One of the best reasons I've heard to use an analog multimeter is when measurements are being made in an extremely cold environment (like outdoors during Canadian winters ;) ). When it's very cold that's when LCD displays start slowing down making it difficult to take measurements and analog displays continue without any noticeable problems. At least that's been my experience.

The exact reason I have one. It is much easier to peak something when you watch a needle peak and not numbers counting. A digital one that shows you some sort of graph will work but a simple analog multimeter is much easier. Same with RF power. Use whatever meter you want but at the end of the day an analog Bird 43 meter is the standard and what you will be judged with.

I work in telecom and carry both a Fluke 177, which gets used the most, and a trusty old Simpson 260. The Fluke DMM is utterly useless when trying to look for cable faults, specifically grounds, on copper cable that has AC power influence on it. The Simpson will show the fault no problem but the Fluke will not due to the interference of the induced AC. Good analog meters still due have a place in this day and age.

I also have to use it to catch quick high voltage pulses when working on an HDSL circuit because the DMM doesn't seem to update quick enough to see them most of the time. Seeing the needle jump to 180VDC is much easier. Accuracy is not part of the equation, visualization is.

Analog for telco field use. The needle movement is a really good indicator of resistance capacitance impedance etc. Most of the time you don't need to look for an actual measure. The needle activity tells you a story about the copper you're dealing with. It is a craft thing. My Simpson will always be my first choice

analog meters are irreplaceable for audio measurement and adjustment, as the needle 'moves less' than a typical digital meter. I use an analog AC millivolt meter when I calibrate tape decks, near impossible to do with a digital meter. Having said that though, for most other measurements, digital is the way to go. But, analog meters do have their preferred uses in certain applications.

I have 6 meters in my workshop but I still use the analog one when testing transistors in audio work. The reason it makes life easier for me just taking a glance at the pointer and see the angle instead of reading the digits in a digital multi meter. Testing resistance with a DMM sometimes will give erratic readings to a pre energized circuit. Even the slightest voltage will disturb the readings and I have to disconnect the particular resistor to get the true reading. Electrolytic capacitors will hold a small voltage even when switched off for a long time.

It's not a matter of which is a better meter, its using the right tool for the job.

It's not because it's better, it's just not cost effective, practical to change the procedures and equipment out and have to retrain and document. You can still buy some really old meters new and their whole market is because procedures and procurement are too hard to change. The above could be a life or death situation, changing everything is risky unless they get something out of it.

Testing pots/varistors/switches for dead (open/short) spots can't really be done with a digital. My most common use is testing throttle position sensors on vehicles. Analog meters make that test stupid easy. Digital meters miss at least 15% due to refresh rate. All I need to see is the needle jump reliably at the same place 3 tests in a row and you're never going to find that with a digital. That's pretty much the only thing I use my old analogs for. Or if the batteries are dead in the digitals and I need a voltage measurement now.

Sure I use DMMs now, but I miss analogs for one reason : when checking an expected voltage, I could register the needle position within a corner of my eye, not having to directly look at the meter, thus knowing whether I've found, say, 12V or not. With DMMs, even with bar graph - you have to look into the display. I find DMMs to be measurement instruments, while analogs are representation instruments.

Exactly the same reason why many cockpit instruments, pressure indicators, etc. use an analog style display. I say analog style, because the displays are purely digital. A lot of the "analog multimeters are better because..." reasons - other than the ones about very niche applications (GHz AC?) for which I'm sure there are niche DMMs available - are similarly not actually about how the multimeter fundamentally functions, but about how the information gets displayed. Swap out the fixed-segment LCDs for a matrix one (given prices, just go full graphical TFT LCD) and now you can display accurate values as well as graphical presentations however you design it - from a classic analog meter look through to a basic and dirty 'oscilloscope' view.

