Parameters

physicalChannelName

Type: SystemString
The names of one or more physical channels to use to create one or more local virtual channels.

nameToAssignChannel

Type: SystemString
One or more names to assign to the created local virtual channels. To use the physical channel name as the local virtual channel name, set this value to Empty.

configuration

Type: NationalInstruments.DAQmxAITerminalConfiguration
The input terminal configuration. To use the default terminal configuration for the physical channel(s) being used, pass a value of -1 casted to an AITerminalConfiguration.

minimumValue

Type: SystemDouble
The minimum value expected from the measurement, in units.

maximumValue

Type: SystemDouble
The maximum value expected from the measurement, in units.

sensitivity

Type: SystemDouble
The sensitivity of the sensor. This value is in the units you specify with sensitivityUnits. Refer to sensor documentation to determine this value.

sensitivityUnits

Type: NationalInstruments.DAQmxAIAccelerometerSensitivityUnits
The units of sensitivity.

currentExcitationSource

Type: NationalInstruments.DAQmxAIExcitationSource
The source of excitation.

currentExcitationValue

Type: SystemDouble
The amount of excitation in amps that the sensor requires.

customScaleName

Type: SystemString
The name of the custom scale to apply to the local virtual channel.

Return Value

This method creates a local virtual channel for every physical channel name you specify. If you create multiple local virtual channels with one call to this method, you can specify a comma-delimited list of names for nameToAssignChannel. If you provide fewer local virtual channel names in nameToAssignChannel than you create, NI-DAQmx automatically assigns names to the local virtual channels.

If you do not provide a value for nameToAssignChannel, NI-DAQmx uses the physicalChannelName as the local virtual channel name. If you use nameToAssignChannel to create a name for the local virtual channel, you must use this name in other properties and methods.

The NI-DAQmx driver does not determine if the requested settings are possible until the task is verified. CreateAccelerometerChannel(String, String, AITerminalConfiguration, Double, Double, Double, AIAccelerometerSensitivityUnits, AIExcitationSource, Double, String) does not throw an exception for parameter values that are not compatible with your hardware or other settings in your task. To determine if all of the settings for a Task are valid, you must verify the task by starting the task, either with Start or by reading from or writing to the task, or by calling Control(TaskAction) with Verify.
