ADC CS5532: "digital gain scaling" - ADC Calibration without full scale signal
I'm making a digital weight scale with Arduino and CS5532.
My problem is to calibrate adc with the offset signal and a known weight signal that is not full scale point.
The CS5532 allows me to ...

Calibrating 500 kg load cell with an ESP32 and HX711 without putting actual 500 kg on it. 3 V excitation
Edit and update !
Considering the following data sheet ( calibration data from factory) what is the correct math to calculate the weight?
500 Kg = Excitation * rated output. ?
Or
Weight = 41.01 * ...
