sxizas Posted July 6, 2011 Report Posted July 6, 2011 Hi, I' m using SCXI - 1121 with SCXI -1321 and the PCI - 60034E, I' m trying to take measurements with a thermistor (Iex) and I have a problem at the MAX. When I run the measurement it gives an error -200077 occurred at DAQ Assistant. I give you a snapshot of the problem! Thanks. Quote
Cat Posted July 7, 2011 Report Posted July 7, 2011 It's telling you your max value (100) isn't valid. Does it work if you set your max value between 198 and 300? Quote
crelf Posted July 7, 2011 Report Posted July 7, 2011 This could be because you're applying scaling that puts your 100 outside the curve. Quote
sxizas Posted July 8, 2011 Author Report Posted July 8, 2011 thanx for your help! When I change the max and min values, it's working and it gives a stable temperature of -273.15! I believe that the problem may be at thermistor's coefficients or at the calibration of the DAQ device (SCXI-1121), I'm right? Any other idea? Quote

Well, -273.15 is a suspicious number. 0 Kelvin = −273.15 °C [°C] = [K] − 273.15 Quote
