How To Calibrate A Digital Torque Wrench. A torque wrench tester will display this value during checking or calibration. For most customers, this means you should calibrate and test torque wrenches every 12 months.
Check if your torque wrench clicks when it reaches the torque level you calculated in step three. “ts” stands for torque setting. The torque wrench measures the torque as a proxy for the tension on a bolt, which could suffer from inaccuracy if the wrench isn’t calibrated correctly.
Due to manufacturing tolerances, even if the wrench is used correctly, the actual torque applied by the tool may be different from the value set on the scale.
The actual click from a wrench is considered a cycle of that wrench. This avoids the need for businesses to invest in and maintain testing and calibration equipment, or dedicate internal resource to testing, calibrating and documenting the process. 1) you should do the measurement starting from the square drive head and follow the instrument to the handle.