I remember an upright video game, 3 other techs in shop thought roms were bad. 2nd player score was between 1st player and centered high score. Digital meters showed a bang on 12v supply. My analog swung from 12 down to 8v. Confused, i used a scope and saw the short dip to 8v. One leg of brute force power supply filter cap had broken. Currently i see a fluke meter blackout a 4 micro amp signal, and a couple of other digital meters require a little swag to filter out the effects of non 60 hertz signals. But ohms, i still prefer digital.

@dennischertkovsky8871 4 жыл бұрын
Chris Hoppe Yes. It is called a differential voltmeter. There are a couple videos on KZbin demonstrating its use if you search that term. A very sensitive voltmeter (called a null detector) was used to compare the input voltage to a divided-down voltage reference, usually with a 4-6 digit Kelvin-Varley divider. Once you set the divider so that the meter reads zero, you directly read the voltage off of the dials. Tedious, but could offer theoretically infinite input impedance in some ranges because there is no voltage across the meter once it is nulled out. They have only relatively recently been replaced by 8.5 digit multimeters in NIST-type metrology applications. You can still make a measurement this way with a modern voltage reference, KVD, and null detector, but the combined cost might exceed that of a new car.

You cannot beat an analog multimeter for checking small DC motors. Using the ohm Rx1 scale, you can immediately see if the motor has dead spots (shorts and opens) at various angles by how much the meter jumps around. Shoot, you don't even need to turn the motor shaft by hand to check it too as most analog VOMs will spin the motor. Even will tell you if the bearings are binding. To a less extent, peaking or adjusting for a null is a little better on an analog meter. But yes, for every thing else, you cannot beat modern DVM.

The only thing that was better for me was when I repaired TVs and other electronics. The low input impedance often helped me find errors because a fault in the circuit usually made it react in a non-normal way when I measured at that point. It was also easier to just fast glance over and see that "something" is measured. A digital could sometimes be hopeless with the numbers jumping around. Sometimes you dont know if you got contact or not because of the high impedance. The fact that it works without batteries is also a plus as mentioned. Especially if you want to have a multimeter in a place you seldom need it.

Ultimately i think you need to have both types of meters, a DMM thats at 5 1/2 digits or 6 1/2 digits resolution for the quantitative work and an analog meter for troubleshooting circuits and field service. Same with Digital vs Analog o-scopes, there are certain things that each type will do better. Nothing better than an old Tek 2467 for a fast capture or looking at RF. But just the same I love having a digital o-scope with its serial decode and signal analysis functionality

1) No batteries except for resistance. 2) Needle deflection is very intuitive. A quick glance and you know whether you are in the ball park. There is no need to distract your intellect with abstract numbers. This is another reason DMMs emulate needle deflection with bar graphs. 3) Lower input impedance actually is useful for detecting open alternating circuits with substantial capacitive coupling such as electricians might need.

A few days ago i tried to measure supply current of Z-scale train model, and cheap DMM (I realise that advanced models can do that better, but I have only 830-clone, without bargraph) gave something reliable only for stalled motor. While running, an old analog meter gave me not precise, but more adequate information about current. So, one of analog meter advantages - working with noisy signals (If you need an easy averaging, NOT the noise and short spikes detection). But you still have to check everything with scope while troubleshooting power supply issues. And there were combined models, with digital display and analog needle, for those who have not decided yet. :) (Sorry for mistakes, english is not my native language)

At 12:44 your point about DC input resistance, re circuit loading is well taken & understood. No debate. HOWEVER I have a Triplett 603 analog multimeter that specs out at 11 Meg Ohms DC input resistance and 10 Meg Ohms AC. Yes I also own several DMM too.

In transistor testing digital multimeter can only identify the base the collector and emitter cannot be identified even if its in diode testing or ohms function. The Analog Multimeter can identify the emitter, collector and base respectively. Also Analog multimeter even without batteries you can test voltage AC and DC if you ran out of battery. So its handy to have both analog and digital if you are a hobbyist. Of course nothing beats the digital multimeter nowadays because of functions are being squeezed in these multimeters. Like the Fluke you can have a full featured multimeter. With accessories you can have temperature and the clamp accessory you can have the non contact clamp function.

