I am using National Instrument hardware (pci-6034e & CB-68LP) and labview 5.1 software for recording of temperature. After setup with these equipment i notice that the temperature wasn't too precise. In still water at constant temperature i get a range of 1.5 deg Celsius. Example: in water, ~25 deg Celsius (according the average of thermocouple readings), i get a thermocouple reading, through labview, of a minimum of ~24.5 and maximum of ~26.5.
I've tried a AD595 for the thermocouple and recorded the output voltage. I get the same result.
How would lessen these fluctuations?
