jimjimbo Posted January 2, 2017 Share Posted January 2, 2017 @BEC and @Deang https://www.amazon.com/5000-Handheld-LCR-Meter-accessories/dp/B00S298KJO/ref=sr_1_1?ie=UTF8&qid=1483399682&sr=8-1&keywords=der+ee+de-5000 Received this meter today, and got out a bunch of new and old caps to measure. Measured several values at test frequencies 100hz, and 1Khz. All of these were on my bench and not in circuit. What I would like to have is a couple of older caps that Bob has measured on his meter, so that I can compare to my meter readings. I think this would be a good way to confirm accuracy.

BEC Posted January 2, 2017 Share Posted January 2, 2017 Looks like it has enough resolution to pick out bad caps, but not enough to really evaluate good caps. Also, might as well just standardize the test for 1000hz for crossover caps. Bob Crites Quote Link to comment Share on other sites More sharing options...
Schu Posted January 3, 2017 Share Posted January 3, 2017 What do you need for that bob... a meter that reads to ten thousandths or higher? Quote Link to comment Share on other sites More sharing options...

jimjimbo Posted January 3, 2017 Author Share Posted January 3, 2017 Bob, what would be a good ESR reading for a 2uf, 4uf, 8uf, etc, etc? I realize it's dependent on the value, but do you happen to have a basic chart, or just in your head? Would you consider all of the Aerovox readings above bad?

Well I think it certainly tells you if a cap is good or bad. To really read the good caps, seems to me it needs another digit of resolution. The Aerovox read like I usually find them. All the 2 uF are pretty bad like I usually find them. I think ESR becomes pretty easy to hear at above 0.5 ohms. Quote Link to comment Share on other sites More sharing options...
Deang Posted January 3, 2017 Share Posted January 3, 2017 I like it, it's plenty good enough. It would allow me to test new caps before I use them to make sure they aren't shorted, or have a measurement that makes the quality suspect. I have no interest in measuring old capacitors - I already know they're toast. 1 Quote Link to comment Share on other sites More sharing options...
BEC Posted January 4, 2017 Share Posted January 4, 2017 B&K Precision now makes some meters less expensive than my B&K 885. You should look at the B&K 879B and 880. You can find the 879B for around $250. Bob Crites Quote Link to comment Share on other sites More sharing options...
jimjimbo Posted January 4, 2017 Author Share Posted January 4, 2017 The 880 is the way to go. Check out the datasheet, and the included test probes, other accessories...that the 879B doesn't include. https://bkpmedia.s3.amazonaws.com/downloads/datasheets/en-us/880_datasheet.pdf Quote Link to comment Share on other sites More sharing options...
BEC Posted January 4, 2017 Share Posted January 4, 2017 Yes, looks like you have to get the 880 to get the Kelvin test leads and DCR. Quote Link to comment Share on other sites More sharing options...

Depending on the manufacturer's tolerances, they're likely within spec and those measured numbers are not unusual. I don't see anything wrong with them.

jimjimbo Posted January 13, 2017 Author Share Posted January 13, 2017 I take it that you are referring to the capacitance values not the ESR values which is what we were looking at Quote Link to comment Share on other sites More sharing options...
mboxler Posted January 13, 2017 Share Posted January 13, 2017 I've had the DE-5000 for a while. Only drawback...the short alligator test leads, Bought this, hoping it would fit the DE-5000, and it does. Main issue with this though, is the clips don't grip very hard and the cable is pretty stiff. But the added length comes in handy. https://www.amazon.com/gp/product/B005T710WG/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Mike Quote Link to comment Share on other sites More sharing options...

Would love to have longer leads, but $83 is a bit much for what I need it for. So far, I've found it's a pretty good meter. Quote Link to comment Share on other sites More sharing options...
