Ive been looking on ebay and found this one http://www.ebay.com/itm/New-M6013-Au...-/191042485217 I like how its auto range but it looks sorta cheap, which would be the best quality, it doesn't have to be super accurate but i would like a ballpark figuere.

Re: curious about capacitor checkers.
Says on the website...
Accuracy:
0.01pF to 47.000nF 1%+2Digit
47.00nF to 47.000uF 1%+1Digit
47.00uF to 470.00mF 1 to 3%+1Digit (Larger capacitance will have larger error)
Not very useful I suppose... but I'd say it's fine for most use, especially with big electrolytics.
If you wanted to do some high accuracy check of pF size caps for RF work or something then I guess it wouldn't be good enough"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: curious about capacitor checkers.
No ESR check function either it seems. I'd look elsewhere.I love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Re: curious about capacitor checkers.
1% is pretty good, lytic cap has +/- 20 % Tolerance, most small polyester has 5% (J), or 10 % (K) Tolerance.Never stop learning

Re: curious about capacitor checkers.
$134 is too much; here it is for $27 including shipping:
http://www.ebay.com/itm/M6013-V2-Aut...item4d0d329c0e
But, it will only test capacitance, not ESR or anything else.
If ~$120 is within your price range, take a look at DER EE DE-5000.Comment

Re: curious about capacitor checkers.
If you want an all around good multimeter, you can't go wrong with this one:
http://www.ebay.com/itm/UNI-T-UT-61E...item2ec6ac75bd
The ebay seller is well known on eevblog (electronics forum) and you can trust that ebay store and guaranteed fast shipping and not dead on arrival (he checks every one before sending)
It measures up to 220mF (220.000 uF), it's 22000 count meter so you get a fine resolution when measuring voltages, it has data logging, fast continuity etc etc and it's only 53$.
It does not measure ESR ... for that you'll need an ESR meter.
To fix stuff, an ESR meter is more important than a simple capacitance meter because the esr meter tests the cap at high frequency... there are lots of cases when capacitors still measure a good capacitance (value +/- a few percent) with a multimeter (because multimeters measure at 100-120 Hz) but when running at high frequency in circuit, the capacitance drops and capacitor fails.Comment

Re: curious about capacitor checkers.
I know these are kind of frowned upon by some but I bought one of these Chinese transistor/ESR/inductance DIY knock-offs and it works surprisingly well and accurate enough for what I do. I mainly bought it for testing ESR and capacitance after shopping around for quite a while and this one seemed to be the best for the price for testing ESR. I've also found the diode and transistor testing to be helpful.

I have another multimeter that measures capacitance but not ESR and is rated more accurate than the Chinese unit and so far all the caps measured agree between the two.Last edited by SteveNielsen; 05-16-2014, 09:31 AM.Comment

Re: curious about capacitor checkers.
Exactly. The other meter I mentioned is a Mastech MS8264 when I was looking for a good temperature meter with probe and is another case of shopping for a particular function for a hobbyist price. I'm very pleased with it as well. I mainly use it on the temp function when calibrating my soldering station when changing or just checking tips, another cheap thing that actually works very well.Comment

Re: curious about capacitor checkers.
yes just looked on ebay uk about £22.50 inc postage i dont have a temperature meter and probe so maybe worth getting one i guess its a handy meter to have.Comment

Re: curious about capacitor checkers.
I got mine for $35.50 usd under a promotional free shipping from Amazon. That's close to the same price.Comment

Hi people, I hope this is the correct spot to post this, I'm new to the forum.
I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.
I hope these photos make it clear which component I am referring to:
(yes, the soldering is a bit botched from removing the blown one, I know)
I have found the board schematic (attached), but there does not seem to be a boardview available. I have never... -
I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
I know that these capacitor will not last as long as nichicon capacitor... -
I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm
And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,... -
When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
Rubycon YK DataSheet (b... -
a few days ago I finally purchased mser-100 v2 and I tested its abillity of measuring ESR value.
I found that It shows pretty accurate ESR value for electrolytic capacitor,But When I measure polymer capacitor of dreamcast game console,I found that one third of polymer capacitor's ESR value is more than twice the value of ESR meter table.(for example, I measured one polymer capacitor of 6.3v 100uf, It showed ESR value of 7.68)
Although my dreamcast now turns 20 years old but it still works. I occasionally have played game with it.
Is this ESR value of polymer capacitor correct?...
