Writes the specified binary value to the DAC on the specified physical channel at the specified range. Measure the voltage or current generated, then use the DAQmx Adjust SCXI Calibration VI to specify the measured value and adjust calibration constants.

Note Specify at least two calibration points for each physical channel and range you calibrate. Use 0 and 4095 for voltage calibration ranges. Use 255 and 4095 for current calibration ranges.

Inputs/Outputs

  • cu32.png calhandle in —

    calhandle in is a reference to the calibration session that you created using the DAQmx Initialize External Calibration VI.

  • cdaqmxscale.png physical channel —

    physical channel specifies the physical channel to calibrate.

  • ci32.png range —

    range specifies the range to calibrate.

    0Volts to 1Volts (14629)

    0 V to 1 V.
    0Volts to 5Volts (14630)

    0 V to 5 V.
    0Volts to 10Volts (14631)

  • cu32.png DAC value —

    DAC value is the binary number to write to the DAC.

  • cerrcodeclst.png error in —

    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.

  • iu32.png calhandle out —

    calhandle out is a reference to the calibration session. Wire this output to other external calibration VIs.

  • ierrcodeclst.png error out —

    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.
