Owning Palette: Timing VIs and Functions

Requires: Base Development System

Waits the specified number of seconds with higher resolution than you can obtain with the Wait (ms) function. For example, use this VI in applications that require waiting with sub-millisecond resolution between steps. The resolution of the timer this VI uses varies with different operating systems and CPU types.

Unlike the Wait (ms) function, if the number of seconds you specify is 0, this VI does not force the current thread to yield control of the CPU. Use this VI with caution if you are concerned about high CPU loads: this VI may use polling to achieve high timing resolution for all or a portion of the wait time.

seconds to wait specifies the number of seconds to wait.

If seconds to wait is equal to or less than 0, the VI does not wait at all. If seconds to wait is 0, this VI also does not force the current thread to yield control of the CPU.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
error out contains error information. This output provides standard error out functionality.
