Are analog multimeters still of any practical value compared to digital?
Only Dave can ponder that question for a half hour video...

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.
@suzukiman650
@suzukiman650 6 лет назад
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
@holgers5216
@holgers5216 6 лет назад
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.

Its a very useful tool to have. I find there is nothing faster when doing troubleshooting. I set the meter where I can have it in my peripheral vision when I'm poking around taking rough measurements. Obviously a DMM will be more accurate and have better resolution, I have lots of Flukes. It's not a matter of which is a better meter, its using the right tool for the job.

I think one of the huge benefit of starting with an analogue multimeter - I got my first in 1982 - was it gave you a good grip on measurement error early on: as Dave pointed out, these things are less accurate than their digital counterparts, the resolution was quite low and you'd better be sure you were dead in front of the thing to read it correctly.

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.

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.
@PanoWorks
@PanoWorks 6 лет назад
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.

If you try to measure 10V and the meter rapidly jumps between 9.xx and 10.00 V, makes it look like you have almost 20 V if you don't think hard enough. What could be better than if your altitude appears to be twice as high as it really is? (:

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.

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.

@dennischertkovsky8871
@dennischertkovsky8871 4 года назад
Chris Hoppe Yes. It is called a differential voltmeter. There are a couple videos on RU-vid 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.

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.

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)

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.

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.

I have the Micronta on the left, almost. It's Not labeled "FET Analog" and where the DC10A jack is is an "Output" jack is. I keep it around because it has the fastest most sensitive continuity latching of any of my multimeters. It will detect continuity through 3lbs blocks of steel with oxidized surfaces and it's instant.

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.

Analog meters do a great job of averaging the reading. On some digitals the display is just random numbers making it difficult to see the average.

I have that very same Micronta "Dual Fet" which I use in the field, had it for 20 years, but I also have Triplett 630 NA Type 4 suspension, (pride of place on the desk) it has a doubler, so can get good resolution.. it rarely gets used outdoors tho - so I don't damage it! Just about to order a new 30V battery for it. I've also got a Fluke 77 11 (also has bar graph) to get down to small numbers. All that aside, I really like the Triplett.

you can get a bit of accuracy relative to the circular angle in ohms mode by using the blue scale if i see that correctly. also this removes the need to remember that the 0 is on the other end of the scale

I am a HVAC contractor and for measuring starting amperage for a compressor an analog amprobe is superior, digital does not react quick enough. Although some of the newer digital amprobe (clamp meters) do record inrush amperage.

I use an analog meter mostly for checking transistors for any leakage between the pins in the reverse mode using x1k and sometimes x10k scale. Something you cannot measure with a digital meter on the ohms range and diode test as the voltage is too low.

There is one exception where you might need analog MMs; when the service manual says the measurements was taken with a 20k or 5k input impedance voltmeter, digital ones will read higher values.
@oeioei

With my comment on AC measurements I was referring to the low accuracy at lower ranges because of the voltage drop over the rectifier diodes. Even if the digital meter doesn't have true RMS, it is still superior.

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. On a digital meter it just looks like the meter is normally searching for a value.

That exactly the point ... most of the time precision does not matter but have ability to "see" what is going on is priceless ... Also people more easily remember angle of needle of "safe value" than read value and think if it is OK or not ...

Remember too that the 2% or 1.5% was of the full scale for that range. So care had to be taken to assure that readings were in the upper part of the range to achieve better accuracy. I had forgotten what a pain in the behind analog multimeters were. I was a bigger fan of the VTVM because of input impedance problem

But Dave I still use my analog insulation resistance meter everyday, much easier to find electrical faults over a slow digital type. Especially if the fault is random, you can see the needle fluctuate as the digital types tend to dick around.

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.

You keep saying analog multimeter, but arent these really VOM (Volt/Ohm Meter?) I thought we only started calling them mulitmeters when they went digital, because they do many functions besides just volt/ohm.

@mekatronikorg 6 лет назад
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.

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.

Last time I remember Analogue having the edge over Digital was for multi-track tape recorder alignment. The BIG AVO meter scale was just the thing for tweaking those head positions and peaking/nulling the bias oscillator coil cores. Hi-res, fast refresh bar graphs of this era, but not the 90s DMMs, could get somewhere near that performance I guess but none as big as the old AVO movement. For all that though, even the revival of the tape machine is an old thing now and they are pretty niche, but they're still out there. My old AVO 8 needs a good service. My Mk7 probably needs a nice museum to reside in.... Got 5 DMMs at the moment. 6 when the EEV BM235 arrives 😉

The RCA Senior VoltOhmyst (WV-98C) has an 11 Megohm DC input resistance. I think the Fluke 87 is 10 Megohm. Kind of impressive for an old school analog meter.

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.

I used to use analog meters to find resonant peaks and dips of loudspeaker response by monitoring current drawn from the supply of a small amplifier. Much easier to see than the changing digits. The bar graph was useless for this too (not enough resolution).

Analog meters are a really quick way to test a large capacitor, set on ohms hook up the leads. Meter will show a low ohms reading then as the capacitor charges reading will show up as an increase in ohms, just watch the needle. Works great with the larger capacitors used in the automotive industry, or in heavy equipment
