From Dave Taylor, former Fluke meter designer on the EEVblog forum: "The 37 form factor was requested by corporate buyers because the small handhelds walked out the door too easily. Specifically it was made bigger to prevent theft."
An alarm clock? Beep, beep, beep.... Oh sh*t, I'm late for work!... Kinda works Beep, beep, beep.... Oh sh*t, better wake up after a Friday 2 hour lunchbreak at the pub, for the 4pm meeting with the boss.... Works much better!
I've had my eye on getting one of these for some time. Just found one on eBay with all accessories, a temp/thermocouple module and the original manual. Went ahead and got it based on this video. Thanks Dave!
Yes, old Zamac zinc aluminium alloy, with the characteristic powder bloom from the reaction with moisture for the untreated alloy. Could do with a clean up with a green Scotchbrite pad, and then 2 coats of clear lacquer to protect it, with only the contacts for the shield connection being left bare, though a thin film of silicone oil will help kep it clean and bright.
@10:15 The small circular looking "clock" in the center. It is a date and mold stamp used for injection molded plastic. The lines are the flow lines emanating from the injection sprues.
Looks like a structural foam molded part to me, not metal. It's plastic molded with a blowing agent that creates gas bubbles inside the part to reduce weight and material use. The parts tend to have a rough surface with highly visible flow lines.
I purchased one from RS in the 80's and it still serves me well today. I have never had a bit of truble with it and never removed the case so interesting video.
I have one of these on my bench at work and love it. Like you said the form factor is exactly right. I am glad I got mine a while off eBay for cheap 'cause now that you did this video the price will skyrocket.
Tektronix did a 851 which was a multimeter on steroids, had a sloping front but was a lot larger, I had one donated by a supporter for me to repair it, which I did manage to do and did a video or two on it.
Yay oldschool meter video! I saw an ad in a 1984 electronics magazine for the Fluke 8025A (on which this is based on) if I remember correctly so.. the design must be from the mid 80's like you said. The little fuse is in series with the one used for the miliamps and microamps and it is rated so it blows first and saves the owner the price of a 1000v hrc rated fuse.. the larger one only blows if the little one can't interrupt the current. Also I think I see two PTC's on the board, just that they are the boxy unpainted type.. one next to the shunts and one on on the other side of the range switch next to some resistors. The form factor is nice and the range switch is awesome on these, well worth the money on ebay. PS: Glad to see the old 27 still in your collection, it's a keeper! Thank's for the video :-)
I use a Fluke 29 as my only multimeter. Only drawback is no temperature probe, and no clamp meter functionality. It has the flexible kickstand! My mother was an engineer at Fluke in the early nineties and got that meter from her employer at a discount for my father. Growing up with access to that meter is likely one of the factors that led to me choosing a career in EE.
I worked in Cal house in the UK last decade. We tore through tons of MOD Fluke 27s in various states of destroyed. The first test we'd do while walking them from the shelf was open circuit conductance (nS) test. It needs to be below 0.10nS (>10 GOhm) and gives an indication of board contamination or blown protection devices.
Got one on the bench here for a decade. It never failed me. I never changed the battery. It’s the optimal size for a portable multimeter. Throw in the probes, screw drivers, cutters and a biscuit and go fix stuff!
The carry compartment is as I see it a quite nice touch - probes and alligator clips would be nice to have there. I'd like a front cover on a hinge too just to protect it during transport - and it can double as a stand.
Radio and Electronics Magazine back in the mid/late seventies ran a project piece with a prototyping workstation that used a sloped-front cabinet very similar to this, without the bail. It had two analog panel meters on the front for voltage and amps, +5/±12V supplies, a bunch of LED indicators and various other accessories around a bank of three prototyping sockets. I've never managed to find the article online, alas.
I got this one specifically for the form factor, cause I wanted a bench multimeter to put on a shelf above my bench and this was pretty much the only one I found for cheap.
13:56 What is the point of connecting FULL bridge rectifier like that? Can some-one write quick explanation or point me to the literature where that is mentioned? -Thanks
Unidirectional directional clamp, with 6 diode drops, but only requiring 8 diodes thanks to the bridge, rather than 12 needed if you just used 2 anti-parallel strings.
For the external power connector you can design a little solar cell with boost circuit. They lacked that idea in these days. The form factor is stable; that Fluke 27 is orientated vertically, and one pull on the leads and it falls.
The Beckman Industrial 360 is another benchtop multimeter with storage compartment built in. It's a 3.5-digit true-RMS multimeter and it even accepts K-type thermocouple probes to measure temperature. The crazy thing about this model is that it takes 6 size D batteries. When I got mine used, the batteries had a date code of sometime in the 90s. They were Duracell batteries over 20 years old with still enough juice to power the multimeter. However, I replaced them anyway with a fresh set of Duracell batteries.
