content: PCB looks a bit Aneng-ish inside but it's all bigger (fuses, rubberized case, 9v battery). A bit sad we've come to comparing something at $9 with what Dave reviewed in #1007 at $25. At least his finger pokes won't tip this one over so easy?*edit - Joe's testshows this bag of bolts is a dud. Better form factor than Aneng mini DMM, a nice try but no cigar..

content: It looks relatively good for a cheap meter - though it does not look like the CAT rating is correct. More like 300 V CAT 2 or similar. Maybe there is a similar EU version with correct labeling.At < $10 it is a surprise to see a labeled HRC fuse - though having a label does not say that much. Still better than the usual 5x20 glass fuse found in cheap meters, though the distances around the fuse holder are still a little small.

content: Good that they marked the 6x32 fuse as 250v on the PCB, if they'd just do that on the front I'd be happier, the fat 10A fuse is an interesting choice in such a cheap meter... I'd say that fuse is probably the most expensive part of the entire assembly, at least retail pricing, for a cheap meter like this, I think that using 5x20 250v ceramics is fine and cheap, as long as they would just mark on the front "250v" for the current ranges (as some cheap meters do, the Mastech MS8233E and rebadges thereof).The plastic looks extremely cheap and shiny in the video. Not sold on that reflective labelling. It gives me the impression of a child's toy from the 80s.

The free ones from HF have no trouble with this but so far every Aneng meter I have looked at was damaged by this. Crack open the fuses. Filled?

content: This meters face plate is exactly the same as my $13.00 “Ragu 17B”, except mine does not have the temp feature, and my rubber boot cover is red. I would never need the amp setting, bought it to leave in road trailer, reading 1800 amp AC tractor generator. Just need to monitor volts and hertz. For $9, I’ll get this one as backup. I lost my 1st Ragu when I tried to make a 9v battery eliminator, and screwed something up, my bad, but at these prices they are practically disposable, and if stolen or broken, it won’t make you cry like losing a fluke.

content: Quote from: Cliff Matthews on July 05, 2018, 03:29:19 pmI've seen a few meters where they route more than the current through the fuse. The problem I see with them is you may not be aware that you damaged the fuse and the meter reads zero volts. You may not have a fuse on-hand and cram some wire in there instead, then go to use the current.We talk with the insurance company today. So far, I have no plans to file a claim as I suspect I can repair the big ticket items but I do want to make sure that if the lab were lost that it would be covered. Interesting thing I did find out is that if the items were damaged by what they call a surge is they limit the electronics. If it was damaged from lightning, there is no limit. But in many cases a surge is caused by lightning.I do like the camera Dave shows. I don't have a device in the house that will display 4K but the quality of the picture is impressive.

Looks like he was doing a plumbing project.Overall, I thought he did a fine job with the video. I didn't see any major problems like I was expecting. The only things I saw the could have been improved were:Spends a fair amount of time mentioning that he is not going to show how to use it but he proceeds to do a fair job of it.At 10:13, talks about current but there is no need to have a closed circuit to detect the voltage. Just may not have a firm understanding of the terms.He does mention early on and then later the CAT III and CAT IV 600V rating. Does not seem concerned if it actually meets it or not.At 11:57, mentions the "MHz one" where it's Hz. I wonder if it will read into the MHz.I'm not sure why he wouldn't just say Fluke has a 17B+ model.I watched a few of his other reviews and get the feeling he endorses everything he reviews even if he has little knowledge of the items. For example:Personally, I like the reviews where people actually put the products through their paces, then tell me what the pros and cons are.

He talked about being an automotive AC specialist or something like that. I was not expecting him to have a solid understanding of the product from an electronics perspective or have a knowledge of the CAT ratings and what to look for. If he wants to continue to receive free goods, I don't think he can afford to make bad reviews.I get comments about my videos being pedantic. Based on the view metrics, I think the sweet spot is 7 or 8 minutes. Exceed that and people stop watching. Good thing I am not in it for the money or fame. lol.

content: @JoeYour videos are obviously very specialized. And you fast forward for us when cycling through to recheck a meter after every potentially destructive test. Most online videos of any subject are just way too long. I suspect the main reason besides filmmaking ignorance, is the extra time and effort to EDIT them properly. And yes, experienced filmmakers can fall in love with their work, and not edit them down enough. Example:When Marty Scorsese was hired to direct “The Wolf of Wall Street”, the contract stated the movie could NOT run over 3 hours. So Marty made it 2 hours, and 59 minutes! Decent movie, but most critics agree about 30 minutes too long.

content: Quote from: joeqsmith on July 06, 2018, 08:24:54 pmYup, I definitely agree with that. I also prefer it if the results and conclusions of testing are in the video description along with any other technical info that might be interesting, keeping the video itself to the highlights: illustrating the test setup, showing the test procedure and so on. Videos are good for showing pictures and illustrations of things that are hard to describe in words, but text is better where words suffice.

After editing, I have my wife watch and if she falls asleep, I cut more out.Making the videos has been a good learning experience for me. I cringe at the early ones I made. I'm not a natural showman by any means.Quote from: IanB on July 06, 2018, 09:08:35 pmI keep the data in a spreadsheet for just that reason. There is really no need to even watch any of my videos. Just download the latest spreadsheet. What's a bit strange is I will have people write me and ask, so what do you think about such and such a meter. More often than not, it's not one that I have ran. So even with the spreadsheet, it's apparently too much to effort to read. Feedback where people want to be spoon fed and then demand I wipe their asses is common. As much as I seem to do wrong, it amazes me that it continues to grow.

