Temperature acquisition on NI USB-6259

[GabrielPereiraaa]

Thank you!! It helped a lot!

There's a fill things that didn't work out on my program. For example, at the beggining, I wasn't able to use an AI Voltage at my DaqMx, when I do, the program doesn't capture any temperature, so I'm using AI Temp TC.

Beyond this, I also wasn't able to see the temperature changing when I grab the wire. Now the temperature is almost constant, but doesn't change for nothing.

I'm sending my program for you to see how is it going.

Did you learn anything from NIquists "FIX" example? It seems not…

• Your USB6259 isn't made for TC measurement but you still use the "AI TC" mode.
• You still read a waveform from DAQmx even thoug you request only one sample per read.

Please follow NIquists example and apply the correct formula for your specific TC!

(It also would help to calculate the measurement uncertainty from all the USB6259 specs!)
