Tool/software:
Hello, I am currently a developer working on connecting an external load cell to the PGA305. After reading the PADC values, I plan to use a calibration process to convert them into kilograms. However, I noticed that as the temperature increases, the ADC values decrease, and as the temperature decreases, the ADC values increase.
After reading the TADC value and following the conversion process outlined in the datasheet, I compared it with a real thermometer. I found that the temperature values obtained through the datasheet's conversion method differ from the actual temperature by about 16 degrees overall.
1. Is it not possible to accurately determine the current temperature using the internal thermometer?
2. It seems like I need to use the TADC value for compensation in order to accurately measure the weight using the PADC value, but I'm not sure how to do that.
3. If the method I just mentioned is incorrect, could you please let me know how I can obtain consistent data without being affected by temperature?
