niDMM Initiate
Initiates an acquisition. After you call this VI, the DMM leaves the Idle state and enters the Wait-For-Trigger state. If trigger is set to Immediate mode, the DMM begins acquiring measurement data.
Use niDMM Fetch, niDMM Fetch Multi Point, or niDMM Fetch Waveform to retrieve the measurement data.

instrument handle identifies a particular instrument session. You obtain the instrument handle parameter from niDMM Initialize or niDMM Initialize With Options. The default is None. |

error in (no error) describes error conditions that occur before this VI runs. If an error occurred before this VI runs, the VI passes the error in value to error out. This VI runs normally only if no error occurs before this VI runs. If an error occurs while this VI runs, it continues and sets its own error status in error out. Use niDMM Error Message to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

instrument handle out returns a handle that you use to identify the instrument in all subsequent instrument driver VI calls. |

 |
error out contains error information. If error in indicates that an error occurred before this VI ran, error out contains the same error information. Otherwise, it describes the error status that this VI produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
