I was hoping to finish up my testing this weekend for the new meter but ran into a minor setback. Parts are on order and should make it in next week.
It died much too early?
Two years of testing has taught me that the performance is not always proportional to the hype.
To date, I have documented 59 meters. This does not include a few like the Fluke 189. In the first set of tests, the AMPROBE AM510 was damaged at 5.8KV which is basically what I call my cutoff point. Make it above that level, you have a decent meter IMO. We have 15 that meet that criteria or 25%. If we include the Fluke 189 and assue that one 87V that I had repaired and reseted to be a flyer, then we have 17 out of 60 or 28.3%. Of course, I have been running what I consider a better class of meter lately which biases the data.
Of these, the brands that stand out are and Fluke and Brymen. While the Gossen and HIOKI both did very well, I only looked at one product from these companies. I have said that I use a HIOKI product for work and personally, that carries some clout after what I have put it through (transient wise). We are not talking about these little piss ant transients I apply to benchmark these meters.
Statistically speaking, I would say the meter I am looking at now ...... (you don't want me to spoil it for you, do you? lol) Maybe we will have a new brand join the Flukes, Brymen's, HIOKI's and Gossens of the world. It's big shoes to fill and requires you know how to design.... Maybe....
