Hi Simon,
I personally have no experience or have seen outright fake Fluke DMM; but the Flikr post has tear downs of the DMM, so you may be able to compare the guts when you get it. If they look identical, test it thoroughly to insure it lives up to its spec sheet. You'd have to make an educated guess to know whether it has any safety rating that you'd be able to risk or live with.
Its common to outsource design and manufacture to many factories in China, with little regulation.
Just as example, if a model or brand name is popular, dishonest folks can make excess numbers of a product beyond the original client order or take quality control rejects, then sell these excesses without the client knowing. So, for most purposes, these can be identical to the real thing just not authorized by the client. These are the worse case types of counterfeit because they are essentially identical; the only way to know is the serial numbers are not authorized; the only pitfall of these products is that they don't get any quality control or inspection that is typical of Fluke or any client's procedures.
will let you know. If they are "copies" any way of telling ?
While we are on the subject of scammy meters please nobody buy a VC99, they are dreadful. Mine is temperamental to say the least and I cannot rely on the ohms function. If you must spend £30 on a meter get the AM220
