Just curious, how do you calibrate the torque adapter?  Digital or not, it
is still measuring the deflection of a spring, just like most torque
wrenches do.

I couldn't even find an accuracy spec on the Sears site, but the
instructions for the one Eastwood sells say "Periodic re-calibration may be
necessary to maintain accuracy.".
