NI USB-6210

[FFoglia]

Hi! I am new with Labview!

I study the heating by Joule effect and I want to create a Labview program able to acquire simultaneously the temperature of the sample by thermocouples, the resistance of the sample by two wire method and the voltage. The voltage is applied by an external generator. 

I am also dubious about the circuit. 

Thank you for the help!

Unfortunately, USB-6210 is not accurate enough to measure Thermocouples (thermocouples generate in the order of microvolts per deg C).

Simplest Thermocouple DAQ - https://www.ni.com/en-us/support/model.usb-tc01.html

Maximum sampling rate 4 samples per second

A better option is to use cDAQ chassis with a c-series temperature input card such as this bundle,

Please note that the temperature measurements are typically slow in the order of tens of measurement per second.
