Hi,

When calibrating the 502, I can follow all the steps, but when indicated to turn the gain up to get exactly 15V AC, i can only reach 11.4V

The rest of the setup I can follow no problem, and the module works ok.

Should i be concerned? Anywhere where I could check?

Thanks

In step 5 what is the maximum voltage you can get?
Can you reach 15V if you increase the input signal?
Do you confirm that your input is actually 1VAC?
