Self-calibrates most NI digitizers, including all SMC-based devices.

For SMC-based devices, if the self-calibration is performed successfully in a regular session, the calibration constants are immediately stored in the self-calibration area of the EEPROM. If the self-calibration is performed in an external calibration session, the calibration constants take effect immediately for the duration of the session. However, they are not stored in the EEPROM until you call niScope Cal End with action set to Store Calibration and no errors occur.

Note To verify that your digitizer supports self-calibration, refer to Features Supported by Device.

Inputs/Outputs

  • civrn.png instrument handle —

    instrument handle identifies a particular instrument session.

  • cstr.png channels —

    channels specifies the channel(s) to calibrate. For more information, refer to Channel String Syntax.

  • ci32.png Option —

    Option allows you to self-calibrate all channels or restore the external calibration.

    Defined Values

    Self-Calibrate All Channels (Default)

    Restore External Calibration

  • cerrcodeclst.png error in —

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

  • iivrn.png instrument handle out —

    instrument handle out has the same value as the instrument handle.

  • ierrcodeclst.png error out —

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