Hi Abhijit, The shorted input tests appear normal. There is a slight negative offset (not unusual) and the code variation is within expectations for peak to peak noise. When you connect the load cell you should get similar results. With no weight on the load cell the output should be near zero or in a balanced state (similar to the shorted case). If you repeat the same measurements you should get similar results. If they are much noisier, then noise is getting into the measurement path. Usually this is EMI/RFI and/or power line cycle noise. Any noise from nearby motors or where high switching currents are taking place can enter the cabling that acts as an antenna. Best regards, Bob B
