content: i have a bunch ( 10's of thousands ) of nos ceramic dog bones and the markings are a bit hard to read so im in need of a lcr / capacitance meter that can read down to 2pf.but i don't want to spend several thousand dollars or hundreds for one.so dose any one know of a low cost one that can do this?and the tek#'s are non existent on 80-90% of the packaging, so i cant cross ref them.

content: der ee de5000 lcr meter. around $100 shipped from japan. you can find them on ebay.don't forget to get the tl21 and tl22 probes with it.http://kripton2035.free.fr/LCR%20meters/lcr-deree5000-cl.htmlhttp://www.ebay.com/sch/i.html?_nkw=der+ee+de+5000&LH_PrefLoc=2&_sop=15

content: Quote from: kripton2035 on May 14, 2017, 03:03:36 pmi looked at this one but the spec say it only goes down to 200pf and i need 2pf -10pf at the lowest i have some that are down at 2pf that i crossed and was able to read the color codes on.after re-looking at the specs lol i was looking at the range, and not the resolution.

content: yes - resolution is 0.01pF ! (or 0.1pF depending on the measurement frequency)

content: this one is cheap and work down to 2pF, 0.01pF resolution. and has been reliable to me. but it only measure L and Chttp://www.ebay.com.my/itm/LC200A-Handheld-Capacitance-Inductance-L-C-Meter-LCR-Multimeter-Electric-Bridge-/172659599511?var=&hash=item2833506897:m:mf2s2bzqhbnw_JuCQDgo8kQthis one is cheaper kit and pretty much measures everything, but i havent time to assemble mine.. and not sure about the resolution.http://www.ebay.com.my/itm/M328-LCD-12864-DIY-Transistor-Tester-Kit-Diode-Triode-Capacitance-LCR-ESR-Meter-/161913228003?hash=item25b2c7cae3:g:R7gAAOSw5HJXKYm1

content: Quote from: Mechatrommer on May 15, 2017, 12:22:06 amAs for the 2nd unit, the smallest capacitance it can measure reliably is about 10-15 pF. Usually I have trouble measuring lower than 30 pF.Its ability to measure small inductors is even more limited.

content: I would go with the de5000, offers more ranges and values than the lcr200, i know it's higher priced, but will be more professional, unless you gauge all your values and dont use the lcr afterwards

content: Quote from: coromonadalix on May 15, 2017, 03:43:10 ami have been think about that one. ( it was my first thought but i didn't think it would go that low, the specs don't say how low it goes. ) i have some inductors, and other components as well and that one i think will be the better bang per buck / and usfull. so i think that is the one i will begetting.and as you said it offers a lot more ranges, as well as features, that i can use, and more professional / robust.and thank you all for the help on this question.
