Thanks Nano Frog.
I find the continuity (beeper) function very usefull when you are looking for tacks on a PCB. Usually I do it relatively fast by making contact with one pin or point on the PCB and randomly running the other probe across the board. I use a Fluke 175 at the moment and I never had any problems doing so with it. I was just wondering if on that particular application the U1272A was slower and perhaps a real pain in the neck?

For some good info, I suggest you watch Dave's video about a problem he had:

and teardown, if you're interested in that:


I'm in New Zealand, and when faced with the same decision, I got the 87V and I'm really glad I did.
Regarding price, the official NZ RRP has reduced by nearly half over the last year or so.
Currently in NZ, RRP on the Agilent U1272A is about NZD$600 and on the Fluke 87V it's about NZD$660.
Also, I emailed the 2 official suppliers (element14 and RS components), requesting a quote for the best price they could do.
I went with the best price offered, which was RS as it turned out.
Try emailing Deepak at RS, he gave me a good discount.
Dee.Sharma@rs-components.com is his email address. He is in NZ.

Hi samgab,

 I have indeed watched those videos before I started posting and apart from the tear down video which was very detailed and helpful the so called "FAIL" video didn't really go into too much details and certainly not compare the two meters. I would like to know why do you say

Could you please explain?

I see Agilent has been very good to address the firmware issue and fixed it.

Yes, you're right; I saw that Agilent offered the firmware update to that problem, that is good. When I first posted that, I'd forgotten that the teardown was done, but Dave doesn't seem to have gotten around to doing the actual full review on the U1272A.
I just meant that I'm happy with the 87V; it doesn't have any fancy features, but it's a simple, no-nonsense tool that just works, and it works really well at what it's designed to do.
I saw the bugs in the first video (which have been sorted out in the firmware update) and I saw the problems Dave had uploading data from the U1272A in the resistor averaging test video, and it just didn't seem to... I don't know... be mature in the market yet or something. Just a general feeling of a lack of confidence in it. But that might be unjustified.
I must say, I would really like to have a data logging function though, but the Fluke 289 was out of my price range.
Also, the use of AA cells in the U1272A is preferable to the 9V battery in the 87V.
So there are some advantages to the U1272A I suppose.
The continuity seems fast on the U1272A too, unlike on their OLED model; was it the U1273A that was slow?

I suppose, writing about it now, both are good meters, and the U1272A has several advantages over the 87V (AA cells, data logging, 2 part display, 30,000 count, fuse access via door...)
What I guess I mean about being glad about buying the 87V is - not in comparison to the U1272A - but just in general I'm happy with it; but I'd probably also be just as happy with the U1272A.
I like that the 87V is made in USA and has a lifetime warranty. I don't know where the U1272A is made, and it has a 3 year warranty.
Accuracy of both on the DCV range is 0.05%, but it's ±1 count on the 87V (in 6000 count mode) vs 2 counts on the U1272A (in 30,000 count mode on some Voltage ranges). So hardly any difference there, although the Agilent wins by a nose.

Dave said that Agilent put the U1272A out to compete head to head with the 87V. I'd love to see an in-depth video review by Dave directly comparing those two side-by-side!

PS: another advantage of the U1272A: Current defaults to DC!

ME TOO!

I guess I was hoping for someone to say, "look here is the comparison" Fluke has the name and reputation, but it is in my opinion way too pricey. The U1272A is about $100 cheaper than 87V at the moment on E14. So this is why I am asking. All that really matters is longevity, accuracy, price(of course) and robustness. And what about the continuity test, anyone out there own a U1272A How good is it? Fast enough?

Did you see this video:

Looks as fast as the Fluke in that video to me. But I haven't used the Agilent first hand.

...I saw the problems Dave had uploading data from the U1272A in the resistor averaging test video, and it just didn't seem to... I don't know... be mature in the market yet or something.
Not sure if it helps, but there's a newer software version out now (current revision is 1.5.0.0, released on Oct. 18, 2011). I never tried the older version (got mine in Jan. 2012), and I've not played around with it that much.

But it's also possible to export the data in a .cmv file, and use it in another application, such as a spreadsheet. Getting the data from the meter was rather easy, as was exporting it to a .cmv file. So YMMV, but I don't think it's that big a deal, especially when compared to what Fluke charges for the FVF software + cable kit (presume it's even worse in NZ).

Just a general feeling of a lack of confidence in it. But that might be unjustified.
I must say, I would really like to have a data logging function though, but the Fluke 289 was out of my price range.
I was looking at a Fluke 287 for electronics use on a bench (don't work in industrial settings, so features like ZLow aren't important to me). Amazon offers it here in the US for a bit over $400USD ($406?), which is for all intents and purposes, the same as the MSRP for the U1252B ($410).

