Labview 8.0 connected to a USB-6008
 
I am using 'BC Components' NTC Thermistor. I used the express VI to create a Vex input and entered the A,B,& C values from the datasheet. The thermistor is the 10K version and I placed a 10K resistor in series with it. I wired it as is shown in the connection diagram, and applied 2.5 volts to it.
 
I get completly the wrong temperature readings out of it! I called the NI help line in the UK and the engineer confirmed that I had done everything correctly but couldn't understand why it didn't work.
 
Any thoughts?

I had a similar problem, had it working at one point then screwed it up.
try this:


Temp Pressure EXpress.vi:

Thanks for the 'Temp Pressure EXpress80.vi' but it won't load because LV can't find the 'Convert thermistor reading.vi'. Either it is a VI that you wrote or it is part of LV8 that I haven't loaded.
I'll give it a try once I get it working.
 
 
I will also try the 4 wire mode before I send a device to NI.
