Potentiometric and µV measurements
The differential amplier of the DAQP-BRIDGE-B module is designed to measure small voltages (with very
low offset drift and high amplication). These are exactly the same requirements than for μV ampliers.
By setting the bridge input type to Voltage you can select input ranges from ±0.5 mV to ±500 mV. The
advantages of using bridge ampliers for μV measurements: only one multifunctional module with high
bandwidth, a lot of input and lter ranges and a programmable offset (Auto Zero).
The correct hook-up is simply connecting your µV signal to the IN+ and IN- pins of the this module, and be
sure to use a shielded cable and connect the drain to the ground pin of the DSUB connector on the DAQ
module.
