I am considering purchasing a U3-HV to connect a J-type thermocouple to a computer.  I am running Mac OSX with LabVIEW.  On some of my units, we run 2011 and 2012 on others.  I have been searching high and low for a USB device to accomplish this task.  My current theory is that if I download and install LabJackPython, Exodriver, and MacFUSE that I will be able to read data from my thermocouple using LabVIEW.  Again, this is LabVIEW for Mac.  Am I correct in this assumption?  If so, will I need to install a LJTick-InAmp?  Thanks for any help.

We recommend looking at the T7 first. It does not require an amplifier with thermocouples and we provide LabVIEW TCP examples which are operating system independent.


As for the U3-HV or LV, it will need an amplifier like the LJTick-InAmp. Refer to the thermocouples AppNote and LJTick-InAmp thermocouple documentation for details:





Regarding LJFuse and a U3 on a Mac (requires LabJackPython, Exodriver, and MacFUSE), that is a valid option. You can read the internal temperature sensor (cold junction temperature) and an analog input (thermocouple) through this interface. On the LabVIEW side, you will use file I/O operations for U3 communications.


For using LabVIEW and the Exodriver directly, refer to the LabVIEW examples here:
