Filtering for a weighing system

[ozdemirmcihad]

I'm building a weighing system. Here I filter analog data with kalman filter and moving average. I have a problem like this.

I put 2 kg on the scale and shake the weighing mechanism and create vibration. In this case, the 2 kg value moves +- 20 grams. If I increase my filtering coefficients, this play disappears, but this time the system reacts very slowly to changes of 1 gram. How can I solve this problem can you help me.
