Hello i am using NAU-7802 24-bit adc.I want to stabilize the digital ouptput.I have already done filterng ,averaging,Not getting constant output.
I want to measure the exact grams (not kilograms)from the load cell.Because of fluctuating ADC output i cannot measure the exact weight.
Please send the circuit diagram if anybody has already used NAU-7802 24bit ADC. and calculation for mapping.

 

Variations in load cell output need to be identified first.

Is there a corresponding variation in the supply voltage? Is there physical movement of the load from wind or vibration? Is there a voltage reference source? What kind, and how free of variation is the reference signal?

 

No sir,
The input is constant 3.3v and there is no any wind or vibration and i have set the gain to 128 for more accuracy.
I want to measure the weight in grams and as per my calculation,it is giving +5grams and -5grams fluctuations in weight
at no load (OFFSET).It is happening because of fluctuations at adc output.
