Adjusts the external calibration constants for a FD-11637 device. For full bridge configurations, gain and offset constants are adjusted. For all other bridge configurations, only offset constants are adjusted. This VI reports the as found error for gain and offset of the device.

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.

  • cdbl.png reference value —

    reference value specifies the reference value measured using a calibrator. The value to specify depends on the bridge mode you are using. For full bridge mode, this value is the ratio, in V/V, of the DMM readings of AI+ vs AI- and EX+ vs EX-. For half bridge mode, this value is the ratio, in V/V, of the DMM readings of AI+ vs EX- and EX+ vs EX-. For quarter bridge modes, this value is the measured value of the connected resistor, in ohms.

  • 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.

  • idbl.png actualReading —

    actualReading indicates the value the device read during calibration. This value is used to determine gain and offset errors.

  • idbl.png asFoundGainError —

    asFoundGainError indicates the calculated gain error.

  • idbl.png asFoundOffsetError —

    asFoundOffsetError indicates the calculated offset error.

  • 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.
