on the torque wrench is noted at this point. To calibrate a torque wrench, you have to setup a known torque and adjust the wrench to correctly act at that setting (ie: Should be calibrated if dropped.
