OMRON PLC and Load Cell

Hi every one
I'm using OMRON CQM1H PLC to read weight from load cell indicator -locally manufactured-.
The problem is that the indicator gives me unstable signals and random vibrations
I tried to make averaging and this made things better but still have random vibrations and my manager insist on using this indicator.
I want to know if there is any algorithm (Like PID) or any control techniques that could help me?
Also if any one have experience with load cells can tell me the procedure used when reading signals from load cells?

We really need more information to be able to help.

What module is the load cell connected to?

Which CPU are you using?

Once we have this information, there may be more questions.

I'm using OMRON CQM1H CPU51 and analog module AD041
The load cell is connected to weighing indicator which outputs analog signal -10 to 10 volt to the PLC.

The attached is from the W238 manual CQM1 Special IO Units.

Thanks gtsuport
I tried the mean value processing function in addition to averaging function in the LD but still have random vibratiions.
I sorry if the problem is confusing but I was asking for a special algorithm used when dealing with a load cell?
