R_GAIN's value should be chosen so that a positive full scale of the instrument produces 10V at
the analog input of the X-MCB1 and a negative full scale produces 0V. The OP97 op-amp
provides an offset of 5V to the amplified value so that no load on the instrument produces an
output of 5V.

The reference circuit below demonstrates interfacing a thermocouple to the X-MCB1. Depending
on the application, an offset voltage may need to be provided.
