For the price of UT181A you can get a used 289.

In watching the workflow of the 289, the menu system gets in the way at times. The 181A uses a menu system as well, but had moved some functions out to one-touch buttons, which I like. Also, the 289's screen is one of the dimmer in Fluke's line. I imagine that both of these lines are due for a refresh to touch-screens, but I'm not sure when that refresh will hit the market. Also, I'm not sure how safe touch capacitance screens are. Perhaps touch screens won't make it to DMMs for safety reasons.

blueskull, as an owner of a Fluke 289, would you choose the 289 over a new 181A?

Surprised the Fluke 87V failed at 1.5KV/2ohm. I'm new at this - is that under CAT III specs?
We all were.  :scared:
There's one hell of a lot of info in that thread, not just about DMM's but Joe's journey too, and the whys and why nots he's tested DMM's in the way he has.
Many get somewhat precious when their favourite DMM scores badly according to Joe, but don't skip through the thread too quick, you'll come out much wiser if you take the time to follow it through.
Me, the Fluke 15B is all I need for a portable DMM, they were intended for the Chinese market only and you used to be able to get them on eBay or Aliexpress but they've been superseded by the 15B+ and 17B+.
They're still quite adequate for basic EE needs and Dave's rebadged Brymen is a good bet too. Joe rated it highly.

If I can get a brand new 289 for the price of a 181A, then a 289 is my definite choice.
For a used 289 at the same price, I frankly do not know.
At the time I bought my 289 there was no 181A yet. Ironically, I bought my 289 from a Uni-T dealer.

To confuse you more, there's this great thread too:

Hahaha - thanks  :-+!
I actually found this at the start of my search. It's been really handy to have a DMM list of mid-level to professional models, all in one place like this. It made it a little easier to spot ODMs in this market. Honestly, I'd love to get a Gossen, but at those prices, I think they are made out of rare German unicorn feathers. Those German unicorns are extra well engineered.

If I have the money, I would like to have a Gossen 6.5 digit handheld meter. The ppm accuracy is as good as benchtop ones!

I am a bit amused at the meters being considered given the title of the thread.

Need recommendation for ^really frickin' good starter DMM.

Seriously though, everyone has been super helpful and I feel much more informed about the DMM market, and how to vet a purchase. The video blogs from both Dave and Joe Smith are immensely informative. Exactly what I hoped for from an engineering forum.

I was responding to post #16. The measurement of a PWM signal is called duty cycle, which is found on some DMMs, but most do not have it. In practice it is seldom needed because you can just measure its DC component.

Ah, pulse width modulation.

Quote
However the Frequency and mark/space (PWM power ratio %) is so freekin' handy when doing arduino control stuff.
This is really helpful, since I plan on getting further into arduino, and I'm guessing this type of signalling is used in bus control protocols at a "layer one" level (if I can borrow OSI networking terms).

Measuring the pulse width of a servo pulse (1.0 .. 2.0 mS wide pulse every 20 mS (more or less)) is pretty handy.  My Fluke 189 can do it but my Brymem BM235 (EEVblog) meter can not.  Yet the BM235 is a respectable meter and I bought two of them.  I gave one to my grandson (he's just starting EE school) and I kept one on my bench.  Same story for measuring higher frequency PWM for H-bridge motor drivers.  The frequency is sometimes too high so a scope does a better job.

One nice thing about the Fluke is that it tells you if you have the probes in the wrong holes for the range switch setting.

The EEVblog logo on the BM235 is pretty cool!

And, yes, it's never to early to think about a scope.  When you need to see what is really happening, a DMM is the wrong tool.  DMMs are good for measuring static kinds of things like AC/DC voltage, current, capaciance and resistance.  But when you need to see something that is changing over time (particularly short time), you really need a scope.

There are dozens of threads in the Test Equipment sub-forum.

Yes. You will want to buy it directly from the eevblog store since you're in Europe. It's currently out of stock, but they are generally still available.

You can also pick up the non-eevblog version. You'll miss out on the sexy blue holster (you get red instead) and maybe the banana probe adapters, but I think it's otherwise the same meter.

is that an online store ?
I would like to support EEV, buying directly from its store.
What's the price ?
I can wait a bit, no big deal.
Cheers

As Dave and other community members have mentioned, it is nice to have more than one meter for comparing measurements.
For a sanity check meter, does anyone have a recommendation that wont break the bank?

I figure its not worth sending my fluke 87 to a cal lab periodically.

I've asked Dave in this post but you probably won't be able to see it unless you've got access to the Supporters lounge.

I'm going on holidays so have shut down my store until mid Jan.
Will be back available on Amazon in a few days, but only for US and Canadian customers.
