If you connect floating signals to the NI 9237, NI recommends connecting the EX- signal to the earth ground or shield for better noise rejection.
- Page 14 EX- signal to the earth ground or shield for better noise rejection. Bridge Calibration When you insert or remove a new sensor from the NI 9237, slight changes in the excitation voltages can cause a mismatch between the internal half-bridge completion resistors and the half-bridge sensors, which results in a change in the measurement offsets.

- Page 16 NI 9237 Ensure that neither the TEDS data (T+) nor the TEDS return (T-) signal is tied in common to any AI signals on the NI 9237. The NI 9237 connects all the T- signals together internally. The NI 9237 with DSUB has only three T- pins. To connect four TEDS sensors to the NI 9237 with DSUB, wire the TEDS return signals of two of the sensors to one of the T- pins.
