Also, the torque wrench is only accurate when your hand is on the Handle. If you try pulling on the wrench somewhere like in the middle of its shaft, then it will torque higher than what you set it at. It is important to apply the force only to the handle. If its has a black grip or rough metal surface at the end of the wrench, then only put your hand there to pull or push the wrench.
Also, I always let it click 2 or 3 times just to make sure it is correct. I will apply force to the wrench until it clicks, then I will let up, then apply force again, let it click, etc. Sometimes you might be pulling/pushing it kinda sideways or there may be debris in the threads of the bolt, so I like to double or triple check that the wrench is clicking at the same place.
