Hi Giuseppe,
From what you are describing, I believe that there is a calibration issue with the CEC software.? I would recommend you follow the method using the S.Meter Assistant button, reading the high and low values as described, then select the response curve to set the meter points.? It should be described on the web page that I sent you.
I had a similar problem calibrating the S Meter until I found the assistant and the automatic scaling function in the Memory Manager software.
