DAQmxCreateAIDeviceTempChan

int32 DAQmxCreateAIDeviceTempChan (TaskHandle taskHandle, const char physicalChannel[], const char nameToAssignToChannel[], int32 units);

Purpose

Creates channel(s) that use a sensor built into a terminal block or device to measure temperature and adds the channel(s) to the task you specify with taskHandle. On SCXI modules, for example, this could be the CJC sensor.

Parameters

Input
Name Type Description
taskHandle TaskHandle The task to which to add the channels that this function creates.
physicalChannel const char [] The names of the physical channels to use to create virtual channels. You can specify a list or range of physical channels.
nameToAssignToChannel const char [] The name(s) to assign to the created virtual channel(s). If you do not specify a name, NI-DAQmx uses the physical channel name as the virtual channel name. If you specify your own names for nameToAssignToChannel, you must use the names when you refer to these channels in other NI-DAQmx functions.
If you create multiple virtual channels with one call to this function, you can specify a list of names separated by commas. If you provide fewer names than the number of virtual channels you create, NI-DAQmx automatically assigns names to the virtual channels.
units int32 The units to use to return the measurement.
Name Description
DAQmx_Val_DegC degrees Celsius
DAQmx_Val_DegF degrees Fahrenheit
DAQmx_Val_Kelvins kelvins
DAQmx_Val_DegR degrees Rankine

Return Value

Name Type Description
status int32 The error code returned by the function in the event of an error or warning. A value of 0 indicates success. A positive value indicates a warning. A negative value indicates an error.