But the fact that the Agilent throws in a calibration with data, and they were offering a $100USD rebate at the time I purchased it (I even got it for a little less than MSRP), it made a better deal. And that's before considering the cost of using the software, which only adds the price of a cable in the case of the Agilent ($30USD IIRC), vs. the cost of the FVF kit.

In terms of Bang-For-The-Buck, the Agilent made better sense for me.

I've no idea if the Agilent will hold it's calibration or will drift over time, making calibration necessary in order to trust the readings (if you can't trust it, it's useless IMO, save as a fancy paperweight). I don't expect this to happen, so if it turns out to be a bust in terms of accuracy over time, that would force the purchase of a 287 (I will probably still get one at some point, but there are other purchases that I will make first).

I don't know where the U1272A is made, and it has a 3 year warranty.
They're made in Malaysia.

Keep in mind, Fluke's warranty isn't what most would consider a lifetime warranty though. It's between 7 and 10 years according to Fluke's warranty page. Bit confused myself as to the details, as I'm under the impression it depends on a combination of the date of purchase, when it goes EOL, and available spare parts (i.e. if it dies 7 yrs + 1 day, and there's no spares to repair the unit, will they give you a new meter or tell you "sorry, it's no longer under warranty" ???). I don't think it's a major issue, but it's what you don't expect that can take a big bite out of your wallet.

I guess I was hoping for someone to say, "look here is the comparison" Fluke has the name and reputation, but it is in my opinion way too pricey. The U1272A is about $100 cheaper than 87V at the moment on E14. So this is why I am asking. All that really matters is longevity, accuracy, price(of course) and robustness. And what about the continuity test, anyone out there own a U1272A How good is it? Fast enough?
Overall, the U1272A compares really well from available information (specs and video reviews). What we don't have, is sufficient history to base long term reliability and accuracy on, as Agilent has been absent from the handheld segment for some time until they bought Escort.

So in that regard, I and others that have bought them, are taking a gamble (why I suspect they offered the rebate in the first place, as they need to get their products out into the field since their standard MSRP's are too close in order to gain a market presence). Particularly when comparing the U1272A and 87-V.

I also did a detail review of the 1272a, its somewhere on eevblog and in the net.  Bottom line, price being equal the 1272a is a better deal vs the 87V as it offers the same accuracy, while providing far more functions.

I've used Flukes since the 1980s and its hard to beat a lifetime of experience.  That said, the 1272a is a worthy competitor, and the 87V typically sells for about $330, delivered, check Amazon.com pricing as example.

The only drawback I find in the end, is ergonomics.  The LCD's smaller digits, and more annunciators on the screen make for a cluttered appearance, and after stress testing it for almost a year, is does get annoying.

If you need a logging DMM for field use, the 1272a is clearly the winner as the 87V has no such feature.
Best Wishes,

Thanks so much guys, your posts are very helpful!
I decided to go with the U1272A and will shortly buy one. I will of course keep you posted on any good and bad experiences I encounter.

Hi Folks,

I'm keen to see how well the Agilent U1272A performs so I'll have one in a few days time to review on my YouTube Channel.

Oh fantastic! Can't wait to see your side-by-side comparison of these two... They're both excellent DMMs seemingly, I know the 87V is... But the U1272A is a bit cheaper and brings a few extra features to the table...

Yup, I'm keen to see how well the U1272A does in comparison to the Fluke 87-V. I've just completed the review of the 87-V and it'll be up tomorrow.

Cheers,
Martin.

Anyone could tell me what comes in the box when you order the U1272A on Element14? I see they sell the U1171A Magnetic Hanging kit separately?

According to the Quick Start Guide (http://cp.literature.agilent.com/litweb/pdf/U1271-90000.pdf)

  • Meter
  • One pair of red and black test leads
  • One pair of 4 mm test probes
  • One K-type thermocouple lead kit
  • Four 1.5 V AAA alkaline batteries
  • Printed copy of the U1271A/U1272A Quick Start Guide
  • Printed copy of the Certificate of Calibration

For a picture of the leads, take a look at the U1169A set (http://www.home.agilent.com/agilent/product.jspx?cc=US&lc=eng&nid=-536902470.892751&pageMode=OV). You might get lucky, as this may actually be the set in the box (would give you 19mm probes as well), even though the Quick Start Guide doesn't list them.

This was the case with the U1252B I picked up anyway, which is why I mention it (included Alligator's too, but those were listed on the Quick Start Guide for that model, unlike the 19mm probes).

As per the quality, they're decent. Much better than the stuff I usually see on eBay or come with lower cost meters, and the wire used in the leads is 16AWG silicone insulated rather than PVC. They don't have the "wet noodle" sort of flexibility that Fluke/Pomona leads do, but I'm hoping that will work out with additional use (not horrible by any means, but a bit more flexible would be nice).

Hope this helps.  :)

You could also check this review: http://tronixstuff.wordpress.com/2011/04/01/review-agilent-u1272a-true-rms-digital-multimeter/ which shows the items in the box. I'd say it would be the same in NZ.
