Parameters
| Input | ||
| Name | Type | Description |
| Instrument_Handle | ViSession | Identifies a particular instrument session. You obtain the Instrument_Handle parameter from niDMM_init or niDMM_InitWithOptions. The default is None. |
| Maximum_Time | ViInt32 | Specifies the Maximum_Time allowed for this function to complete in milliseconds. If the function does not complete within this time interval, the function returns the NIDMM_ERROR_MAX_TIME_EXCEEDED error code. This may happen if an external trigger has not been received, or if the specified timeout is not long enough for the acquisition to complete. The valid range is 0–86400000. The default value is NIDMM_VAL_TIME_LIMIT_AUTO (-1). The DMM calculates the timeout automatically. |
