    Last Modified: March 3, 2017

    Configures instrument coupling for voltage waveforms.

    connector_pane_image
    datatype_icon

    session in

    Instrument identifier from previous NI-DMM nodes.

    Default: None

    datatype_icon

    coupling

    Setting for DC or AC coupling.

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

    Value Description
    0 AC coupling
    1 DC coupling

    Default: 1 (DC coupling)

    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.
