AIChannelCollectionCreateTedsThermistorVExChannel Method
Creates an AIChannel that uses a thermistor to measure temperature. Use this method when the thermistor uses voltage excitation. This method adds one or more physical channels to the AIChannelCollection.
Namespace: NationalInstruments.DAQmx
Assembly: NationalInstruments.DAQmx (in NationalInstruments.DAQmx.dll) Version: 20.7.40.49302
Syntax
public AIChannel CreateTedsThermistorVExChannel( string physicalChannelName, string nameToAssignChannel, double minimumValue, double maximumValue, AITemperatureUnits units, AIResistanceConfiguration resistanceConfiguration, AIExcitationSource voltageExcitationSource, double voltageExcitationValue, double r1 )
Public Function CreateTedsThermistorVExChannel ( physicalChannelName As String, nameToAssignChannel As String, minimumValue As Double, maximumValue As Double, units As AITemperatureUnits, resistanceConfiguration As AIResistanceConfiguration, voltageExcitationSource As AIExcitationSource, voltageExcitationValue As Double, r1 As Double ) As AIChannel
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. - units
- Type: NationalInstruments.DAQmxAITemperatureUnits
The units to use to return the temperature measurement. - resistanceConfiguration
- Type: NationalInstruments.DAQmxAIResistanceConfiguration
The number of wires to use for resistive measurements. - 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. - r1
- Type: SystemDouble
The value of the reference resistor, in ohms.
Return Value
Type: AIChannelThe newly created AIChannel.
Exceptions
| Exception | Condition |
|---|---|
| DaqException | The NI-DAQmx driver returned an error. |
Remarks
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.
