Shunt Calibration for full bridge

[dineshmech]

I recently started working on strain gage measurements on engine components such as exhaust manifolds, strain gage shafts, rocker levers etc. One of my dilemma is the shunt calibration for different bridge configuration such as torsional bridge configuration to self temperature configuration. It's been a long time since I worked with
wheatstone bridges.. & I find myself relying on our technicians for setting up the instrumentation.
My recent class at Vishay taught me to be suspicious about how we calibrate our bridges.. specially around
what's the right shunt resistance or what will be the effect of leadwire resistance.

Do you know of a website or an excel tool which could help me with calibrating my strain gages?

I noticed the following tools when googled for shunt calibration: (i) Vishay calculator, free but not exhaustive, (ii) Strainmatics (Requires download), (iii) Omega strain calculator, does not cover full bridge.

Your help will be very much appreciated.

Thanks,
