2 steps on using craftsman torque wrench. They mount to a threaded rod that runs into the main shaft. To calibrate a torque wrench, start by measuring the distance from the square drive to the handle to the.
2.6 turn the nut or bolt manually until it catches the screw thread Place the wrench on a lug nut that belongs to any equipment. Press and hold pwr + unit until cal appears, then release buttons.

First, place a socket on the wrench and secure it. Since torque is force * distance, we simply do a bit of math and setup a lever and weight. 2.5 work on the nuts and bolts;
Btw i found out that the ratchet mechanism depends a lot on the tightness of the torx screw on the head.