The one thing that, was good in the analogs was that they were not thrown off by RF. In the shipyard I worked at, we would often take readings in the combat information center and other places on the ships with a lot of RF radiation, and the digital meters would be showing all kinds of readings. You could just wave the leads in the air there, and you would be getting ghost readings. The old analogs were not influenced by this. But other than that, like you say, it is much easier to read and more convenient. The only other thing I like with my old analog would be when I am repairing small electrical tools, and I could put it on the ohms scale and keep it there, since the only time the analog meter would use it’s battery power was when you were taking the reading checking switches and continuity of power cords and such. Saved me a lot of turning the digital on and off, even though they don’t draw a bunch of power just displaying . But these are now trivial things.

The 'fluctuation' thing isn't, or isn't in my opinion, what is demonstrated here. It's actually the analogue meters ability to show readings quickly out of the corner of your eye. As in, when you are quickly dabbing circuits to trace voltage paths, you can concentrate on the test points without having to really look at the meter reading, as experience tells you where abouts the needle should be on the scale. On a digital readout you need to pointedly look at the display to see the reading. Although I do concede this is just about the only advantage analogues have, but then generally it's only relevant for service work on old TV's and radio's. Back then the veteran service hack would have all the readings for the typical sets arriving on the bench, stored in his head, so as long as his AVO had the needle in the general vicinity thats all that was needed. Which brings me to the MAJOR point here, Dave, you haven't lived until you've seen and used an AVO 8. Someone send him one please, for a strip and tell vid! The AVO was a system meter with a huge array of accessories, like range extenders (upto 1000 amps I believe!!) for amps, volts and resistance, even a 25KV probe! Overload protection was provided by an inertia cutout, which basically isolated the meter when the needle hit the end stop with more than a preset force! They are wonderful things, I have quite a collection of them with accessories, leather cases etc. Still use one to work on vintage stuff.

A person working on a factory shop floor can see the condition of a meter from across the room and immediately notice its trending. You cannot do this with digital and has nothing to do with resolution.

Each and evry magnetic measuring head is most accurate at 2/3 traveling distanse of the needle. So even with the most accurate measuring head, your instrument is as good as there are many overlaping ranges, so that you can put measured value around these 2/3-rds. Still, for max-ing and tunning something you have to turn with screwdriver or turn-knob it is the best.

I've got many digital meters, but my go to troubleshooting device is the good old Simpson 260. It has been for 35 years and always will be. The analog meter gives at a glance indications of capacitor charge ability, speaker resistance, transients, and transistor/capacitor leakage. I guess if you're an engineer the digital meter would be all you'd need. Techs have to fix things quickly in order to make any money at all. None of this spend days and weeks determining you've got a leaky part rubbish. You have to fix the product yesterday. And who can read the tiny symbols on those meters. My Fluke has the k and ohm symbols so small I have to put magnifiers on and point a flashlight at it to tell the difference.

Meratronik V640 has 100Mohm input impedance,uses Jfet-based amplifier. It can measure signals up to 1GHz.Max measureable resistance is 10000 Mohm. However I would like to input some more data here. Last year I was doing measurements in my university, an excersise was setup for comparion of multimeters. Two digital multimeters(one TrueRMS,one average), one analog (IIRC Sanwa YX360TRF). On low frequencies the digital ones were winning. The first to fall was TrueRMS meter, autorange was unable to keep up with frequency(jumping between ranges), second to fall was the standard digital meter. Analog was getting bit off but still within few % until the highest frequencies (10+MHz). TrueRMS was falling because ADC was not fast enough, Standard Digital started to fall when analog front-end started to be unable to keep up. In Analog meter it was all about parasitic inductance and capacitance.Also there are analog meters doing TrueRMS too,they require a tons of power from source (which is why they are usually used in industry) but can do both AC and DC trueRMS. I still use my 1970 Mera UM3a analog multimeter everyday, 1% precision for DC,1.5% for AC (metal oxide full wave rectifier). The ability to run without the battery is great, saved me many times, especially when batteries ran out and the shops were closed(eg.national holiday or late hours).