However, since the front of the meter says that it's fused for 600mA, I suppose it's kind of moot. Otherwise, I don't see a safety issue, per se. The BM235's HRC fuse is otherwise much better than the hollow, mystery fuse that was included.

content: Quote from: bitseeker on July 09, 2018, 05:27:06 amThanks, that’s kind of what I was thinking. I installed the 400 mA fuse and using the 1 mA current test on the DMMCHECK Plus, and got a reading of only .33, that’s LOW. Just in case, today I have access to my Ragu meter, and it has the identical fuse (500 mA, 250v), put that in the meter, same LOW reading. My other meters read the correct 1 mA, so I suspect something is bad in this meter besides just the fuse, in the regards to the low current test circuit.I could return it, but it’s only $9, and all other functions test properly. Since it can still accurately read volts, and hertz, my main use for this meter, I think rather then use the “under rated” BM235 fuse, I simply will NOT use any small fuse at all, and make a label on the meter, no one will be using this other then me, as it will be wall mounted inside a truck.I’m assuming there is no apparent safety or functionality issues with leaving the small internal fuse holder unpopulated?

Nothing I could do except order a replacement.I think its because the voltage rating is so low and they are not needing a safety fuse for an uncertified meter. I tried to get Fungus to have a look inside of that cheap meter he picked up but I don't think he ever did. At least with the free HF meters, you know there is no fuse on the high current and the worst possible fuse on the low current.

If indeed the fuse is used for all of the functions, I may just jump it to run the normal tests. Or maybe just give into the fact it will fail like any $10 meter and try to improve it.I have not had it out of the bag but it does look very nice for $10.

content: Quote from: joeqsmith on July 12, 2018, 03:30:40 amAll the functions seem to work without the 500 mA fuse NOT in place other then being able to test current in the mA range. I did try both my BM235 400 mA fuse as well as swapping the same fuse from the Ragu meter which is basically the identical meter, with no temperature reading function. But since I’m getting a low inaccurate reading, I must assume that the one I received was damaged somehow and the bad fuse was just the indication. Not worth bothering to return it, as long as the rest of the functions work properly, and in all my tests on the DMMCHECK Plus tester, the readings are very accurate and within specs.

content: Quote from: MacMeter on July 12, 2018, 04:35:51 amNormally, the free HF meters are fairly accurate. The last one I showed was off a fair amount but it's the new cheaper style with no adjustment pot. I don't think I have ever seen a meter that was not accurate out of the box. Sure, they may not power up...Good to know about the fuse. I am confident the meter with the single PTC and clamp with no other limiting devices will do poorly like every ANENG meter I have looked at. This meter has a lot of room so really there was no excuse.

content: Hey Joe, could you add a "tip-over usability comparison" between this meter and the small Aneng to your test? I recall Dave was not impressed with the AN8008 asit fell over every time his hand touched it.Since this meter is sold under several brand names, availability shouldn't be a problem and when Dave does another episode of "How To Setup An Electronics Lab For $300", I think swapping this meter for the UT136b ($25) may be a good choice.""IMHO, the entry point may now be $250 with an RDtech bench supply, the newer soldering irons, signal gens and portable o-scope's. (edit: There's been much competition in 18-month's)

content: Problem I find with many cheap autorangers is that they produce a series of false readings before settling on the right one. Many of the false readings look believable which causes a lot of consternation and wasted time. Thus on a cheap meter I'd generally prefer manual range setting.-How well does this one do in that respect?

content: Quote from: joeqsmith on July 12, 2018, 11:41:21 amYou seem to have been lucky with the HF meters. I had 2 of them that I once brought to a training session. I had to measure a resistance in the 25-30R range for verification of correct part install. Both meters read into the hundreds of Ohms. I had to use someone else's meter to check. I now have an Aneng AN-8008 and 8009, the 8009 is in my toolbag and the 8008 is a backup kept in my company van. I have them as size is a big consideration. Both measure what I need almost equal to my HP-3466A meters. And, I haven't even modified them for better accuracy.

When I check them I have been using the fuel I use (VP C16 and methanol). I have not sprayed any with break cleaner. ANENG meters have been the worse for this test. Most meters, even the free HF meter have had no problems with this.Just to clarify, you wrote "dipping your meter" which is obviously not what I wrote or have done in these videos.

content: Hi there.So there will be a test of this meter for robustness ? It will stay at the same level as one of the bigger KaSUNtest / Aneng / Richmeters ( A bunch of brands...) that was bigger KT6000 / ANENG AN860B maybe?Do it survive a controlled pulse from flyswatter? I have a new flyswatter that is rechargeable but has similar voltage (1989 Volts ) as the AA operated.

content: I lost touch if joeqsmith is ranking at different (increasing) levels or just hits them at their fake ratings, overvoltage Cat. xxx test voltages.It looks like the same crappy PCB layout, kindergarden-grade, as all the low cost chinese DMM's have- bad spacings and traces smoke and burn when overvoltages come in.If it isn't arcing to the battery holder, it's arcing on the mile long run up to the PTC, or at the fuse holder clips, or the rotary switch etc.The clamp diodes look better, it's a single TVS on the ANENG 8008/8009 but here it's a 5-diode bridge.I also don't see the discrete ICL8069 Vref IC, so the on-chip one is used and I wonder how it performs.

content: That was fun. I like the "leash" test (how easily the DMM is dragged around or upset by its leads).The AC (and its companion Hz in the same position) mode behavior seems to be a strict interpretation of AC (having no polarity change is DC). I don't recall other meters acting like that. Interesting.The inability for DC mode to measure the DC offset of an AC+DC signal is weird.

I was expecting at least one person to comment on how well that thing would oscillate.Cliff was asking about the tip over and IMO, its pretty subjective to just tip them. What I showed is really what I have happen with the smaller, light weight meters. On the flip side, I would not want to drag the larger/heavier meters into the field.
