This is true. The precision is one degree, Farenheit or Celsius. The question however, was about accuracy.
Until someone (paging @Stu) tests it with a temperature probe, we can only judge the accuracy by the output as I descibed above. Even if it is tested, that would only represent a single device. You'd need to measure several to see how consistent they are. We already know that silver units are different from black ones, but how does that affect the heater temperature? Where is the temperature sensor located inside the V3 Pro? Is it measuring the heater or atempting to measure the load? How does the temperature change during a draw? How many degrees does it shift during a light draw as opposed to a strong one? For me, here's the important question: does it matter?
You can probably see where I'm going here. I don't think it matters at all.
All very true!
Even with a Fluke meter, choosing the proper temperature probe, where and how it’s mounted, makes a difference too.
I’ve studied many of these subjects in the past, and it’s understandable why “temperature”, is such a misunderstood component. That’s why your advice is perfect for most, that don’t want to go down that rabbit hole.
