IviDmm Extension Capability Groups
The IviDmm class driver identifies VIs and properties that belong to an extension group with the following abbreviations. Instrument specific drivers are not required to implement any of the extension capability groups. If you use VIs and properties that belong to extension capability groups, every instrument specific driver that you use must implement those extensions.
| Group Name | Description |
| IviDmmACMeasurement | Defines properties that configure additional settings for AC measurements. These properties are the minimum and maximum frequency components of the input signal. This extension group also defines VIs that configure these properties. |
| IviDmmAutoRangeValue | Supports DMMs with the capability to return the actual range value when auto ranging. |
| IviDmmAutoZero | Supports DMMs with the capability to take an auto zero reading. In general, the auto-zero capability of a DMM normalizes all measurements based on a Zero Reading. |
| IviDmmDeviceInfo | Defines a VI and a set of properties that you can query to gain additional information about the instrument's configuration |
| IviDmmFrequencyMeasurement | Supports DMMs that take frequency measurements. It defines properties that are required to configure additional parameters needed for frequency measurements. |
| IviDmmMultiPoint | Supports instruments capable of acquiring measurements based on multiple triggers, and acquiring multiple measurements for each trigger |
| IviDmmPowerLineFrequency | Supports DMMs with the capability to specify the powerline frequency. |
| IviDmmResistanceTemperature Device | Supports DMMs that take temperature measurements using a resistance temperature device (RTD) transducer type. |
| IviDmmSoftwareTrigger | Supports DMMs that can initiate a measurement based on a software trigger signal. You can send a software trigger to cause the DMM to initiate a measurement. |
| IviDmmTemperatureMeasurement | Supports DMMs that take temperature measurements with a thermocouple, an RTD, or a thermistor transducer type. This extension group selects the transducer type. Other capability groups further configure temperature settings based on the transducer type. |
| IviDmmThermistor | Supports DMMs that take temperature measurements using a thermistor transducer type. |
| IviDmmThermocouple | Supports DMMs that take temperature measurements using a thermocouple transducer type. |
| IviDmmTriggerSlope | Supports DMMs that can specify the polarity of the external trigger signal. It defines an property and a VI to configure this polarity. |
