If it's made with 1% resistors, even if calibrated dead on for one range, it could be 1% out on others, also, 1 or 2% accuracy is better than you could read on a traditional analog meter, even with a mirror scale

That's why I want to try the ready built unit that uses surface mount components that might be more accurate. Clearly the range resistors on the kit one are not great.

17:30 I noticed you had a Farnell PSU in the background..... The last time I saw these was back in the early 80's in College. I always like them....... If memory serves, the switches on the Farnell don't look right, I remember them being big flat lever ones...... We had 20MHz Hameg and Gould CRO's too.....(Coooo 😏) What an eye opener when I went on to GEC Coventry and everything was either HP or Tektronix or Fluke.....(They had a 4 1/2 digit Fluke push button multimeter.....in 1983 ! ) must have cost a fortune) Nice review by the way Jazzy

The Farnell power supply was bought cheap off eBay and was known to have issues. The original flat rocker switches have been replaced with not very good quality toggle switches which have failed. This power supply will be a project for a future repair video. I don't think I can get the exact original switches but will try and get something similar. HP, Tektronix and Fluke is good stuff but very expensive. Thanks for watching.

It's surprising how "perfectly adequate" most of the really cheap meters are these days. But, I agree that those auto-set meters can be pretty easy to confuse. Even a few quality steps above the one yo uwere messing with.

Yes, very good results for virtually no money. Electronics has advanced so much. I was not impressed with that auto function 'smart meter' at all. Imagine how annoyed you would be if you were trying to measure low level DC voltages and it all of a sudden switched to ohms and started injecting voltage into your circuit. Very bad.

I you did a consistency/endurance- test on these, I bet the conclusion would be that none of them are worth even GBP 5,- 😆 May I suggest that you look at the Uni-T auto-ranging multimeters. 😉 ( Like you say in the video + GBP 25,- is the minimum you want to spent. ) If you select something from their "better" line-up the Uni-T offer excellent value. Fx. Uni-T UT61A, UT61B, UT61C, UT61D & UT61E. ( Different features, Resolution, Precision and RMS frequency response. ) From a value perspective these Uni-T meters performs great and will last +10 times longer than GBP 7,- crap-o-meters from Temu. Btw. I'm an electronics engineer with +30 years of experience as a Pro. I use Hi-end equipment every day. A couple of years ago I bought the Uni-T UT61C as a gift and was impressed with the quality. 👍 ( I'm not sponsored by or affiliated with Uni-T 😂 I just want to save you from wasting GBP 7,- )

This was just an exercise to see if you could get anything really cheap that gave reasonable results, and some of them do. Only useful for some people who are on a very limited budget. I can imagine they will not stand up to constant use. For instance the input sockets are really poor quality. I am aware of the Uni-T meters and know they offer a very good product for the money. We will look at some of those in the future. I have a couple of Datron 1065's that need service and also a Solartron 7150. If I need anything better than that I have friend who has better still. Thanks for your insight and thanks for watching.

best advice i can give from 35 years of experiance , anyone that can , save up for a fluke 17b plus or something of that quality level, youll never regret it. dont get suckered by "features" a classic is if its got transistor hfe test its complete crap! its vital to be able to trust your readings every day, every year and a real point i never see mentioned on youtube ,very relavent for a hobbyist , no matter how many times youve grossly overloaded it you can trust it 100% and also very important pay high for leads , how many times have you had to wiggle the 4mm jacks and dig in hard to a solder joint or copper trace to get a stable reading ? thats the crap leads dance , even the fluke 17b+ comes with cheap nasty leads through many sellers day one reviews are not long term stability reviews

A lot of people can't afford the cost of a Fluke, especially if they are just starting out. This exercise was just to see if really cheap multimeters were any good at all. Even at this very cheap price point they still give reasonable results. I don't recommend any of these meters for mains use because they have little to no protection but for somebody just messing around on a breadboard with low voltage these are fine, until you can afford something better. That was the whole point of this exercise.

I had a bit of a rant because I totally disagree with this kind of stance and I explained why, but now it seems I have to explain further, You take on responsibility to not missinform, look at People's comments, they are encouraged to buy one of these meters now, you chose to demonstrate static basic tests that don't expose why these are a waste of money they don't have, not being able too afford a good one is exactly the reason they need to save up because their purchase has to be a good consistent and trustable one, and last many overloads, the hard truth is.. £60 is the noise floor of meters, I realise the fluke is a big stretch so I revise my stance £60 is roughly the noise floor for meters but there's another choice, and much cheaper analog, it's much easyer to get a good cheap analog

Not a great deal inside most of them to go wrong. Haven't had them long enough to see the problems you've had. Will be interesting to see if they do fail after a year or so. There is nothing you can do with them except maybe clean the rotary switch contacts. You could also check the solder joints on the input sockets in case they have broken and possibly get some better test leads as well. Otherwise I wonder if the main embedded IC under the solder blob is failing. Flukes are nice but I think they are overpriced. Something like a Brymen would be a good alternative to a Fluke. The more expensive Anengs (£20 - £40) are very good and very accurate. Then there's always the Uni-T meters as well. This whole test was just to see if you can get anything reasonable for virtually no money, which you can, but if they start failing after a year, maybe not.
