You seem to be getting a bit defensive now Steve, I hope I didn't touch a raw nerve, not the intention just passing an opinion which may be right or wrong. Selling test equipment and having a technical background are two different things, I never met a rep yet from any of the manufacturers who I would call technical , mainly sales BS from a script. Do you realise what you are saying, have you looked at the size and turnover of Megger and Fluke compared to HT Italia. They could buy them eat them for dinner and spit them out from their loose change.
I also think you need to do a little more research yourself regarding Megger and Fluke because you are way off the mark, as a senior technical director and more recently purchasing director I have had the pleasure of visiting the Megger facility in Dover and the Fluke facility in Norwich and while work may be duplicated in other countries they definitely manufacture and repair in both Dover and Norwich I have seen that with my own eyes. Maybe you should pay a visit. They are worldwide companies and are responsible for the design and manufacture of their own products irrespective of the country of manufacture. There is a difference between manufacturing product in a country and buying products from a third party manufacturer.
I am glad to hear that you have technical expertise within the company though even if you are not technical, if so you can get an answer to my original questions.
1. How does the meter measure volt drop
2. Explain the harmonics function and which type of engineers would use this and in which applications
3.The blurb mentions single phase and balanced 3 phase systems. How would the meter cope in an unbalanced 3 phase system?
