content: My first digital multi meter was a $20 locally manufactured DMM and worked fine. Thinking it was faulty bought UNI-T 61E with more features than the $20 meter of course.Some modifications for th UTI-61E model are available on Youtube but I am happy with it the way it is out of the box and I find nothing to fault with it and even though this model did not have problems reported in Youtube videos I found no need to make any changes.One interesting thing I did learn about when checking my meter for making any possible modifications is there is a tiny and fragile ribbon wrapped around the readout screen. Reassembling the meter and not putting the ribbon into the meter correctly gave me erratic readouts.Interesting that.

content: Here in the colonies, I can get a multimeter for free with coupon at a store called Harbor Fright. It will make a Brymen user’s skin crawl, but it works for the most basic things like checking low DC voltage or super basic ohm continuity checks.

content: Hi Zard.Welcome to the forum. If you are not going to measure mains voltage, then almost anything will do.The Aneng dmms are popular, been meaning to get one myself.UniT brand is variable, some models are good but some are bad. The UT61e as mentioned is good value considering its resolution but again not considered safe for live mains (especially if it has been modified). The UT139 is considered safe for mains.Brymen is a good brand if you can find themIf you get used from ebay, any Fluke is good but you will find it hard to get one for £50.Why are some dmms not safe for mains? Dmms now have a rating called CAT, this rating tells you to what voltage and indirectly power the dmm will protect the user if there is a power surge. Power surges can blow components in the dmm and the blast can injure you, see Dave's video where he blows up dmms.Hope this helps.

content: I might as well give my +1 for those meters. They do come in a few different flavours and brands. The one I have is Zotek ZT102, only a 6000 count but for €12 great value for money.I wouldn't recommend using them for high voltages, since they basically have no input protection.

content: Quote from: Zard on December 05, 2018, 09:16:54 amI have an 8008 and 8009 that I keep in my company van. They will never see mains voltage, nor do I necessarily encourage you to try it. They are not bad for the money. I needed small size and accurate low resistance measurements and both deliver on that account. The 8009 is off on DC voltages when checked with my DMM Check + but I won't be using it for that. The 8008 that is a spare if I lose the 8009 is much more accurate on DC voltages. There are also modifications on the net for the Aneng meters that makes the readings more stable if you can do some basic SMD soldering. At the end of the day, they are cheap meters and as long as you remember that and the limitations, they do work. Honestly though, I am thinking of replacing the 8009 with a Fluke 101. They are $40 USD on Amazon here in the colonies. The Zotek ZT109 is a copy of the Aneng or maybe the other way around, not sure which.

content: The issue of which meter is usually discussed in terms of CAT ratings and whether they are believable. CAT ratings are related to how much of a transient the meter can survive without killing the user. So, if you buy a cheap meter, don't believe the CAT ratings and don't work on mains.https://content.fluke.com/promotions/promo-dmm/0518-dmm-campaign/dmm/fluke_dmm-chfr/files/safetyguidelines.pdfAt some point the argument gets a little silly if all you want to do is play around with electronics on your bench.BTW: I would have a VERY short list of manufacturers if I really cared about believable CAT ratings. It would start and probably end with Fluke. I know Fluke in the same way I know Tektronix. Everything else is something less.The Aneng 8008 is a nice little meter. I have one that I use in preference to a couple of Brymens, a Fluke 189 (nice meter) and a Vichy clone of the 189. It's just a handy little meter and very accurate.Not a low cost source, you can do better elsewhere:https://www.amazon.com/Multimeter-Backlight-Resistance-Frequency-Capacitance/dp/B0744MPDJHDave's video:Don't believe the CAT ratings!

content: I just recently buyed the Fluke 17B+, the Aneng 8008, and a "AD584 4 Channel 2.5V/7.5V/5V/10V High Precision Voltage Reference Module". Everything great for the price. The Fluke is a safe multimeter, and it works very well, and can measure low currents, something that the 11x series lack. The 17B+ also has backlight, MIN/MAX, and HOLD. The Aneng isn't safe to measure mains voltage, but it has True RMS, and a lot of counts. I did a quick check with the voltage reference, and they seem to be quite precise. Both of them look like very good instruments for electronics, specially for the price.Check Dave's video on the Anengs. He also reviewed the previous model of the Fluke, but the newer + model has very interesting improvements. That's an opportunity to make a new video, Dave!!

