int32 DAQmxAdjust1520Cal (uInt32 calHandle, float64 refVoltage, float64 measOutput);
Adjusts the external calibration constants for the SCXI-1520 module. You must supply a known voltage to the device and specify that voltage with refVoltage.
This device needs reference signals of 0.0 volts at gains of 1, 15, 20, and 310 on a particular channel in order to perform an offset calibration for that channel. If those points are not manually supplied, they will be automatically measured internally with sample and hold enabled.
