Is the torque release clutch there to make sure it is impossible to strain
the mechanism by over tightening or is it to give results that are

measurement was by feel of "first" touch.

It is never impossible, heck, they can drop it. It is an attempt to mechanically put
'feel' into the mic.

I haven't checked but if the user spins the mic closed on part being measured, I'm sure
they can get a different reading regardless of any ratchet or friction system. Inertia
you know.
