arter-bridge sensor to each channel. Each
channel has an EXC terminal that provides the excitation voltage

s, an AI terminal that meas

res the bridge voltage, and an
RC terminal that provides the q
u
arter-bridge completion. Refer to

arter-bridge
sensors to the NI 9235/9236.

Quarter-Bridge Connections for 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.
