How do I use the autotune function in Masslynx?

01 January 2015 0 6K Report

I saw there is a function - autotune in the tune page of the masslynx. but when I try to use it for my chemicals, every time I got a message says 'no ion beam found'.

But I did saw the ion beam at the tune page.

anything I need to do before use it?

In addition, is this used for precucier ion tune or daughter ions?

thanks.
