Agilent U1253A Agilent U1253A
Thanks Alistair.
No, it's unusable while charging. I forget to mention this. This is almost certainly a deliberate safety feature, as the DC jack could potentially be exposed to live voltages from the probes in this case. And it probably wouldn't meet UL type safety requirements in this case.
Seems there has been an uproar over my qualified "thumbs up" rating at the end!, so I've just made another video on this aspect. Stay tuned...
Dave.
Thanks for the review - I didn't watch all the way until the end because once you had told us how it charged (through the measuring terminals so you can't use + charge) I decided it was a waste of space.
An 8 hour battery life is bad enough but if you were caught short at least you would expect to use it plugged in - who can afford to loose an hour or so because a battery runs down !?
The rattle, silly battery contacts, cheapo sockets and inaccessible fuses just add more poo to the ice cream !
Yeah, great review!
Bottom line, I'd rather squint than change the batteries. Esp for that kind of dough. :-)
My followup video responding to why I still gave it the thumbs up when the battery life sucks.
Will be interesting to compare this with the new B model when (hopefully) I get it in the next few weeks.
BTW, Agilent also sell the exact same meter in an LCD version, the U1252A (and U1251A) for those who want to trade OLED for battery life.
I have been writing up a review of the Altera Nios II Evaluation Kit, and these videos and responses have made me think quite a bit about what I have written, and the way I have written it. No videos for me I'm afraid (although I have done a few short silent videos of the product itself) but I think some editing is going to happen before i dare show it to the world.
Anyway, I think the cause of all the commotion has been the shock at seeing how a modern piece of HP (Agilent) test equipment looks when compared to the 'old' stuff. I get the impression that all the engineering effort has gone into the fashionable software area and the hardware design has been farmed out somewhere. I don't care where something is made and designed, but the hardware design does look like it was done by inexperienced people who don't especially care about doing things the best way. It smacks of being a marketing-led product, rather like GM and Chrysler were, not engineering-led.
One of my hates is the cheap squishy rubber buttons many manufacturers use. Perfectly acceptable on budget gear (heaven knows I have specced it myself) but not on quality stuff. Change those, do a bit of PCB re-design, put in a decent Li-Po battery that can run it for a working week (hey, if my cheap phone can have a battery like this, I'm sure this meter can) , get rid of the cheesy tunes is plays and put in a good fast continuity tester and they could charge a chunk more cash for it.
How about adding an induction coupled charge/run dock powered by USB? They could run out the logger data that way without any spike problems. They could probably even charge $50 more for that too!
Hi Mike,
I wouldn't be too overawed at Dave's review, I'm sure he'll admit himself it does take practise to get to that type of standard. I'm sure our readers are interested in hearing about the Altera kit, what it does, and of course what it doesn't do than the actual presentation.
We did do a RoadTest of the U1253A DMM in the Tech First Journal originally, and there are two reviews posted here, I'll link them here so people can maybe get another perspective, although I think they also backs Dave's thumbs up conclusion.

Dave,
Just a small point, but do you think you concentrate too much on the name? I know Agilent are huge, but if the DMM cost the same price and was unbadged would you have come to the same conclusion?
Dave,
I have to admit I was a bit surprised about the thumbs up initially, but on reflection I think I see your point, (more or less) on the whole the negatives aren't show stoppers, it still works, provides accurate fast readings is usable (for 6-8 hours) and brings some nifty additional features.
I think the performance of the display outdoors is a little disappointing, it is after all a ruggedized handheld device, so field use would I presume be a large part of where you would expect it to get used. The battery life seems a bit of an issue, but I suppose 6-8 hours gets you through the average working day, and I guess if you get in to the habit of charging it in your down time, it's workable if not desirable. I assume you can also use a standard PP3 to get you out of a fix if the battery dies. Having read the manual briefly, looks to me like the things out of action while it charges, why not supply with two batteries and a separate recharger (ideally one that will work from the mains and a cigarette lighter socket).
The rattles a bit of an oversight, maybe they should have used sprung connectors rather than cable, but if it really bugs you, you can pack it yourself, I notice the box you had for the U1253A was a little beaten up, I'm guessing it wasn't new, maybe it originally had a little foam filler to stop the rattle and someone's removed it.
I'll be interested to see the review of the new meter, to see if any of the negative issues discussed in your review have been addressed. Will it still get a thumbs up if changes are just cosmetic and the negatives remain?
Hi Alistair
I've been a huge fan of Agilent/HP gear my entire life, so I'd be foolish to admit that the name doesn't add some personal value for me, so the name will always add some (small) weight to any of my conclusions. As would a Fluke or some other name I am familiar with.
And in practice the name does actually have some tangible value too, in regards to actual circuit design performance and confidence, component purchasing quality, testing etc. Would I trust an Agilent meter more than a no-name meter with the same specs, you bet I would, by an order of magnitude!
Do I concentrate too much on the name? well, I don't think so, I'm reviewing an Agilent meter, not just a Brand X meter, so the name has a lot to do with what I expect, how I think, my previous brand experinence etc. So I find it natural to incorporate that feeling into my reviews. And judging by the responses to my reviews on YouTube and my EEVblog foum, that's what the people expect of my reviews.
Regards
Dave.
Hi Ghamble
The outdoor performance is not actually diappointing when you take into account this meter is not designed for outdoor use, and Agilent say this in their promotional blurb.
Quote:
"On the go or on the bench, you’ll get crystal-clear viewing indoors, even in dark, off-angle situations."
If you need an outdoors display you can buy the exact same U1252A meter which has an LCD display and longer battery life.
Some people have unfairly focussed on this meter saying it's a terrible design because of the screen. But if you think about it, it's not terrible, just different to the usual LCD offerings.
Yes, the battery choice is poor, but realistically few poeple would use this meter continously for 8 hours in a day, and you can get more battery life using a Lithium or Alkaline primary if you use it intermittently.
The battery consumption is actually on par with the competing Fluke 289, when you take into acccount the screen and battery type. So it's not as bad as it seems.
As to the solderng quality I believe I am judging Agilent fairly based on my experience. Agilent make first quality products, and I firmly believe that what I saw was a-typical. I would not think that was a-typical if the meter was a no-namer.
Regards
Dave.
Thanks for that Dave,
I can see where you are coming from. It's just my opinion that things do change over time, and the market leaders need to stay at the top of their game to keep and improve their market share and profits. There are a bunch of no name manufacturers that are up and coming and Agilent has to see them as a challenge, because one day they will have a name if they can keep up quality and keep down costs.
Showing my age now, but I remember in the 70s when made in Japan, or made in Hong Kong was another way of saying cheap and shoddy. Now our AV equipment, vehicles, white goods etc etc are almost all manufactured in these areas. When I was looking for a new TV recently I read a lot of magazines on equipment, and the highest rated 32" LCD TV was a Samsung. Who'd have thought 20 - 30 years ago that a Korean manufacturer would be the best quality TV manufacturer in the world, and the old western quality TV makers like Pye and Ferguson are defunct?
