This smart SMD tester is essentially a pair of multimeter tweezers. This allows you to troubleshoot circuits with small SMD parts without having to fumble with large probes or long wires. Test resistors, capacitors and diodes one-handed!
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

It is handy, light and quite accurate. I keep it with me all the time. I simply fell in love with it.

Wow, fairly cheap too!
These work quite well, except for two issues: - the probes are about 1.2mm thick at the tip, which makes testing 0603 parts a bit clumsy. They can be easily unscrewed if you want to file them down, but this may affect the accuracy (there doesn't appear to be a way to calibrate it) - the lower bounds on the ranges (300Ω, 3 nF) are somewhat limiting. Caps in the pF range are often used with crystals, and having them measure in the nFs is quite confusing. This is definitely a case of PEBKAC, but having the minimum ranges printed on the case would make things a bit easier.
Conclusion: they do exactly what the spec says, but you're probably better off just getting some tweezer probes for a good multimeter.
30000µF? Is it right? I guess it's too much for such a cheap device...most multimeters, that are more expensive than this little tweezers, are able to measure just within 200µF. = ]
Some of you guys are looking for inductance meters.
Here is one trusted in the ham radio community. http://www.aade.com/lcmeter.htm $100 kit or $130 assembled. But not smd specific.
Been using these and love them. The Auto mode is very handy when measuring resistors and capacitors because it with toggle between them automatically (as well as diode testing but I hardly use that portion.) The documentation is a little fuzzy, but these power off automatically after 10-15 minutes of use, unsure if that resets from taking a measurement. Hold FUNC while they're on to turn them off manually. A sliding switch would have been useful here!
They don't have amazing resolution or range for tiny cap values, but if it can grab a rough/close value I prefer these to a +$100 LCR meter I use at work, think DMM with annoying tweezer wires. If only they could read inductance also!
(Clap clap clap) now one that will not break the bank.
with large probes are long wires.?
Also, they are missing a comma at "Test resistors, capacitors and diodes one-handed!" between 'capacitors' and 'and'.
That's sometimes called the "Oxford Comma". It's not required. Personally, I think it looks better aesthetically to include one but maybe Sparkfun doesn't.
It reads more smoothly without the comma, in my opinion. And, of course, MY opinion is BEST. (I'm being sarcastic)
Hello 10x cheaper!
How about a set of meter cables that has tweezers for probes, so we can use them with our normal meter?
make 'em yourself for about $0
Check eBay for that until Sparkfun start carrying it. You can get one for less than $10 dollars.
Too bad it doesn't measure inductance. I guess if it did, it would not cost $28.
VERY true. Inductance meters are hard to come by cheaply.
Thank you for the reply. Can you guys get one that does inductance? Even for twice the price of this, it would be worth it.
Here's a cool project It uses an arduino and an op-amp to measure inductance.
We can look around, but it might be more than twice the price.
I'll see what we can find.
The naming sounds like a rip off of Advanced Device's 'smart tweezers'.
I'm sure they're not the first company to call their product 'smart'.
True, but this product is very similar in function and design to the more popular (and overly priced) smart tweezers.
Companies will do that so you'll make that distinction without any legal implications.
Arduino: Seeeduino, Freeduino. Pretty sure Seeeduino didn't invent the Arduino template, but now I can remember Seeeduino makes Arduino-like stuff!
These probably are a "Smart Tweezers" knockoff. :)
