I am working with the U1733C since years, and I am very happy with it. No flaws, no errors. I love the Q-factor test function.

Very good review Dave, as always. :) I just love the amount of analog circuitry in there. LCR meters are a beautiful combination of some digital electronics and a whole bunch of analog stuff.

I ended up getting the 879B. I usually use it at 1khz, I dunno why. It always seems to get the job done. Just yesterday I fixed an HAI touchscreen with it. Two caps were part of it's switching regulator. One was 45ohm at 1khz and the other was 24ohm. If they're good, they usually read around .1 or .2 ohm. I still haven't discovered what capabilities I don't have since the 879b doesn't do over 10khz. Seems to work fine the way I use it.

@pulsecloud I could, interesting idea, but that requires a fair bit of work and takes a lot of time. I'm not really fussed about how much margin manufacturers are making on their devices. Only if the sell price is competitive and good bang-per-buck.

1) Test clip support - are the clips not supported by the rear case? 2) Protection - I suspect those blobby things are MOVs not polyfuses.

The characteristics of real components will vary with frequency. It therefore makes sense to measure a component using an excitation frequency near the actual frequency in use. As it turns out, most reactive components are used in switching circuits that run about 100 kHz.

Hey Dave! Do you ever plan on doing a final review of the Agilent U1272A? Thanks for the tear down, this new LCR meter looks pretty good!

I got my U1733C this week but i found two confusing bugs. the Tol% and the Rec mode didn't work as described. In the tolerance mode it did'nt beep and in recording mode only the first stable value will be used

@EEVblog The point isn't really to know how much margin the manufacturers make so we can call them names, but to have at least a non-null idea of what margin I could/should make when/if I made something to sell. For instance, if I had made the uCurrent you made I just wouldn't have any idea whatsoever of what price I should sell it at. I do understand it's a lot of work, so yeah...

Dave, I think it'd be interesting to compare the average selling price of the stuff you tear down/review and your estimated manufacturing price, i.e., you'd count the number of resistors, caps, the different ICs, etc., check the price on some large scale distributor, guess the price of the soldering, package building, assembly, etc., sum it all up and just, well, briefly comment on it. For most of the stuff I guess you could just use your knowledge of the industry...

How important is it to have 100khz testing frequency? I'm trying to decide between this and the bk precision 879b you reviewed, but I haven't been able to find anything. Does it have something to do with testing in circuit?

I see that this LCR meter have ESR function. Datasheet doesn't say if you can use it directly on soldered capacitors. Can you test it in review? Is voltage in that mode less than 0.2V?

@KiloSierraAlpha - Sorry to disappoint, i personally think this LCR meter is more sophisticated than an IPad2, which really is just a typical computer architecture i.e. CPU or rather a micro-controller, RAM, I/O etc. As Dave mentioned the input protection of this device is an art of electronics design, can get very sophisticated. Maybe the programming of IPad2 can get very sophisticated?

Stay away from any Applent AT series lcr color touch screen lcr/esr meter. i bought an AT826 100Khz top of the line, it can't even read a precision resistor right. it does not read any ceramic caps right, metal film, poly's, wima etc... all wrong, will not give you proper readings, not even close. esr is 10ohm+, all my new caps show bad dead, dead, dead, blown up, rubycons, panasonics etc. i bought it from the a distributor and the both said it works despite 1 gig of video and pics uploaded.