I love those old PCBs with the crinkly tin underneath. Looks just like an 80's GM ECM inside with the square crinkly traces and the old-school components.
interesting form factor... that metal shield almost looks like its galvanized... thanks for the teardown Dave...always good lookin at old gear edit: on closer look and the sound from tapping... seems to be metal impregnated plastic!
@10:15 The small circular looking "clock" in the center. It is a date and mold stamp used for injection molded plastic. The lines are the flow lines emanating from the injection sprues.
@@WacKEDmaN Another clue @10:15 is the brass threaded inserts encased in a large cylindrical boss. If it were thick metal, the metal itself would be threaded or perhaps a brazed/spot-welded on nut. If it were thin metal, it would use sheet metal type screws or screwed with spring steel "U" nut clips.
My favorite Fluke is the 8050A-01, onboard batteries or mains, dB conversion, Mine ( bought new back in the '70s) lost its liquid crystal display and naturally, Fluke has no parts. I have an equally as old 8010, mains only, fewer digits, no dBs, that still works. My overall favorite bench multi is the HP33401A. It lacks histograms and multi-color display of current offerings but it tells the truth and has been reliable for approaching 2 decades.
Regarding the shield it looks like molded plastic with some form of metal filler, probably for conductivity and possibly to also help act as a flame retardant. Can see the lines of flow in the plastic from the molding process. Also the use of brass threaded inserts alludes to it being plastic as well.
Just got a OWON XDM1041 because I like that form factor. It fits perfectly on my bench. This one is 55000 count and mains powered only but then it has a beautiful big colour 3.7" LCD screen. It also got a serial SCPI interface.
@10:15 The small circular looking "clock" in the center. It is a date and mold stamp used for injection molded plastic. The lines are the flow lines emanating from the injection sprues.
I'm guessing it's capping the voltage across the shunt for protection. 4 diodes across the diode bridge act as the "load" in standard bridge terms. In either polarity of applied voltage, the input would see 6 diodes (two conducting in the bridge at a time, plus the four) so it would start conducting and cap the voltage at approximately 0.6 * 6 = 3.6 volts. Don't know why, but they wanted to cap it at specifically 3.6 volts, and the circuit is basically a cost cutting measure (but achieves the exact same) as having two strings of 6 diodes in both directions.
at 14:00 On the Topleft with the 4 Diodes, all Silkscreen symbols point to the left, the bottom Diode is turned around though against the indicated direction. Maybe just a Silkscreen error. Since it worked sofar.
I have two of them. Love them! One has been cut off, with a bandsaw, just behind the front part, so the handle and the compartment is missing. (not by me) Bought them very cheap, 10 € each, on the ETA, Chalmers annual Electro Technic Auction, Gothenburg, Sweden.
Back in the very late 1970s I had a BK Precision LED multimeter that was compact (5x10x12 cm) and portable, but went through batteries very quickly (6AA, IIRC). In the end, a massive leak from all batteries killed it.
Somewhat related... Am I the only one who would love to see a desktop scientific calculator? I only ever see basic desktop calculators -- wouldn't it be nice to have a dedicated desk scientific calculator with large display and buttons. I'm half-tempted to make one, even.
@@EEVblog That inspires me! I'm thinking of using standard keyboard keys (like Cherry MX) on a PCB. The question is whether to use the internals of an existing calculator (perhaps FX-991EX), or do a whole custom job involving a micro-controller.
Can't go wrong with a Fluke meter. The form factor is great for placing the meter such that it is stable (not trying to prop a meter up on its flimsy back leg). Nice classic design to. I think a re-release would be cool. Cheers,
One of the few (maybe only, depending on your definition of "era") meters of that era that I only own one of. Crap, I didn't even realize my stand was missing. I didn't realize the display PCB was different from the 27 as well.
I'm so used to the "John X" format of giving an anonymous personality to a company/group that for a moment I thought you were joking when you read out "John Fluke"!
Almost looks like metal impregnated plastic of some sort, although density must be close to aluminium or Dave would have said something. Might be interesting to see how conductive it is.
@6:49 Look at the exposed edges of the case. Really thick. They wouldn't do that with metal. It's a type of plastic. If you're able to blow it up big you can also see the exposed edges are sawn. ad. Also @8:14 sawn edges.
Got it. @10:15 The small circular looking "clock" in the center. It is a date and mold stamp used for injection molded plastic. The lines are the flow lines emanating from the injection sprues.
My vote is for a new full 3d printed plastic case - and while at it, why not place the fuses on the reverse side to minimize depth. A metal π-shaped adjustable stand would work wonders too. The 90 degree angles on the pcb tracks is huge turn-off though. Probably doesn't matter a bit but it does scream laziness... Or perhaps it is optimal: after all tracks crossing vertically exhibit minimum interference. Are there any tracks crossing vertically, however, that justify this? PS: Having said that, quick ebay.com search (14/5/21) reveals: 161 Fluke 27's and just 2 (!!!) Fluke 37's. I guess there won't be much demand for a third party case. Also, the 27's can be had for the same or less money and some time come with a protective carrier case which a great boon.
