You left something out here. You can't just look at the torque-wrench
reading. The harder you pull, the higher the reading. You have to look
at how much deflection you get on the fixture.
Do you mean that you apply a certain amount
of torque, and measure how far the fixture, or the bar of the wrench
deflects, and then apply a correlation factor determined experimentally
to arrive at the cable tension? If so, you have just reinvented the Loos
Tension Gauge! If you just buy the gauge, you can skip all the
experimental
work with the dead weights.
