About single phase and three phase motors troubleshooting, the UA simply performs with an excellent manner. The bright LCD back light offers a significant assistance in the dark engine rooms, the laud beeper is another strong point, which was missing from any DMM up to date.

Tasks like: Shortcut detection, measurement of coils - voltage — current — temperature - capacitor testing, everything is possible with the UA. The new interesting add-on called as high voltage Alert, by setting the trigger voltage value, you can be alerted about over-voltage or spikes. The only missing feature on it, it would be one phase rotation test about finding the correct phase sequence.

Note: I am afraid that I will disappoint the fellow electricians who work exclusively with VFD controllers and variable speed motors. I do not have access in such systems, and I am unable to test the quality of the Low-Pass Filter, or the accuracy of the UA about measuring voltage or current on variable speed motors. I have to admit that the ms function is something that I had never seen before. It measures the active cycle of a wave form in microseconds. I test a common V mains plug and it was 9.

I would think that this is useful more for electronic engineers, and complex designs. The fast measuring rate and those Part — 6 UA — Accuracy? How it feels on common tasks? Easy to use? But I am crazy enough so to try it, even if they use the latest Fluke calibrators, or even offer a calibration report with its UA right from the factory. After the end of my testing cycle, I can only say that I have lost my chance to find something wrong with it, and I ended up with a large smile on my face, even if had lost in this specific challenge.

The UA is a bit faster, and in the ohms range it is a pleasure to watch it. The extra speed has also and one small downside, when you measure mV and the source is not that stable, the digits on the LCD will update in a high rate, which makes it a bit troublesome to watch the readings. Thankfully Agilent added to it one function called as Smooth , it can be automatically or manually activated, and adjusted by the user.

By adjusting the samples to about thirty, I did solve the problem in the specific measurement that I had a problem with. The Fluke 28II haves the same function, but it is a fixed factory preset. Basically this is the key point of the UA, everything is totally customizable. With a minimum of effort you can adjust it so to fit in, in your specific need. In the beginning when I got the unit, and I realized that I had to get in those menus and sub menus, and I started to dislike it.

I am 42 years old, and I do need good quality and easy to use tools. I do not have any more so many free brain cells, as I was had when I was twenty years old, so to memorize all those extras, that Agilent loaded on the UA. And even my vision, had just start to play games on me, about reading tiny letters in close range. I changed my mind about it, as soon I discovered how useful the UA can become with all the extra tweaking.

By thinking the digital menu, as to was another one round range switch, I found my balance, and now I can get in the menu and adjust anything in seconds. The good part of participating in such testing events are that you have the Agilent HH organization on your side, and its like having an endless warranty plan, and so my hands was free about stressing it, with no second thoughts.

And I set it to run for hours on Auto data logging with small intervals like 1—5 seconds, so to be always busy. I repeated those stress tests lots of times, in some of them it was running continuously for 30 hours. In total it did about 14 days of data logging. Back light Durability: The plan was to find out: 1 If the back light circuitry are durable enough? Everything was ok at the first 12 hours, and I let it run for even more.

At about 14 hours in total, the batteries had lost all their charge and the back light was still on, but the LCD digits were fading to the point that you could not see them any more. I turned off the unit, loaded fresh charged batteries, and it booted up ready again for even more action.

The first thing that I did notice on the 28II, was the less bright back light in comparison with the 87V, it looks to have only two LED as display back light, but it does have back light for the key pad.

I love the back light on the key pad 28II : 2. Personally I will give my vote to the bright display and I will move on. One battery set of four alkaline in a year time it is not a big deal. And there is no need to say, that if you get rechargeable batteries, you will be able to do endless Auto Data logging with out thinking about batteries.

On any other mode with an average consumption mA, on another rough calculation it will probably run with NiMH for about hours 13 days. With high quality alkaline the duration in hours will probably increase. Dave L. Jones is master on such calculations I will accept his word as fact, about the average battery life with alkaline.

The main display has nice shaped digits, they are large enough, and you will not have any trouble even by watching them under angle. I hate the LCD displays with the fat bold digits, the UA has elegant fonts and symbols, but I need to nag a bit for the symbols around the range switch I would prefer them to were a bit larger. About the second line with the smaller digits, I like to watch the thermometer in the top of the display. I would probably expand the functionality of it by using my own ingenuity, as personal reminder about getting a hot or cold coffee, according to the weather or season.

Part — 9 UA — Front and back panel I would not change anything on it, or almost. The probe holders at the back works nice, the probes get in the holder with a gentle move, and they stay securely in place. The addition of the hang hole it does help allot too. Easy fuse and battery access, yes it is easy, I just hate the tiny screws on the battery cover.

And if this rubber cover was connected with a rubber ring, I could possibly pass it thru from the IR-USB cable when the slot are in use , and it could stay there secured on the cable, until to finish the job. The body of the DMM it is very well balanced, by having in mind how stably it stays with the tilt stand open.

I do not know how I will feel if I see any damage on the rubber body of this multimeter, caused by a small accident like a burn or damage from a sharp object. My suggestion to Agilent would be to make easily available all the external replacement parts of the UA, in a friendly pricing, so to stop thinking about it. About the key pad, I am a bit skeptical or I worry too much about those symbols on it, and the possibility to fade in long term.

I love to press those buttons!! Part — 10 UA — Testing under extreme temperatures I love my tools and I do babysit them allot, and so I am always careful with them about to not exposing them to extreme temperatures with out a good reason. But because of this review, I took advantage of the hottest summer days in the hart of July in Greece, so to perform the Extreme temperature test.

The plan was to find out what happens with temperatures above the 40C. As soon the internal K probe of the Agilent stabilized in the temperature of Both units were spot on. Other observations from the extreme heat test: No problem with the LCD at such high temperatures, like fading digits, or no digits at all.

The paradox was that at Some others were made 25 years back or more, and I got them at as second hand cheap and still accurate for simple tasks, like those old Fluke bench top A A A. Nice made tools, some of those were made with excellent craftsmanship, but they do not belong in the category of the main tools by having in mind the modern needs of Modern CAT directives, New safety rules, Inverters, square waves, variable speed motors, Pulse With Motors, Duty cycle, and many more demanding measurements, leads the modern technician so to upgrade and select new and modern tools, capable to handle the modern needs.

Excellent tools made by respectable brands, respectable for different reasons, but still respectable at list by me. Conclusion: The UA is an excellent modern multimeter, my answer to the Agilent HH marketing organization would be that yes, the UA it did managed to empresses me, and so I am suggesting the UA for advanced troubleshooting on the field and bench work, it is a features rich DMM at The teardown video of the UA, presented by Dave L.

Jones electronics engineer, and owner of the EEV Blog. The latest firmware 2. Not to say that the easy firmware update method with the use of the IR-USB cable, raises the expectations about adding on the UA even more options in the secondary functions. This is why the active link between us and the manufacturer, it is so important to us. The UA it is a modern tool for experienced technicians and the experienced technicians are few and picky.

We feel good about our investment in tools, when there is proper availability of spare parts, at reasonable prices, and with world wide coverage. Agilent needs only to improve the spare parts sales on their website. With one well organized E-shop, I would have fewer second thoughts about to become an Agilent customer too. I like to thanks the Agilent HH marketing organization, for the opportunity that they offered to me, about reviewing the UA. And I feel wiser all ready.
