| Sorry
I don't mean to say that at all. Plasma meters are supposed to be more accurate. It is simply that they will on a lot of occasions have different readings with a large range of difference. Not inaccurate just not always consistent. That is why I check my test again if I get a high reading. To do a comparison. If they are both high then I believe them. If they read one high and one low I do a third and trust the 2 most closely together.