What about reading possible defective potentiometers and rheostat's. In the Navy we had to keep old Simpson 260s analog meters on hand just for those test. They would help detect burn spots/worn carbon traces as the contacts would slide over the range of the potentiometer/Rheostats.

For my first 10 years I used analog meters and I did feel a little 'detached' from circuits when I started switching to digital meters. The feel you get when using an analog meter is not available on digital meters. A bit like getting a car with power steering. Yes digital meters are mostly more accurate but how many people need the 7th digit of their 7 digit meter (or even the 3rd digit)? A great deal of meter work does not need high degrees of accuracy and analog meter 'feedback' is much better and can be an advantage for some uses. Simply focusing on accuracy may be a little misleading. I have to confess that I now only use analog meters when repairing old valve equipment but they are better for some limited purposes.

I don't use them myself for everyday measurements but they can have their use on things such as Variacs and panel mounted stuff so that you don't always need to be down another meter.

I used them for that very purpose for many years and could even see if there was excess ripple. I did say they were not as accurate as many digital meters but even a digital meter needs to be used with caution with regards to accuracy. Just because a meter reads 5.25237856 volts does not mean that the voltage is 5.25237856 volts. Digital meters have a 'needle width'. However, as I said in my original comment I rarely use analog meters any more but I would still recommend anyone wanting to get into electronics to get one and use it for a while for the same reason I would also recommend getting an analog scope. Build a ramp generator circuit at 0.5Hz and watch a digital meter compared to an analog one. This is not really what I would describe as a niche purpose so much as a useful visual aid to learning electronics.

TubiCal, I have been an embedded systems designer for 35 years and my company develops high precision instrumentation and RF equipment and as I said I mostly use DMM's and in fact I need 7 digits for our precision designs but my point is that for a huge amount of work an analog meter will work but my main point is that they are a very useful learning tool. Actually many MCU's don't care if they are running at 3.5 or 5V. It is only when you start getting into the lower voltage units that it becomes more important. I have even pointed out in previous video's that when taking accurate measurements there are other things to be taken into account such as thermocouple contact errors etc and as many people do not take this into account you can assume that they are not reaching the full potential of highly accurate DMM's. If I saw a 40v error on tube plates then I would look for the fault. Why not have a go at aligning an FM discriminator using a DMM compared to an analog meter and you will see the point.

It sounds like the no energy requirement for volts/amps could be useful till this day. Also, maybe if you were planning for the end of the world you would want one of these instead of a DMM? For me though, just having a digital display is so much easier and quicker than having to read it and pay attention to which scale you're on and where you are supposed to be relative to that scale. Similar to a mechanical watch vs a digital display watch. It's just quicker and easier to read out the numbers as they appear rather than calculating it based on distance traveled.

I'd like to add another huge unexpected con of most digital meters: aliasing For example, we use a Fluke 8840A (bench meter) in the lab where we design power converters among other stuff. When measuring a DC voltage in a DC-AC inverter, it often has a superimposed 50Hz ripple. It's not unusual to have some 200mV of ripple while measuring a 1.5V thing. And I've seen the Fluke give a very repeatable reading a dozen times a second, but it sllloowly drifts around the correct value. I guess that it samples in sync with the AC grid, and as the inverter's frequency might be 50.05Hz vs the grid's 50Hz, the aliasing produces a DC error that drifts in 0.05Hz intervals. Which also means that you can have a quite ripply DC supply , and when you check the stability using a good bench meter, you get a deceptively satisfying stable digital reading at a very wrong DC level. I rarely use analog meters, they are inaccurate, but they double as a low-freq oscilloscope when you don't think you need one. Otherwise, it's always better to use a digital meter with an analog readout, but it's very important to have an in-depth understanding of the possible quirks of the equipment you're using.

another application where an analog would work better is if you have a circuit that moves the analog scale in a specific, unique pattern (like slowly up half scale, a little down, then up all the way, and then slowly back down), that is easy to visually remember. And then it becomes very easy to test another circuit of that kind, because human visual memory is very good.

