The manual that comes with my Sears MicroTork says this: "When the wrench is not in use, keep it set below 25% of capacity. If you leave the wrench set at a reading of more than 50% capacity for more than a few hours, set the wrench at its lowest setting and leave it there for a few minutes before using it again."
I infer from this that the lower the storage setting the better, although benefits of storing at 0% capacity are apparently not significantly greater than storing at 24%.
Since it's clearly being left to me to decide between 0% and 24% as I see fit, I see fit to impose zero deformation on the spring in my torque wrench rather than some deformation. Except for, of course, the danger that I may loosen that famous locknut unless I'm very careful or stop turning a click or three short of the bottom...
