USB-6341 and Temperature Measurement

Has anyone been able to measure temperature using thermocouples connected to the USB 6341?  I have been told the unit does not have CJC,  which is surprising to me.  From what i see, there exists significant thermal variation when measuring temp with ta 6341.  Has anyone come up with a method of using a thermocouple or RTD with a 6341 to measure temp?

Thanks,

Erik
