wrong readings

[ajinkyaw]

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.
