<VV> RE: torque wrench

[srmarti]

Not knowing exacting how the calibrator is built or calibrated, I can't
comment on the accuracy.  I don't see how it's so complicated to check.
Clamp a socket in a vise and hang the wrench handle horizontally and hang a
weight off it.   Weight times handle length equals torque (close enough,
know I'm neglecting handle weight etc.) See if wrench torque indication
agrees.
