Configure Current Source (G Dataflow)

Last Modified: April 2, 2018

Configures the current source for diode measurements.

connector_pane_image
datatype_icon

session in

Instrument identifier from previous NI-DMM nodes.

Default: None

datatype_icon

current source

Amount of current provided during diode measurements.

NI-DMM sets the Current Source property to this value.

Default: 0.001 (1 mA)

datatype_icon

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

session out

Instrument identifier for subsequent NI-DMM nodes.

datatype_icon

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:

Valid values for the current source parameter vary among DMMs. The following table describes the valid values for each supported DMM.
