NI 9237E Operating Instructions and Specifications
Note
When you insert or remove a new sensor from the
NI 9237E, 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.
National Instruments recommends performing bridge
calibrations of quarter- or half-bridge sensors after
connecting all sensors to the NI 9237E and after
removing or attaching any additional sensor. Visit

information about changes in voltage offsets in the
NI 9237E.
