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.

minimumValue

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

maximumValue

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

voltageExcitationSource

Type: NationalInstruments.DAQmxAIExcitationSource
The source of excitation.

voltageExcitationValue

Type: SystemDouble
The amount of excitation in volts that the sensor requires. Refer to the sensor documentation to determine this value.

initialBridgeVoltage

Type: SystemDouble
The output voltage of the bridge in the unloaded condition. NI-DAQmx subtracts this value from any measurements before applying scaling equations. Perform a voltage measurement on the bridge with no strain applied to determine this value.

leadWireResistance

Type: SystemDouble
The amount of resistance in ohms in the lead wires. Ideally, this value is the same for all leads.

units

Type: NationalInstruments.DAQmxAIStrainUnits
The units to use to return the strain measurement.

Return Value

You must configure the physical channel(s) with TEDS information to use this method.

The NI-DAQmx driver does not determine if the requested settings are possible until the task is verified. This method 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.
