Configure ADC Calibration (G Dataflow)

Version:
Last Modified: September 16, 2017

Configures a DMM to compensate for gain drift since the last self-calibration or external calibration.

When ADC calibration is on, the DMM measures an internal reference to calculate the correct gain for the measurement.

ADC Calibration

Setting for ADC calibration.

NI-DMM sets the ADC Calibration property to this value. The following table describes the valid values for this parameter.

Value Setting Description
-1 On Enables ADC calibration. The DMM measures an internal reference to calculate the correct gain for the measurement.
0 Off Disables ADC calibration. The DMM does not compensate for changes to the gain.
1 Auto The DMM enables or disables ADC calibration based on the configured function and resolution.

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

session out

Instrument identifier for subsequent NI-DMM nodes.

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

Hardware Support:

The following DMMs support this node:

  • PXI/PCI-4070
  • PXI-4071
  • PXI-4072
  • PXIe-4080
  • PXIe-4081
  • PXIe-4082

Additionally, these DMMs have the following default behavior:

  • For 6.5 digit and greater resolution DC measurements, NI-DMM enables ADC calibration.
  • For all other measurement configurations, NI-DMM disables ADC calibration.
