Remarkably handy and accurate!
I bought this LCR ESR meter primarily for measuring Equivalent Series Resistance (ESR) for capacitors, but it also tests resistors quite accurately (both types test very close to results on my Fluke and Brymen meters), as well as diodes/LEDs, transistors and induction/coils. Pretty amazing little device. It comes with no instructions but it's pretty simple to figure out: if the item being tested has two leads, insert in any two different numbered slots -- if three leads, use any three different numbered slots. It's that easy -- the device will figure out what it is and what the leads are. Only downside is that it will struggle with testing LEDs of 10w or more in that some it will 'understand' and others it will show as a bad device (even tho it's not). I suspect it may have problems with other high-current diodes as some have mentioned for similar devices but I have not tested any of those and the ones I did test it handled fine. The three supplied clip leads are very low quality but do work fine ...the extra crimp pins provided can be used to make higher quality leads if so inclined. Overall, a great little tester at an excellent price. Oh, it also charges very fast via it's USB (provided) cable. What's not to like?!
