PGA305EVM-034: P GAIN CALCULATION

Part Number: PGA305EVM-034

 I'm having another problem related to P gain calculation. No matter what P1-min and P2-max values are,  the calculated gain is always equal to 5 (if the file is the P_Gain_Script_Template) or to 36.00 (if the file is the P_Gain_Script_Sample). I even tried to use the values in the image but the gain remains the same (5 or 36), not 5.48 as supposed.

    Hello Ana,

    The script file that is in this version of the GUI is not working properly. There currently isn't a newer version with a functioning gain calculation script. This something that will be updated in the future.

    For now the simplest way to determine the gain is to set your input to the maximum value and use trial and error adjusting the gain and reading the PADC value until the PADC readings are equal to the full scale of the ADC minus some margin for error (this will be determined by you).

    Regards,
