Load Cell Amplifier reading only 0.00

Hey guys,

I have a load cell amplifier that I am just now experiencing it reading values of exactly 0.00. I am not sure what is triggering it but this behavior doesn't seem repeatable. At times it will not and at times it will. Any ideas of why this happens?

Below is the original portion of the code that calls for it.

                while (temp_it < 5)
                { // Read 5 non-0 values as warmup
                  scale.get_units(value, 1);
                  Serial << "Value: " << value << endl;
                  if (value != 0)
                    temp_it++;
                }

I then modified it to use the is_ready check of the amplifier. Also after doing some google search, others were saying that it needs a delay. I then added a 500 ms delay.

                while (temp_it < 5)
                {
                  if (scale.is_ready())
                  {
                    scale.get_units(value, 1);
                    Serial << "Value: " << value << endl;
                    if (value != 0)
                    {
                      temp_it++;
                    }
                  }
                  else
                  {
                    delay(500);
                  }
                }

In both scenarios I still get 0.00 at times and this affects me because I am taking readings and averaging them. Therefore, I would end up averaging in some of the 0.00 values at times.

Show all your code in code tags after doing a Tools/Auto Format. Also include a photo of your hand drawn wiring diagram.

The ADS123x is not a load cell amplifier, it is an ADC.
Which one are you using, the two channel or four channel?
Which library are you using?
Which Arduino are you using?
