IviDmm Is Over-Range (G Dataflow)

Version:
    Last Modified: October 24, 2017

    Takes a measurement value that you obtain from either the Read or Fetch nodes and determines if the value is a valid measurement value or a value indicating that an over-range condition occurred. Notes: (1) If an over-range condition occurs, the measurement value contains an IEEE defined NaN (Not a Number) value indicating that an over-range condition occurred. (2) This node does not check the instrument status.

    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

    instrument handle

    The instrument handle that you obtain from the IviDmm Initialize Node. The handle identifies a particular instrument session.

    Default: None

    measurement value

    Pass the measurement value that you obtain from either the Read or Fetch VIs. The driver tests this value to determine if the value is a valid measurement value or a value indicating that an over-range condition occurred. Default Value: 0.0 Notes: (1) If an over-range condition occurs, the measurement value contains an IEEE defined NaN (Not a Number) value indicating that an over-range occurred.

    instrument handle out

    The instrument handle that you obtain from the IviDmm Initialize Node. The handle identifies a particular instrument session.

    Default: None

    error out

    Error information.

    The node produces this output according to standard error behavior.

    is over-range

    Returns whether the measured value is a valid measurement or a value indicating that an over-range condition occurred. Return Values: True - The value indicates an over-range condition occurred. False - The value is a valid measurement. Notes: (1) If an over-range condition occurs, the measurement value contains an IEEE defined NaN (Not a Number) value indicating that an over-range occurred.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

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