Dear Simone,
the ratio sensor can be connceted to the STGM slice like shown in the connection diagram below:
Excitation voltage has to be set to 5V.
The scailing will be unusual because the IN- is connected to the Vref. The measurement result will be displayed between 2V and -2V, but with the help of mathematics this can also be fixed. The connection abowe is better because it is best to use the sensors reference voltage than the GND from the amplifier, therefore connecting the IN- on the VrefOUT than on the amplifiers GND.
Kind regards.
