content: HI all, just wanted to say this is an awesome forum with lots of great info. Been reading through it for the last couple days trying to get up to speed on multimeters.Anyhow I am currently looking at a few models and was wondering what you guys think of them? I will be using them to build and test machinery that uses DC and AC voltages in the 12-400v range. These machines run off VFDs and use AC as well as DC servos/drives. So I'm trying to figure out what multimeter to pick up out of the millions out there.These are the ones I am currently looking at, if you think there is another one feel free to tell me. I am still a newbie when it comes to these devises, but I want something that will grow with me as I get more familiar with them. If there is some feature or spec you think I should stretch out of my budget for feel free to say so as well.The Greenlee is my favorite so far, seems to have solid specs and a nice lifetime warranty.Greenlee DM-810Ahttps://www.amazon.com/gp/product/B003TO5YUA/ref=ask_ql_qh_dp_hzaKlein M700https://www.amazon.com/Klein-Tools-MM700-Auto-Ranging-Multimeter/dp/B018CMKWSC/ref=sr_1_1?ie=UTF8&qid=1512721737&sr=8-1&keywords=klein+mm700Amprobe AM-530

content: Quote from: WesM on December 08, 2017, 08:33:15 amPlease ask Greenlee to show in writing or on their public website specifically what lifetime warranty means. That is, if you own the meter for 15 years and suddenly it dies, do they fix it for free? Is lifetime your lifetime or the meter's lifetime. If the latter, what is the exact number of warranty years?The answer, in the past, given here by others has not been satisfactory to me in terms of how many years. No one, so far, can point to the Greenlee website to show how many exact years.For example, Fluke also specifies lifetime warranty, but in the fine print it specifies a minimum of 10 years. It is right inside the manual with its terms and conditions.The Greenlee 810A is a rebadged Brymen meter. Most Brymen meters have a 1 year warranty.

content: Your application seems above the power levels of the plain hobbyist around here. Both the Greenlee and the Klein seem to be up to par with your application, with a slight edge to the Greenlee due to its input bandwidth of 20kHz for AC measurements (the Klein is only specified to 400Hz).One other brand that has good reputation is Hioki. The model DT4255 ison saleat Tequipment.net, which can bring your price even lower with thediscount for eevblog members.It may be overwhelming, but there is an excellent spreadsheet that lists several brands and models atthis link

content: OK so on warranty I kinda get that some lifetime warranties are better then others. However, Fluke is pretty much the only other multimeter brand (I know of) that offers them, and at very least its hopefully better then the 2-3 year warranties you see on most multimeters? Anyhow in this price range Fluke is offering a 3 year, but this is just quibbles. What I'm after is an American company that sells a product they will support.The Fluke 115 is in the running for me, though it definitely stretches my budget a little. In your guys opinion how does it compare with the Greenlee DM-810A?The specific application I will probably be using this most is designing and building 3-5 axis CNC equipment. Its not necessary that I have the most precise MM, since most of what I will be doing is mechanical design/assembly. I do want something that is safe though, which is kind of why I had zeroed in on the Greenlee/Brymen MM. Most of the flukes are well out of my budget, and I was not sure how the cheaper ones like the 115 would hold up. I will read up on the Hioki though, never heard of them.Just curious, does anyone know what model the 810A is a re-badge of?

content: Quote from: WesM on December 08, 2017, 03:27:53 pmIf you don't need to measure amps then a Fluke 101 is probably plenty of meter for you. They go for $42, delivered. Don't be fooled by the price, they really deliver on safety/robustness.(if you need to measure amps in an industrial setting then a separate clamp is almost always a better choice anyway so you'll still have $60 to get one...)

content: Quote from: mtdoc on December 08, 2017, 04:27:59 pmInteresting; I can't pinpoint which Brymen this Greenlee corresponds to, so I could evaluate its relative price. Perhaps a special run based on the BM827/829 family?Hioki is a long time Japanese manufacturer of test equipment.BTW, if you live close to a Fry's Electronics, you can also check their clearance on Keysight U1231A/1232A/1233A meters - they are being sold at quite reasonable prices and are decent meters.

