TriX and Ektachrome with Eumig Sound 30XL

[grainy]

Hi folks - a friend gave me his mint condition camera the other day and while the Eumig Sound 30Xl looks like a winner in some ways (f1.8 lens, sturdy build) it's entirely automatic exposure except for a +1 feature.
How can I tell if this camera will expose TriX and Ektachrome reversal properly? I should probably know this by now but I am numbers-impaired.
And - does anyone have experience with this model?
thanks!
