Parameters

| 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. |
| Channel_Name | ViConstString | This parameter is ignored. National Instruments DMMs do not support channel names since they only have a single channel. This parameter is included in order to support interchangeability and upgradability to multiple channel DMMs.
The default value is " " (an empty string). |
| Attribute_ID | ViAttr | Pass the ID of an attribute. |
| Attribute_Value | ViReal64 | Pass the value that you want to set the attribute to. |
