Temperature measurement(Thermocouple,-k-type) using Keithley 2000 DMM and 2001 scan card with GPIB interface

[syamni]

Sir,

I am a beginner in Labview and Urgently  I need a labview program for keithley 2001 scan card for thermocouple temperature measurement with GPIB interface and keithley 2000 DMM..

Any body please help me...

Thanks in advance

Did you do the simple task of going to Help>Find Instrument Drivers? Once you log in, specify Keithley and 2000, then download the driver. There will be an example (Help>Find Examples). The main instrument driver network has links on how to use a driver.

thank you sir ..

I have got  driver for keithley 2000  from NI Web ,but the program doesn't show reading in  temperature unit.Instead of temperature, it  is  showing voltage reading only. can you help me to convert multi channel thermocouple voltage to curresponding temperature..

Please refer my attachment..

Hi

Open the keithley 2000 project and in the lvlib under public you find the tree.vi.

Inside is a configuration vi for themocouple measurements

extend the case in the read single example so this one is used (also extend the selection) and see what happens.

thank you for your answer...but still  there is a problem to read temperature of all channels simultaneously in temperature unit..

can u help...

is there any polynomial equation for thermocouple  voltage to temperature conversion???

please help me...

Th keithley can do the caculation but in LabVIEW DAQMX library there are calculations for you.

The easiest way is to configure all channels and let the keithley do the caculations. I don't know by heart how but each channel should be treated with a configure.

can i use DAQmx for Keithley 2000 and 2001 scan card  with GPIB Interface???

[Albert.Geven]

No, you can't use daqmx to communicate, but you can read voltages and calculate the temperature by a daqmx function.
