WHAT DO YOU FOLKS WHO KEEP LOTS OF METERS AROUND DO ABOUT THE BATTERIES, SO THEY DON'T LEAK?


For the Fluke 189: use rechargeable batteries (Eneloop low self discharge). I don't know if rechargeable batteries can't leak but I have never seen it. And in the case of the 189 this is a good idea anyway, as that meter uses batteries like a camel uses water.

I never counted ...

Here are some of my benchmeters
I really curious to know what you're doing with all those meters?

Mainly for certification of test stands for sensors and many other parts in a process analysis. Most of the time, 4 1/2 digits would be fully sufficient but with the partially stupid advent of high level process analysis, one is required to record two more digits for the calculations.

Also, I have several test stands in the field, where we measure precise voltages up to 1000 V DC directly with a DMM and we use data acquisition to collect the values. The Keysight 34401A and the 34461A have been the standard for these type of measurements for years.

There are 3 kinds of people in this world, those who can count and those who can not.

I think I should create a new thread with the title "How many bench LCR meters do you own ?" and waiting for your post.  >:D  :-DD

I'm honestly afraid to count.

Same here ... but my "collection" is not worth mentioning.  The apex member is an EEVBlog BM235.

In my expirence it is not using much battery, but my 289 is bad.

About the count:
Bench DMM's: about 10 (Fluke, Keysight, Tektronix)
Good handheld: about 10 (Fluke, Keysight, Gossen, Brymen)
Cheap handheld: more than 10 (This number will increase significantly in the near future due to my reviews).

I have two DMMs, both Fluke 115. I was introduced to this model at work, and even though they're not the cheapest, I got two for my home lab, since I know I'll not have to worry about build quality or anything like that.

How many DMM's do you own ?
« Reply #60 on: October 18, 2017, 02:14:38 AM »
Save some space on the rack guys. Anyone selling their ? I was thinking of getting hand held and then realized a bench dmm would be better. At the moment I don’t see myself getting one any soon.
I have the rigol, bk keysight in mind. I like the rigol display and have their oscilloscope as well. To start with i am looking for 4 wire resistance measurement with a resolution of 0.01mOhm and better sample/sec reading. Rigol has about 25s/sec and other features are bonus.

Any recommendations would be appreciated. My budget is 300-400$.

For the Fluke 189: use rechargeable batteries (Eneloop low self discharge). I don't know if rechargeable batteries can't leak but I have never seen it.

NiCd and NiMH cells have a pressure vent for safety at the positive terminal.  If the cell is old enough or severely overcharged, it can leak but the result is usually crystals of potassium hydroxide and not nearly the mess that other batteries make.  The positive end of the cell will look "fuzzy" when it starts to leak.

Two good ones:  A Fluke 179 and a Fluke 16.  The model 16 is smaller and simpler; the 179 is slightly more capable and I usually prefer it, but for most tasks, either one will work well.  These are the ones I use almost always.

One tiny simple rugged one that I keep in the car: A Triplett 1101.

One feature-rich one with horrendously terrible ergonomics that make me hate using it: A TPI 440 scope meter.  It's been a decade since I've used it, I think.

Three that I keep around for nostalgia's sake and because it's not worth the hassle of selling them, but I don't keep batteries in them and can't imagine I'll ever use them to measure anything:
  • A Micronta 22-027A analog meter, 1000 ohms/V.  I bought it about 40 years ago for $7.95. It still has the price tag on the box.  It's tiny.
  • A Micronta 22-185A that was my first digital meter, and my first meter with a reasonably high input impedance.
  • A Centech something or other that I got practically for free at Harbor Freight recently, because I was curious to see how bad those things are.  It's surprisingly accurate, if it has a fresh battery in it.  But it's junk construction.

Right now I got 9 modern bench top DMMs (all purchased broken): 5 already repaired and 4 are in the process of being repaired.
I also got 2 cheap Chinese handhelds and Fluke 189.

Fluke 189 and DR-5000 LCR meter are the most used of them all.

(Yes, I know DR-5000 is not a DMM).

FWIW, I also have a DER DE5000 LCR meter, but didn't include it given the title of the thread.

That said, it's a wonderful bit of kit for the money IME.  :-+ I couldn't even get an HP 4274A boat anchor* for what I paid for the DE-500, extra options I ordered, and fastest delivery. BTW, both of these can test up to 100kHz, and the 4275A up to 10MHz.

Seller with DE-5000 + all accessories with free tracked shipping goes for $163.49 (here). :o  ;D Add $5 for an intermediate delivery date (by the 9th of Nov.), and $15 for fastest delivery (by the 31st of Oct.) at the time of posting this.

DE-5000 LCR + TL-21, TL-22, and TL-23 (no power adapter or software kit) goes for $108.99 shipped (here).

* Quick look on eBay brings up $500 OBO + shipping for an HP 4274A (it may be possible to get one for less than the linked unit + cost of repair, but I didn't bother with investigating this).

Nano, have you gotten rid of those annoyingly short alligator clips and substituted these in? https://www.ebay.com/itm/LCR-Meter-Test-Leads-Lead-Clip-Cable-Terminal-Kelvin-Clip-Wires-with-4-BNC-/181391981262?hash=item2a3bcdface:g:uVMAAOxyUylTWduc

I got a set, they work well though one of them was shorted.  Simple fix.

At this point I were searching from the web what the DMM 4275A looks like as it can measure up to 10MHz  .... Yep, I'm disappointed it is a LCR-meter.  |O
Pick your point and call it as a ground.

No, not yet.

I figured on DIYing my own using silicone wire I already have on hand (still need to buy the Kelvin clips).

I like it as an LCR meter, but despite their age, they still go for a lot of money. And it's this bit I was frustrated with (same with the 4274A).  :(

Though it wasn't a primary reason for buying it, the portability of the DE-5000 is nice to have IME.

When repairing/troubleshooting stuff and no high accuracy is required, I use normal DMM banana probes on DE-5000. They plug in just fine. Yes it is only 4 wire till the jacks and I am adding about 0.3 ohms to ESR reading. It is a great convenience when you need to get into some tight spots, and you can subtract that 0.3 manually.

I got a set of these to make poor man's kelvin clips for my GW-Instek GDM 8251A  https://www.ebay.com/itm/2PCS-For-Copper-Gwinstek-LCR-Kelvin-Test-Clip-Bridge-Test-Microresistivity-Clamp-/142267585778?hash=item211fcf14f2:g:QM4AAOSwo4pYlXc3

I added Franky's banana plugs and have a decent set.

FWIW I've been considering a pair of Mueller BU-78K Kelvin clips to go with retractable & stackabe banana connectors in red & black I already have on-hand (copies of Mueller BU-32614). But given the cost for genuine Mueller BU-78K ($50.92 per), I definitely need something less expensive. So I'd been looking at clones of the BU-78K (example), which go for $13 for a pair shipped.

That said, the one's you linked look decent as well, and are similarly priced at $14.35 for a pair shipped.

Strictly DMM, I guess it's currently 17: 9 bench (three in the repair queue) and 8 handheld. They represent a nice assortment of display technologies: Nixie tube, segmented LED, dot LED, VFD, and LCD.

Not DMM are a few good old analog voltage and current panel meters.
It's TEA time! You know you want some.
