Yo u can connect a quarter-bridge sensor to each channel. Each
channel has an EXC terminal that provides the excitation voltage
stimulus, an AI terminal that measures the bridge voltage, and an
RC terminal that provides the quarter-bridge completion. Refer to
Figure 2 for an illustration of how to connect quarter-bridge
sensors to the NI 9235/9236.

* For best system accuracy, set up the connections to EXC and RC with
equal lengths of an identical wire type and gauge.
** For best system accuracy, set up the connection to AI directly at the
sensor instead of shorting AI to RC directly at the terminals.
