Instrument Control (GPIB, Serial, VISA, IVI)

[Dinakar]

Hi, I am trying to read the temperature data from the keithley data logger but I am getting the wrong readings. The code is as follows. I got this program from a sample code provided by keithley. Can anyone explain tis code to me.

Dim reading As Double
        Dim isOverRange As Boolean


        Try
            Using vi As New KE2700("TemperatureReader", True, True)

                System.Console.Out.WriteLine("One-shot T/C Temperature Measurement, 2700 Manual, p. 2-49, example #3")

                ' There are two alternative implementations.

                ' Implementation 1: Uses vi.ChannelList to pass the channel name
                ' configure the temperature unit,  KE2700Properties.TEMPUNIT is not channel-based.
                vi.SetInt32(KE2700Properties.TempUnit, "", KE2700Constants.TempFahrenheit)

                ' configure function and range
                vi.SetChannelList("101")
                vi.ConfigureMeasurement(KE2700Constants.Temperature, KE2700Constants.AutoRangeOn, 0.0001)

                ' Configure the temperature transducer type as Thermocouple,
                vi.ConfigureTransducerType(KE2700Constants.Thermocouple)

                ' configure the thermocouple type and reference junction type
                vi.ConfigureThermocouple(KE2700Constants.TempTcJ, KE2700Constants.TcRefSimulated)

                ' set the simulated reference junction value
                vi.ConfigureSimRefJunction(32.0#)

                ' init and fetch a reading
                vi.Read(5000, reading)

Actually, what does this mean 
KE2700Constants.TcRefSimulated

vi.ConfigureSimRefJunction(32.0#) How is this 32.0 set.

Kindly explain this code.

Thank you.

That appears to be .NET

If you don't understand .NET perhaps some tutorials would be helpful.

Otherwise, talk to Keithley. It's their code.
