Takes one or more voltage measurements from the onboard calibration ADC and returns their average value. The signal that the ADC actually measures can be specified using the Cal ADC Input property. The ADC has some inherent gain and offset. These values can be determined during an external calibration session and stored in the calibration EEPROM.

If the Return Calibrated Value? is TRUE, NI-FGEN adjusts the value that is returned to account for the gain and offset of the ADC. Otherwise, the raw voltage value reported by the ADC is returned.

Inputs/Outputs

  • civrn.png Instrument Handle —

    Instrument Handle identifies a particular instrument session.

  • ci32.png Number of Reads to Average —

    Number of Reads to Average specifies the number of measurements to be taken and averaged to determine the return value.

  • cbool.png Return Calibrated Value? —

    Return Calibrated Value? specifies whether the voltage returned from the ADC should be adjusted to account for the gain and offset of the ADC.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

    Default value: no error

  • iivrn.png Instrument Handle Out —

    Instrument Handle Out passes a reference to your instrument session to the next VI.

  • idbl.png Calibration ADC Value —

    Calibration ADC Value returns the average of the voltage measurements taken from the onboard calibration ADC.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
