Close External Calibration (G Dataflow)

Last Modified: August 28, 2017

Ends an external calibration session that you began using Initialize External Calibration. You can choose whether or not to write the new calibration constants set by an external calibration function to the device's non-volatile onboard memory using action.

Note  
  • After invoking Close External Calibration, you cannot use the NI-Sync session handle again until you invoke Initialize (niSync) or Initialize External Calibration.
  • If you invoke this function with action set to Commit, the function updates the external calibration date stored in the device's non-volatile onboard memory, even if no calibration constants were changed.

instrument handle in

The instrument handle that you obtain from Initialize.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

action

A 32-bit integer that specifies whether or not to write the external calibration constants set using an external calibration function to the device's non-volatile onboard memory. Valid values:

Abort Discards any changes made with an external calibration function and maintains calibration constants at their original value.
Commit Writes any changes made with an external calibration function to the device's non-volatile onboard memory. These are the new default calibration constants for the device.

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
