NI-DAQmx provides three methods to scale electrical values (voltage ratios) from a bridge-based sensor to physical units:
Datasheets or calibration certificates from sensor manufacturers often include a table of electrical and physical values or a polynomial equation for scaling. If you do not have a table or polynomial equation for your sensor, use two-point linear scaling. Use the rated output of the sensor and the sensor capacity as one pair of electrical and physical values. Use zero for the other pair of electrical and physical values.
