hi,
on the first time i'm sorry for my english... 
i have a big problem for acquire the temperature in my application (vb.net 2003).
So i'm novice i use NI's Example "ContAcqVoltageSamples_IntClkwGraph_Vb".
This example is ok for acquire the Volt but not the temperature.
I try to replace in this example the line "myTask.AIChannels.CreateVoltageChannel(physicalChannelTextBox.Text, "aiChannel", AITerminalConfiguration.Differential, -10, 10, AIVoltageUnits.Volts)" by "myTask.AIChannels.CreateBuiltInSensorTemperatureChannel(physicalChannelTextBox.Text, "AiChannel", AITemperatureUnits.DegreesC)" but in my graph on the MainForm i can see the volt and not the temperature.
I used the dev1/ai1 channel but if i want to use dev1/ai1 an error message explain "Built in temperature sensor is not supported on this channel".
I don't understand because when i use "Measurement & Automation" i can create "Tache Nidaqmx" for acquire my temperature on the channel dev1/ai1.
Please can you help me, it's urgent for my job and i'am a student.
Thanks
