DAQmx Adjust 4220 Calibration
Adjusts the internal and external calibration constants for an NI 4220 device. This device requires 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 you do not manually supply those reference signals, the device measures them internally with sample and hold circuitry enabled.

calhandle in is a reference to the calibration session that you created using the DAQmx Initialize External Calibration VI. | ||||||
 |
physical channels specifies the physical channel(s) to calibrate. | ||||||
 |
gain specifies the gain setting to calibrate. | ||||||
|
reference voltage specifies in volts the known voltage to use as a reference for calibration. | ||||||

error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. If an error occurs while this VI or function runs, the VI or function runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

calhandle out is a reference to the calibration session. Wire this output to other external calibration VIs. | ||||||
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
