T4P:
Forget about writing instructions, they can't even get datasheets done properly ... damn china
I'm still impressed by Cyrustek's datasheets even being Taiwanese ...

GEuser:
The kit thing saturation is exactly how i was explaining them on another place to someone a few weeks back too , but i used the scenario that the kit had be assembled by someone like ME and a purchaser then brought it and had to clean it up a tad .

nukie:
Most Chinese chips are copies of the western products that's why you dont see datasheet. Often I find chips that has same pinout, same packaging, look into thr datasheet 100% exact copy. How they perform in real world I am not so sure.

Well, yes. The exceptions to 240VAC 50Hz consist of: The USA, Canada, Japan, and various South American countries. The entire planet uses 240V 50Hz with the exception of those under the thumb of the US.

Including Hong Kong, the source of most of these devices, who also share the same plug as the UK.

I have one of these Atten 858D on it's way from Hong Kong. I was planning on a teardown to check for issues, even whithout knowing of this topic. Now that I read it it's definitely getting a thorough inspection.

Nicest surprise from the chinese QC was a extension cord that had "one of the other wires"  :-DD  and ground swithed over. Since I live in Europe, our plugs don't care for polarity. First time I plugged it in it worked fine because the neutral went to ground and vice-versa, which it did anyway in the panel board(no RCD). Second time I plugged it the other way around and got hot on the chassis ground.  |O As a bonus the equipment that's plugged in was not working, so it begged for me to touch it.  :-/O

I then realized there's a problem, opened the extension cord and checked for continuity, since the colors were right (yellow/green to ground) and found out that they were switched over insinde the moulded plug. It wasn't my cord to throw away, so I text labeled them and soldered them the correct way.
