DAQmx Adjust DSA AO Calibration
Adjusts the external calibration constants for the analog output section of a DSA device. You must use the device to generate a high voltage and low voltage at a specified gain, measure the high and low voltages, then specify the requested high voltage, low voltage, and gain along with the actual high voltage and low voltage.

Find on the Functions palette. |

calhandle in is a reference to the calibration session that you created using the DAQmx Initialize External Calibration VI. | ||||||
|
channel is the number of the channel to calibrate. This number is the numeric portion of the physical channel name, not the full physical channel name. | ||||||
 |
requested low voltage is the low voltage you attempted to generate at the gain setting you specified. | ||||||
|
actual low voltage is the actual low voltage an external sensor measures. | ||||||
 |
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.

actual high voltage is the actual high voltage an external sensor measures. | ||||||

gain setting is the gain setting you used when you attempted to generate the requested high voltage and requested low voltage. | ||||||

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.
