Self-Test (G Dataflow)

Version:
Last Modified: September 16, 2017

Performs a self test on the DMM to ensure that it is functioning properly.

This node does not calibrate the DMM. This node calls Reset, and any configurations previous to the call will be lost. All properties will be set to their default values after this node runs.

If self-test fails, self-test message returns NIDMM_ERROR_SELF_TEST_FAILURE. This message indicates that the DMM should be repaired.

connector_pane_image
datatype_icon

session in

Instrument identifier from previous NI-DMM nodes.

Default: None

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

self-test result

Value returned from the instrument self test. A zero value indicates success.

datatype_icon

self-test message

String returned from the instrument self-test.

If you specify a string length for this parameter, it must be at least 256 elements long.

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:

For the PXI/PCI-4070, PXI-4072, PXIe-4080, and PXIe-4082, error code 1013 in self test result indicates that you should check the fuse and replace it if necessary.

For the PXI/PCI/PCIe/USB-4065, PXI-4071, and PXIe-4081, self-test does not check the fuse. For these DMMs, self-test does not return error code 1013 even if the fuse is blown.
