Some trouble with my SCXI 1520 module Using MAX4

[mca]

Hi !
I connected a full bridge Strain gauge   to the SCxi 1520 module but  now i got some problems  .
1-do I have to set the gain of the amplifier first( can't see how)and then create the scale  or it is not necessary
2-how can I calculate the shunt resistance( I am using 4 resistances of 350 ohm for the full bridge), do i have to do this or it is done automatically .



I will appreciate your help
Thank u

Problems 2:

Each input channel of the SCXI-1520 includes two independent shunt calibration circuits, with which you can simulate two separate loading effects on your strain-based device and compensate for any possible gain errors.

The RN-55 style shunt calibration resistors are in sockets
and located in the SCXI-1314 front-mounting terminal block.

You enable or disable the shunt resistors through software commands.

Looks like u have not understood the funda of shunt cal

read this link to understand about strain measurement and shunt cal
