Thermistor reading show -273.15 Value in reading even after A, B, C Values based on datasheet.

Hello All,

I am trying to integrate my Thermistor with mu USB-6002 to read the temperature. As am also configuring A, B and C Values in NI Max still it shows -273.15 C as a temperature. Can anyone help me with the solution to get the exact temperature values in NI Max.

I am attaching my Circuit diagram here for reference. Do let me the know the solution.

Ensure that DAQ's AIGND is connected to the +5V ground powering the thermistor. Please share your code to ensure you have setup the DAQ correctly.

Hey Santhosh,

I've shorted DAQ's AI GND and 5V GND, but still i am not getting the correct reading.

Regarding the code, I am testing this in NI MAX environment by creating the task.

Do we have any other solution for this?

Check with a multimeter to ensure the voltage across the thermistor is proportional to temperature.
