I might be a year late, but man this is probably my favourite multimeter on the channel so far. And the fact that you can have this functionality and build quality for just $30 in the end of 2020 just amazed me. Would definitely buy this one if needed a replacement. There is a RM406A model that apparently measures temperature and has capacitance range up to 100mF but no "high speed measurement" feature. It would have been a tough choice for me for sure. I don't like to leave empty comments. But I'll feed that annoying RU-vid algorithm in hope it'll promote this channel at least to some degree. It deserves much more than 3.5k subscribers.
Definitely 👍 a terrific multimeter and one of my favs on the bench! Its incredibly fast to range as well which is really nice especially when troubleshooting alot of components. Thanks for the kind words...The Channel will only get bigger and better with subscribers like you ! Keep on Testing! 😀👍
Really great to see some of the meter manufacturers giving us even more for our money, starting to see more ten thousand count meters ive noticed - of course the one thing you still wont see for these prices is the input protection of the big boys but these meters arent competing in that group. Many will only use theirs for DIY and home low level-medium input work and used responsibly these are amazingly great value feature rich meters for very little money.
Agreed, lots of meter for little cash. It does alot if not more than meters costing 10x as much. Yes, input protection wise it's no Fluke, but it's also fine for most jobs, if you need to test high mains then you'll probably need to invest a few more $$$. Definitely robust for the DIY or Home Electronics Lab.
Personally, I would rather see a current shunt any day...A current sensing resistor could be used as a cost saving measure or pcb design utilization to save space. The tolerances are usually adequate but temperature coefficients aside I still prefer a big beefy shunt in my multimeters!
Was hoping this tear down will show the rotary switch copper tracks on PCB. I have a Mestek DM100 identical with this one. After approx.14 months of moderate use (few times a week) the multimeter would only display NCV mode no matter the knob position so I concluded the rotary switch developed a serious problem probably from the lots of rotations that have to be done to get to the desired scale. Found the rotary switch tracks on PCB are poorly designed with plated holes right in the middle of the circle shaped contact tracks and so the domes of the contact plates on the knob rub against the plated holes all the time. I love the fast measuring algorithm implemented in this DMM but with a dead one already I will look for other options as its replacement. These days RM406B or DM100 cost around 30 USD on aliexpress still feels expensive if it lasts only a bit over 1 year.
Thanks for the review. I'd almost be tempted to buy one just for the neat display and VFC function. I can forgive no REL function, but how any modern meter, even a cheapo one, can fail at LED testing and 100M resistance is beyond me. Almost any hobbyist is going to want those functions working properly. I'd be interested in hearing what Richmeters says about it. Also, an awful lot of these meters look a lot alike, could they all be made by one or two companies? Possibly Zotek and Owon?
I agree, I will ask them and post the reply. Richmeters is not an OEM, they do not do any R/D far as I know..but I will have more details to follow... Yes, to bad about those led's..dang, that really upset me. Overall though, its a very nice instrument, well made, does not feel cheap and ohhhhh that gorgeous display!
@@KeepOnTesting The display really is great looking...have you taken one out in the sun and seen if it was visible in direct sunlight? The one reverse LCD I got to look at was unusable in direct sunlight. At least half the home repairs I do are either on the car, the evap cooler, the A/C or one of the outdoor lights. That being said, the cost of these meters is so low that I don't really mind having one for indoors and another for outdoors. But it would be nice to know before buying. Review the clamp meter next, please!
@@3rdpig I will try tomorrow outside..overcast the last few days..I will let you know how the display looks! Clamp just arrived so it will be coming out for the review soon!
Nice multimeter but failed the LED test. Obviously probably because it had only 2 x 1.5V batteries. Can you please explain why the LED test is important. Thanks in advance
It's a personal pet peeve for myself, I believe every multimeter should be able to illuminate and display forward bias when testing LEDs. Call it a basic test function that should not be optional as its every basic testing criteria for any dmm.
Im in the market to get my self a multimeter, between RICHMETERS RM406B & UNI-T UT89XD which is more recommended? (Maybe do a comparison review of these two?) Need one mostly for automotive and electronic boards testing, or there is better one you can recommend in same price range. Thanks
Hi Peter, because you've mentioned Automotive repair, I would choose the UNI-T just because it's better built to withstand the rigours of car repair. Also the Bluedriver Multimeter I reviewed last year is another good choice if you will be doing alot of car work. Good idea about the SHOWDOWN comparison, I will keep that in mind.
@@KeepOnTesting, Thanks for reply an recommendation, probably will go with UNI-T one, also I've checked out the BlueDriver Automotive Multimeter and can't find one selling, where they been listed for sale they are out of stock or unavailable.) Comparison videos are great between similar price range and similarities between units and brands.))
Does the NCV mode detect wires behind drywall? (Similar to a stud finder for example or some better quality voltage detector pens) And would it be able to follow a wire along the wall???
Darren Walker i know that’s the concept but most reviews i’ve seen of multimeters with NCV are usually almost worthless, most have a hard time reading a powerbar so i was just wondering how this one fairs on a drywall per say. See like this one seems like it actually has good NCV capabilities ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kxvIAD0zack.html
Could you please make test of NCV, that it is capable to find live wires inside of a wall? I have UNI-T UT171B which works amazing even for not loaded wires and I am looking for some cheap alternative for home usage. It is better than any wire detector I have seen.
@@qolbunsalim5188 Here you go (Sorry for the delay...) Richmeters RM406B battery usage is a whopping 24mA!! Habotest 1.8mA with No backlight. 16mA with Backlight and 24mA (only for 6 seconds) with the input alerts flashing). Hope that helps!!
I feel like im a victim of temperature discrimination-lol-how can such a nicely equipped meter offer something like relative humidity yet read only in C* and no F*-?!? still watching. And ill say it again - clean those probes first, it almost always helps
Thank you-! Really caught me off guard I never win anything-lol Darrens a great guy and makes some of the best meter review videos around for us addicted collectors and others as well -- Thanks Darren-!
@@KeepOnTesting Go for it. I didn´t make reviews or something. From the sideline is always easy to commentary. :) Also a lesson for me: if you give feedback do it the positive way. Mostime i do but i think it wasn´t my day... ;) Really interest. You has reviewed a lot of cheap multimeters. What is in your opinion the best multimeter for price and quality. This Richmeter?
@@KeepOnTesting I tend to find little cheesy sound and video effects kinda amusing, most reviews are dull and boring ... so, I guess it is a matter of opinion.
