Title: How not to copy Chinese multimeters
Post by: Bored@Work on June 10, 2012, 05:20:32 pm
Lets say you want to sell a copy of a multimeter of one of your fellow Chinese manufacturers, then please, at least do an own photo of your copy, and don't use

to advertise your UA9205N multimeter.

At least you are an equal opportunity copier, 8269 multimeter

At some point you got a little bit more bold and use your own photo

(can someone figure out with what they replaced the Uni-T label?)

But well, you shouldn't get so confused as to mix a Uni-T with a Victor multimeter

But really, what is the point in cloning Uni-T, Mastech, and by all means Victor?  :o

Really, can we be entirely sure which one is the copy and which one the clone?

None of this stuff seems to even resemble top or even middle tier equipment.  It kinda' looks like your typical example of Chinese industrial cannibalism.

I was almost expecting a flipped or mirrored silk screen :)

A quick teardown.. crappy pictures but .. gives a impression on whats inside..

I like how the transistor above R6 and PTC1 need to be folded over presumably due to the height of the components so the case can fit on? Both are so close to the side casing.

I have 2 of those meters from circuit specialist USA.  They look exactly like Erik's pictures. When you need a third and fourth meter for low voltage circuit stuff they work extremely well.  Every function that I have cheked against my 87-5 has been very accurate. I intentionaly buy some stuff from them to get extra free meters.

They are always available free for orders over $50 but it is not obvious.  After you have >$50 of items in your cart click on the "free gift with purchase, click here for details" at the header and you will then be able to add the meter (or other items) to your cart for free.

It seems a good multimeter to use has a panel meter on a power supply... ;D ;D

I just checked one of mine against my calibrated 8846A and on volts from 100mV to 20V it is less than 0.05% error. :o
