DMM with Graphing capabilities at a decent price

[+sync]

First of all, I'm a total newbie, and that must show - sorry for that!

Then, thank you for the amazing piece of work - that excel spreadsheet is great.

However, I don't see what gives "graphing capabilities"  (I might see "Logging", which is linked to that, but "Graphing" is the next step, ie "Log + Graph").

Would you mind to point to something decent at a decent price (<= US$300 if possible or not so far), provided that

- it has graphing capabilities
- at least 1000 points in memory
- the work is mainly computer electronics, up to ~30V, ~10A, usually DC
- nice display if possible

Thank you.

A used Fluke 289 or a new Uni-T UT181A should both work well.  I know there are others but those are two from the top of my head.

Thanks.

Maybe I should have added I need at least a 20Hz sampling rate (20+ samples a second).

The new UT181A looks pretty good for the price (~$300 on ebay) and its OLED display. However according to a few posts it doesn't sample more than twice a second!

Maybe I need a pocket oscilloscope for graphing capabilities!   (have already an old Kyoritsu 1009 for other measurements)

if its for electro-mechanical  applications?

you could use something like this:

Thanks R_G_B_, it's indeed for electromechanical applications, based on motor... controllers.
But if I understand correctly your post, all these nice graphics require the Vantage graphing mm.
Which, correct me if I'm wrong, is actually a handy oscilloscope.
Which requires also, for current graphing, like most oscilloscopes, a "low amp probe" adding another ~$150 to the system.

Actually, I should have mentioned this earlier but as previously warned I'm more on the dev side. The pros who wander on this site and me may have different needs, in particular:

? the circuit may be cut to install a MM in order to measure current (no need of an external probe).

Thanks blueskull and I like the idea of using Arduino for sampling DC V/A (love C/C++ dev), but building a device myself...  better call the fire dept now...
Would you know any plug n play board based on Arduino (...) or connected to Arduino/other that (all DC)
 • can bear 10A for measurement (or does some tricky electronics bridges to measure it without enduring the power)
 • sustain 30V
 • sampling at 20+ Hz
 • sends collected data to USB (or serial), better real-time but even "after sampling" is OK if that makes it easier to find


Edit note: the "?" above is actually an arrow (unicode). The page being UTF-8, it seems the storage (mysql, files...) on this site is not UTF-8 or anyway doesn't store/load correctly the encoding coming from the page/DB. No complaint. Merely a remark.

It does not need a current clamp it has a port just like a multi meter for measuring current up to 10-Amps which it will graph.

Indeed. The Vantage seems rather old... but if it does the job..

Basically I'm down to either

- the snap-on Vantage thing

- the new Brymen BM525s (sampling up to 20Hz!)

(I give up on having nice graphics...)

How about something like this (haven't used this, but seems nice):

Looks really nice 

Actually... cannot believe it still... just ordered one!

Makes me really wonder what's inside (and what's not) the very expensive stuff .... (security but, still...)
Sounds like the many features are embedded within a couple of chips..

Seriously, all this time looking for something decent, what did I see
- my kyoritsu 1009 still being sold in 2015, for $70!  (bought that many years ago)
- the only graphing stuff sampling at more than 5Hz not-so-expensive is the above snap-on Vantage => 1998 stuff 
- most things sample at 1Hz 

Guys, you won't like it, but I think you are being ripped off!

This new thing is the future. Starting...

This has great capabilities and cost effective.  If you already own or wish to own a Keysight DMM, even its most budget models have IR logging via USB port, I added the bluetooth dongle for $50 and its reliable.  Compare the overall features and maximum data set to see what is best for you.

Hah, ok, if you say so.

Glad you like it. Let us know what you think about it after using it for a little while.
