ft-lb (0.25 to 4.0 times Full Scale Torque; with no scaling, Tref = Tfs)
Set System Gain on RX10K receiver to this value
Verify the Output
Recommended


NOTE: Valid for 350 ohm strain gage only. Deviation in the actual Voltage Output or Displayed Value from the Calculated Output value with shunt applied is not an indication of overall system accuracy. Shunt is placed in parallel with one leg of the bridge, exaggerating error that is cancelled in the full bridge circuit. However, Voltage Output should be within +/-1% of the calculated value.

Equations
`"Full Scale Torque", T_(FS)=(V_(FS)*pi*E*4*(D_O^4 - D_I^4))/ (V_(exc)*GF*N*192*(1+v)*G_(xmt)*D_O)`
`"System Gain", G_S = (T_(fs)/T_(ref)) * G_(xmt)`
`"Sensitivity", S = T_(ref)/10`
`"Voltage Output", V = (T/T_(ref)) * V_(fs)`
