You need to get to know your meter. And (!) how you interpret what it says to you.
Both require getting familiar with idiosyncrasies, the meter's and your own, and is not helped by comparing the meter to other meters.
If you have to go through all that, why use a meter at all? Why not expend that effort to learn the idiosyncrasies of your meter and how you need to interpret its reading into just learning to do without a meter? That's basically my philosophy. I can never be sure a meter is accurate, and most of the time the reading it gives me needs to be corrected anyway because of my own exposure judgments. So the utility of the meter is only in judging the actual brightness of the light, and I find that that can be judged fairly accurately with experience.