content: Quote from: WesM on December 08, 2017, 03:27:53 pmI don't think anyone would argue that the Fluke meters are excellent daily workhorses and will give you many years of service with one of the best warranties in the business.But the Fluke 115 is a fairly basic multimeter in terms of functionality. I'm sure it would meet all your needs and be a great meter, but you also mentioned wanting to get into a meter that you could grow into -- so I interpret that as having a meter with a few more bells and whistles.This seems like areally good priceon a new Greenlee DM-810A:http://amzn.to/2BjGfi8I could not find an exact matching Brymen product that matches the Greenlee DM-810A. It almost seems like a Brymen 827s with a reduced set of features and the removal of the CREST (min/max) and REC buttons.I think that the Brymen 827s is the same as the Greenlee DM-820A.The Greenlee DM-810A is giving you a few more features over the Fluke 115 with dedicated milliamp and microamp current ranges, duty cycle, and a higher CAT rating for high voltages. It's a large form factor so take that into consideration if you need to fit in into your toolbox or are looking for a compact meter. The Fluke 115 is a 6000 count meter where the DM-810A is a 10000 count meter, so the DM-810A provides a bit more resolution however I think you said that was not a greatly important for your needs. The DM-810A can also optionally be connected to a computer to log and graph data with an extra accessory USB cable. I don't think the Fluke 115 can be connected to a computer for logging.I really like Brymen/Greenlee meters I own several (I also own a few Flukes, but not the 115). But I really don't like that the 810A is missing the CREST button that gives you MIN and MAX functionality. There are times where this is very helpful for me. So with that in mind, I might consider stretching up to the Greenlee DM-820A. It includes the CREST min/max feature as well as a REC feature. (take a look at the manual to learn more about this feature, it's not full data logging.) The 820A also includes the ability to measure temperature readings. This can come in handy from time to time.Here is a pre-owned Greenlee DM-820A for sale that's not a whole lot more in terms of cost:https://www.ebay.com/itm/Greenlee-DM-820A-True-RMS-Digital-Multimeter-1000-Volt/362115264156?epid=2255478102&hash=item544fc06e9c:g:Cj4AAOSwnTdaHutfYou can can read about some of the differences in the Greenlee 810A/820A/830A manual:http://greenlee.ebizcdn.com/9b91d245c953f54a7f10aba72a4d0022The Greenlee DM-210A is also a nice compact meter and may be more directly comparable to the Fluke 115.http://amzn.to/2BjTsaHFor an everyday field meter, I think I would go with the Fluke 115 or the Greenlee DM-210A just because they are more compact and simple. But if I wanted a tool that offered more features and I did not mind a slightly larger form factor, the Greenlee DM-810/820A would be the way I would go in this price range.See the photo below for a size comparison between the Greenlee DM-8xxA series and the Greenlee DM-2xx series (same as Brymen 2xx(s) series)

content: I decided to pull the plug on the Greenlee DM-810A. Will have to see how it works. I hear ya on the lack of min/max function, but I'm not sure if thats something I will be using with my setups. The electronics lab at work has a few Fluke 87, so I will try and do a little comparison when I get the 810A.Thanks for all the advice! Hopefully I made the right choice

content: Quote from: WesM on December 08, 2017, 09:04:06 pmI don't think you will be unhappy. The Brymen/Greenlee is a great meter.In case you need spare fuses, these have worked great for me:11 AMP (set of 5)http://amzn.to/2B2T4gk440 MILLIAMP (set of 5) -http://amzn.to/2kcTwhBOr a single spare of each in a combo packhttp://amzn.to/2nIJGsKAlso, when and if you want to feel like a multimeter elitist... get yourself a good set of silicone leads such as this Brymen set:https://www.ebay.com/itm/Brymen-Silicone-Gold-Plated-Test-Leads-Probes-for-Multimeters-CAT-IV-1000V/171162377470?epid=2063657290&hash=item27da129cfe:g:uSQAAOxyTjNShpch... or Fluke silicone leads or any other premium brand of leads.After using a premium set .. its hard to go back :-)However, you will be really pissed if you short an arc across your premium leads and disfigure them

content: I have a Brymen 257s which I'm quite happy with; a compact and capable meter. My only criticism would be that the backlight turns off automatically after a frustratingly short period (what is it with this "feature"!?), and that the kick stand is pretty flimsy and unstable. Can't remember what I paid exactly, but it was around the $100 mark.

content: Quote from: Russ on December 09, 2017, 02:29:06 amSadly the Brymen 257s backlight is only lit for around 30 seconds. I don't use the backlight often, but I would agree it would be annoying to turn off after only 30 seconds. Despite this drawback, its a really nice compact meter. This model also supports data logging via a specialized IR-USB cable which is the primary reason I purchased this model over the EEVBlog 235. I did purchase one of the EEVBlog cases and accessories from Dave for my Brymen 257s -- perfect fit and a great addition for my 257s.

content: Quote from: blueskull on December 09, 2017, 03:36:33 amI did look at the BM235 meter. If I was going to jump to the $100-150 meters It would have been between that and the Fluke 115, and honestly the BM235 is a lot more feature rich for a quality meter then the 115. So I probably would have gone with the BM235.

content: Quote from: Russ on December 09, 2017, 03:30:32 amSadly not, unless Brymen were to release a firmware update, along with instructions on how to flash it. Unlikely.Edit:That said, it should be possible to power the backlight LEDs separately - perhaps wiring them up so that they're on whenever the meter is on. This would of course shorten battery life dramatically, but since I use rechargeable batteries and always have charged spares to hand this might not be too bad. Assuming a dozen or so mA draw, battery life should still be many hours. Alternatively, find a way to mount a physical switch for turning the backlight on/off.I really cannot understand what the purpose of "auto off" on the backlight is; if I press the button to turn it on, that means I need the display to be lit - and I am perfectly capable of pressing it again when it is no longer needed.Edit 2:In fact, this is one of the main reasons I'm thinking of getting the new EEVBlog 121GW meter...
