I am using PT100 (3 Wire) to measure the temperature. I have connected everything perfectly. Configuration in the code i am using is : max1.begin(MAX31865_3WIRE);

And the output is: output RTD value: 0 Ratio = 0.00000000 Resistance = 0.00000000 Temperature = -242.02

I am testing it in a room temperature. My question is , is there any settings or calibration that i need to do, or any other way to test the PT100 sensor, because the temperature is showing correct readings.
