Torque wrench miscalibrated
Torque wrench miscalibrated
(OP)
Hello everybody:
When a torque wrench is miscalibrated, let us say in 20 N.m, is it technically accepted to add/to diminish that amount to the required torque value at the time of using it?

Ideally, the relationship is equality, but that is not a necessity.
So, if you know what to set the dial to in order to get what you want then yes, that is "technically accepted".
I would not trust the average technician to do this correctly, and would not allow it on anything that I was paying for.

If the latter, then how do you know it's not still wearing, and the offset not shifting further? Answer: recalibrate again...and what do you do about the assembly shipped after calibrating last week, when the calibration is unacceptably shifted this week...