@@1978garfield hehe I have cheapies too for when I think they will get damaged. I paid under 40$ each for these meters so Im not too worried about them getting damaged :)
The design of the formfactor needs updating but I think a portable versatile bench meter would be great. I'd particularly like to see some innovation in lead storage. Retractable maybe? eeh, kinda limiting. But something to mean you don't have to unplug the leads and fold/roll them up every day else leave them out taking up inefficient amounts of bench space. We need expandable garden hose multimeter leads
I use a 27 FM for everything almost every day, indestructible. You should send a bunch of us fellow RUclips creators promo versions of your meter so we can help promote it the way to China utilizes influencers as free promoters
I did wonder on a few occasions why you don't run an eev blog meter. Even tho your 27fm is a legend in its own right on your channel. Nice to get them digits working again tho 😁
The only other thing I can think of in the orphan form-factor is the HP 3476A (and B, with batteries!) 1111 counts and a gen-u-ine 3.5mm tall digit bubble LED display. I have one somewhere, I think.
Because it was the first serious MM I ever got to use... at Uni... a Fluke to me is always the gold standard in MM and I won't own anything else. For the same reason I own a Weller... it's years old but does the job well and I likely will never use anything else... I personally don't particularly like this model - but appreciate a Fluke based video nonetheless!
Hi, i hope you can help me! Is there any LCR tester (or Other testing device) that have a “pass/fail with sound or visual confirmation when testing inductance and resistance in transformers ? Like, set the parameters to “234 ~ 274 uH”, if the transformer is within the values, a confirmation sound or light tell me that the transformer is good or bad ? Currently i’m using a “Minipa MX-1050 LCR tester”
The OWON XDM1041 is similar to your idea of a case for the guts of this Fluke meter, have you looked at that model, looks cute but looks can be deceiving?
From Dave Taylor, former Fluke meter designer on the EEVblog forum: "The 37 form factor was requested by corporate buyers because the small handhelds walked out the door too easily. Specifically it was made bigger to prevent theft."
Aneng 8888S is a similar form factor, but instead of the useful compartment, they put in a Bluetooth speaker and alarm clock!
Yep, big disappointment that one!
Just had a look, unbelievable ! fun for all the family.

I was 100% expecting this is a joke.
The Fluke 37 was my very first purchase of quality electronics test kit - back when I was 17yo - and its still being used on my bench today...

Very nice. Ive got an old Fluke 77 from 1987. Full auto ranging and built like a tank. Still works perfectly 36yrs later.

When Dave opens the lid I thought what a great place to put your lunch!
The fact that you haven't been able to buy one of these for decades tells you how popular it was.
Slots in the PCB around the trimming area are for reducing PCB leakage, which can vary wildly depending on cleanliness, flux etc.

I personally don't particularly like this model - but appreciate a Fluke based video nonetheless!
Fluke are interested and work with true RMS oscillator circuit highly accurate !.
What a cool looking meter. I just looked on ebay for one, 2 available, with outragous shipping.
Why don't the video titles numbers have a '#' in front of them since video number 1376?
Hi, i hope you can help me! Is there any LCR tester (or Other testing device) that have a “pass/fail with sound or visual confirmation when testing inductance and resistance in transformers ? Like, set the parameters to “234 ~ 274 uH”, if the transformer is within the values, a confirmation sound or light tell me that the transformer is good or bad ? Currently i’m using a “Minipa MX-1050 LCR tester”
Is the DC Jack not isolated from the inputs? Locks dangerous.
That's why it recessed, just like the input jacks.
That also looks like iron with zinc plating that's kinda common in here for exhaust pipes of gas heaters.
Would you please review the Atten ST-862D hotair rework station? It's apparently slightly better than the Quick 861DW at about $100 less.
Missed opportunity to use the μCurrent to measure the power draw!
You are right, it is a sideways 27
That was a very nice presentation. Thanks.
Dave why not make a bench version of one of your meters? Probably isnt much more work than designing an enclosure?
The OWON XDM1041 is similar to your idea of a case for the guts of this Fluke meter, have you looked at that model, looks cute but looks can be deceiving?
I realized the delay when turning them on is probably a self-calibration/self-test.cycle.
Why you do a video on VTVM. I am pretty sure you must have quite a few. Thanks
you got a cold solder connection under the screw at the fuse!
5:50 battery is vertical should be horizontal to be better secured
Do it up, Davey! Id love to see you make a 3d printed rear case. 😎