Analog meters have a very nice feature I am using very often. Using a white board marker you can annotate something, i.e. idle current or maximum current. You can use different colors for it and in a split second you know what is going on. Take a look of current consumption of a SBC. You can clearly see if it is running on idle or with maximum power. kzbin.info/www/bejne/bnjZi5SXhc5-jaM The same while tweaking something. Quick look and you can judge how much something changed. When you see two numbers like 2.963 and 2.896 it is harder to figure out how much they differ. Of course you can also use fine point pen, like permanent ones. Looks better but it requires alcohol to be erased.

Dave thx for sharing. Yep I know this is an ancient video but it's something I'm passionate about. What I have seen is that the specs for most digital MMs can't support the resolution they have. Even a lowly 3.5 digit DMM needs to have an accuracy of 0.05% scaling resistors. The specs call out accuracies of 1% or maybe even 0.5%. Clearly these accuracies do not do the digital A/D justice. Now lets move up to a 20000 count or 4.5 digit DMM they require scaling resistors with at least a 0.005% accuracy. when was the last time outside of FLUKE did you ever see even a 20,000 count DMM with a stated accuracy of 0.005%, like never. Don't forget that the scaling resistors should be 4-10 times tighter tolerance than the reporting device. This is just good metrological practice. Dave the A/D in your DMM has a resolution of 1 part in 50K which results in a maximum accuracy of 0.002%. I can only assume your DMM has 0.0002% scaling resistors in it to take full advantage of that 50K count A/D +/- 1 count. Don't get me wrong I'm only citing FLKUE DMMs because I have more familiarity with their specs. There are a few others that are in that accuracy range too, but not many. So, be careful don't confuse resolution with accuracy. I found that you can typically read an analog meter to around, like you said Dave, about 1 part in 250 or 0.4% which is as good as most 3.5 digit DMMs again outside of John FLUKEs DMMs. So as usual we're stuck with either affordable crap or industrial super price DMMs with nothing in between. Now if the DMM mfrs would use full resolution scaling resistors to fully support these high count A/Ds that would be a great move, but sadly they don't. This is why you pay extra for a FLUKE DMM. I think that sums it up. Thx for reading to the end.

For radio and audio electronics I keep a Simpson like that. When you are trying to peak something you aren't looking at a number value so much as the movement of the meter. You are looking for where the needle peaks then starts dropping off. You can do it with a digital but it's a pain unless the display has a graph of some sort. Also when it comes to RF power measurement you can use whatever you like on the bench but at the end of the day the standard accepted gospel and what your work will be judged by is the Bird 43 analog (unpowered unless it has a peak kit) watt meter. I have many digital meters that have many awesome features but my old analog will always have a place on the bench.

I own about 5 high end digital multimeters, including one of yours. I also own about 10 VTVM and analog multimeters. I reach for the analog meters every chance I have where the analog will suffice. The only time digital is required in my shop, ever, is maybe an LCR meter for building high precision resistor replacements for, you guessed it, ANALOG VTVM’s. Ha! Required is even a strong word. A needle width in any project I’ve done in 5 years is meaningless. Unless, it’s the swinging needle during a receiver alignment! I’ll take the swinging needle over a bar graph any day of the week. But, man, I love every meter on my bench from Simpson to Fluke, from HP to Heathkit, from Knight to Macromin Electronics, to yup, Brymen. Great video. Quietly, I agree. Digital wins. Mainly.
