EC module spitting out incorrect data

I purchased the EC module and uploaded the code on the EC module wiki page to my arduino uno but I keep getting incorrect data such as shown below:
Analog value:402 Voltage:1962mV temp:0.00^C EC:Out of the range!
I've connected the EC sensor and the DS18b20 sensor to the I/O expansion shield v 7.1 so I know the connections aren't wrong. Do you have any suggestions as to what's wrong or is the product faulty?

Would you mind to introduce more details about the whole process when using the module? Did you make a calibration before test? Some photos for your diagram and the serial screenshots might be helpful for us to understand what happened.
Looking forward to your reply.
Have a good day.