content: Quote from: rstofer on December 05, 2018, 03:30:39 pmThe flip side of that is that I would almost never recommend a fluke for an electronics hobbyist on a budget. Their less expensive meters are really only intended for electrical use and don't have the range, resolution, and features of even inexpensive electronics grade meters. Also remember that CATII ratings are by definition considered appropriate for measuring standard wall outlets or mains powered appliances connected to them. So an off brand meter with a CAT III/1000V rating might be not something I would really trust for measuring a 480 V distribution panel, but assuming it wasn't total garbage I wouldn't really hesitate to occasionally use it for measuring an appliance plugged into my bench. Certainly I wouldn't have a problem using a brymen, extech, amprobe or other well known but second tier manufacturer in such an application. On the other hand, in the few cases where I have measured voltages in a breaker box or distribution transformer, I reach for a fluke every time even though I fully trust a keysight meter's ratings.

content: QuoteIf you are working on high voltages, yeah. Arc blast can hurt or kill you.At household mains outlet, on the safe end of the circuit breaker, a crappo meter that fails isn't likely to hurt you unless you decided to take a nap while a fire started. Even on the wrong side, well, sure... lightning can strike out of the blue. Or the power grid can choose that moment to explode.Hobbyist not necessarily concerned with rewiring their distribution panel or whatnot. A lot of hobbyists will call a qualified electrician for stuff like that. I think $50.00 is overkill for a first DMM. I have been using DMM for decades, and I never spent more than 25 dollars.

content: Quote from: rstofer on December 05, 2018, 03:30:39 pmIt's simple, if it has been independently UL or ETL tested then you can be confident in it. All the major brands have meters (sometimes not all models) with this. Even Uni-T now have some UL listed meters.Some like the Japanese companies like Sanwa do internal qualification to the same standard and can be trusted.

content: I don't think typical hobbyist is interested in mains voltage at all. I have tested and played with AC voltage using Aneng 8009 meter and it was fine, I don't know how to test it for this purpose.As Dave stated, it is the perfect choice for a beginner. Next, you could buy eevblog custom meter as it seems a true upgrade in all shapes and forms of the word... I didn't get one yet.

content: Buying an expensive multi meter can be a bargin of sorts if you consider it, in the long run, an investment. For any hobbyist start with the the cheapest thing because you will probability destroy it after just a experiments.

content: Quote from: VEGETA on December 06, 2018, 09:40:12 amAlmost every beginner who gets a scope wants to "look at the mains waveform" as the first thing out of the box. Don't ask me why. I assume when they get a meter that's the first thing they do, they jam the leads into the wall.

content: Quote from: In Vacuo Veritas on December 06, 2018, 04:33:34 pmI think you're right. It's an immediate source of a sine wave (more or less) and the value should be pretty well known.Threads start up here all the time about testing mains with some piece of new test equipment.I maintain that using a DMM on mains is a waste of digits. A solenoid style tester is my favorite because I just need to know the order of magnitude of the voltage (120,{208-240-277},480) and, since there isn't anything I can do about the 3rd decimal place of line voltage, there really isn't much point in measuring it. The voltage is either present and in one of those 3 bins or it isn't.You can tell the voltage level with a solenoid style tester by how hard it jumps in your hand and how much it vibrates. Also by the arc when you remove a probe. This is close enough! With this style tester, I don't have to take my eyes off the probes (and what I'm probing) just to hang by my knees trying to read the DMM.Maybe I spent too much time working on industrial automation. Way back when... Side issue: My issued Simpson 260 circa 1969 didn't even have a CAT rating, yet I'm still here!https://www.amazon.com/Knopp-K-60-Cat-Number-14460/dp/B003A7T5KG
