Sencore Mighty Mite....Why are all tubes testing the same???

This is my 2nd tube tester I have purchased in the past month, and this one doesn't seem to be working either.
Does anyone know why every tube I test in this measures the same exact emission? The needle always falls in the same exact spot between ? and good.
I did notice a small capacitor, 50uf/50v, inside;
would changing that help?
