When using TEDS load cells it would be useful to have a built in tare function The null offset function only offsets the electrical value by the intialy measured amount. This essentially shifts the calibration curve horizontally only. The tare function could also shift the calibration curve vertically, in the load direction. Since two point calibrations don't always create a line that goes through zero, a tare function is needed to get to zero. Please see the attached VIs. Also, check out my thread on this subject.
