Hi,
Which version of LabVIEW are you using and which DAQ board? If
you are using LabVIEW 7.0 or higher and a DAQ board that supports DAQmx
(
NI-DAQ Driver Support),
then you can actually make a temperature measurement directly.
There are many examples that show exactly how to do what you want if
you look in the Example Finder:
Help > Find Examples > Browse > Hardware Input and Output > DAQmx > Analog Measurements > Temperature
Look at
Acq Thermocouple Sample.vi or
Cont Acq Thermocouple Samples-Int Clk.vi.
If you have an older version of LabVIEW or you just want to simply use your application and then find the VI called
Convert Thermocouple Reading.vi (the one Henrik suggested.)
Regards,
