content: Hi guys, I could not decide between Agilent u1733c and Tonghui TH2822C since both have some issues, ended up buying Phluke PM6304 (google it to find out why it's "Ph")Don't have any pics yet but looks like this:I will post a teardown later. That thing is absolute sex.Question: does anyone else have the 63xx and can you tell me the model number of the connector that comes with leaded accessories or at least post some high res pictures of it?. I know it's a 8-pin LEMO 1B series but don't know which exactly it is. I want to make my own SMD tweezers since the Fluke tweezers are $1100. No fucking way I'm paying that for a kelvin clips with a $36 connector.

content: Sure looks nice as hell but as always the biggest downfall of fluke/phillips or just phillips was that they used really weird connectors for their metersWhether cap measurement or temp measurement or even resistor measurement!

content: Those things are awesome.I was fixing a broken oscilloscope a year ago, suspecting the caps were the problem, but I didn't have an ESR meter. I asked one of my teachers at the university if he might have a ESR meter lying around somewhere. After grinning like a maniac for a while and telling me repeatedly that he's got "just the right thing", he handed me that Fluke. A bit of an overkill for simply measuring ESR. I ended up spending more time measuring random components, coils of wire and all kinds of other stuff I could find in the lab, than measuring the caps.

content: I never knew why they couldn't fuse the component measurement connector together with the Voltage measurement nodeQuote from: Tuomas on November 04, 2012, 09:12:07 am... What i'd do after getting a ESR meter for the first week, measuring everything!

content: we got this machine at work. 8051 based. very simple construction inside. but it works really well.i can look up the part numbers monday. there is also an adaptor that snaps into the mini banan jacks.i'll take some pictures of all the heads.

content: Lemo part numbers seem very complex at first glance but they really aren't. You know the series, that is the most important thing to know. Just have a look at their catalogue, it is very good and well explained. You now only need to figure out what kind of contact insert you need, it's either all female, all male or a mixture of both. Of course, if Fluke used something proprietary then you might be out of luck. Good thing is, Lemo make you any contact insert you want even in qty 1. It'll cost you, though.

content: Ah memories...Used plenty of these in automated production test gear.I used to have the service manual for this, but sold it along with a faulty unit a few years back (I used to have several of these units).I remember being able to get the MELO connector to make custom test leads, but this a decade ago now so forget the details.Dave.

content: I use LEMO in all my stuff, from the electrical to the hybrid fiber connectors - many thousands of them. They are really amazing. The part numbering system requires it's own Phd led team to decode. Mouser keeps pretty good stock on the usual parts. If you can understand the part numbering you will find that you do not need an exact match. Just the right shell and pins. Half the part number is the plating, collet size, strain relief, etc.

content: Quote from: rx8pilot on May 28, 2015, 11:31:36 pmAt a former job we used Lemo a lot. Nice parts - super expensive.I suspect the posters do not want to buy a crimper - so they want a solder version. 8 contacts in a 1B shell - I'd suggest anything that starts with FGG.1B.308.CLAD and doesn't end with Z. Mouser has CLAD42, 52, 62, and 72 - which refers to minimal cable diameter - 4.2mm, 5.2mm, etc.Full description of part numbers here:http://www.lemo.com/catalog/ROW/UK_English/unipole_multipole.pdf

content: I have two PM6303A (the little brother) and two PM6306 (the bigger brother) of the PM6304They work extremely well.Every year the calibration is spot on and they never needed to be re calibrated.The PM6306 is still being sold today by Fluke.Fluke never offered the LEMO connector separate but only with the official Fluke cables and they are just outrageously expensive.I bought a few of the LEMO connectors a few years back to make my own cable sets.If you are still after the part number, let me know and I will look it up.

content: oh yesssIt is a good one, passed all tests .... firmware version 1.7Just found out the banana cables, in medical equipment's surplus, ultra flexible "somewhat silicone wrapped" type multi stranded copper wire, with an 0.007 ohm in short circuit tests with the pm6304?Bought 10 kits (2 black and 2 reds per kit), been told that maybe another kits may appears .....Just added kelvin clips and i have now a full working unit with lot of spare cables kits.Found out about the LEMO connector a 25$ ish priced, shipping not included. Not sure about an shielded cable i could put on this plug, i have 50ft of a thin and flexible rg174 cable rated at 2.4 gigs of signal ??

Bulletproof.

content: The DC test option board # pm9565 doesn't exist anymore, unless you find a damaged lcr with it, you're in no luck.Since the schematics exists, i will build one myselfIn Canada Digikey has all the ic's and diodes and transistors and the 2 relays, the hardest to find is the mma0204 resistors, the board has a lot of strange values for a total of 37 resistors parts including the resistor network chip.Trying to find a free cad design software.

content: Congratulation, I pretty sure you will love it.Scored similar brethren of yours while ago, its PM6306 and did a tear down ->HERE.Also in that thread, there are discussions and photos about the test probes accessories for this particular LCR meter.Quote from: coromonadalix on April 06, 2017, 03:04:33 amReally eager to see how you do it as I want one for my self too.
