Show your Multimeter!

[soldar]

ASMOF, I've got a couple of even older METRIX model 460:

... and even a much older Neuberger Voltmeter from the '30s or early '40s. A true relic!

Those belong in a museum!

....only out of my cold dead hands.  ;-))
Since these are "Dreheiseninstrumente" moving magnet- (??) instruments one can
use them for AC and DC hence the "stretched" scale.
Also have 8 Multimeters at one GPIB-address (plus DAC and PSU).

Supreme Model 222!

I want one. I WANT ONE! I WANT ONE!!!

And I promise not to let any of my drool drip on it.

I have the typical 8000 series bench Flukes and a trusty old 77 which I use but I'll bore you with a few unique early meters in my test equipment collection.

Supreme Instruments 1934  model 222 "Multometer".  Back then test equipment was functional art.


This one is just a Continuity Tester but interesting just the same.  It's from the late 1920s.
When a short is detected across the two chrome bars the red dot on the needle moves out of the window on the meter. If the dot does not move the item under test is open.


The Manhattan DC Polarity-Indicator was patented in 1905 and shows polarity in a DC circuit using a liquid in a glass tube that when current is passed through it, the liquid in the negative end turns red. They used a liquid filled glass tube that is in a hard rubber type case with a connector on each end. Electrodes inside the glass tube attach to the connectors. The metal sleeve can be rotated to cover the glass windows when carried in your pocket.

FYI:  They still work!

The Simpson 221 (around 1951) - Interesting as the meter scale mechanically rotates with the range selection knob so you don't read the wrong scale.

I found these two old instruments, just the galvanometers which must have belonged in some multimeters.  I am in a bit of a hurry now so I will just post the pictures and comment later. In the meanwhile, any ideas where they might have come from or what each scale measures?

The last to join my hoard was a Tektronix DMM 914 but I'm not showing it, nothing too exotic about it.

Instead a photo of one I don't own that tempts me (just for the aesthetics) every time I see one for sale.

Beautiful!

So I'll throw in something too, although it's my own production, but very useful for my needs. Quadruple independent voltmeter +/- 200V with an accuracy of 0.1% and that is absolutely enough for orientation measurements, the idea of its production was born during the repair of a motor card from an industrial CNC and I needed to simultaneously monitor 60 ; 24; +/- 15 and 5V. He also got a job repairing audio equipment, measuring devices, etc.

The protective film has not yet been removed during the tests.

Well, not really. I used to use it when aligning the IF in radios. DMMs are not up to the task. Now I've got a VTVM and the ICE 680-R is almost never seeing the light out of its drawer but there are things for which a good analog multimeter is still essential. The subtle movements of an analog needle are not easily obtainable with a DMM.

Of course my ICE 680-R rests in its drawer without a battery inside. No need either for its completely outdated ohm metering capabilities nor for a hideous battery, waiting there to leak and destroy the whole instrument... and I also have two or three of those 2R10 batteries in their original blisters from the heyday:

I agree that sometimes a mechanical needle provides a smoothing / dampening which can be useful with unstable signals when the digits of a digital display would just be jumping around and provide no useful info.

By the way, for you or anyone else who might be interested, I have the manual in Spanish. It is like 78 pages so would be 39 scans. Not that I am keen on doing it but if anyone really wants it maybe I could get myself to do it.

Here are a couple of pages.

wah  some rarities here,  yes  some needs to be put in a museum

There's no need for that, Soldar. The spanish manual is easily obtainable from the web. I've got the complete scans (pdf) for the version 4 of the spanish version. If you (or anyone) want it just drop me a note...

I also have the original printed manual

This utterly unremarkable DMM was purchased mail order for about $50 in 1991 as part of a group buy by me and my fellow first year EE students.

It has worked perfectly for 33 years and I still often reach for it despite having a bunch of better, more accurate, and modem meters.

You don't forget you first, I guess.

Thanks for asking about my multimeter. It's been a real lifesaver for all my DIY projects around the house. Recently, though, I've been thinking about upgrading to a newer model for some added features and accuracy.
I came across this catalogue with a wide range of multimeters, and now I'm in a bit of a dilemma trying to decide which one to go for. There are so many options to choose from, each with its own set of specifications and benefits. It's definitely a tough decision to make, but I'm excited to find the perfect upgrade for my toolkit.

Is that so?

[opabob]

On the bench I have a 34401.  Everything else I have an old Fluke 77.  Not a III or a IV, just a straight 77.

The Norma "Normameter 910"

An odd meter with an odd layout, 4.5 digits of unusual niceness. Also of note is the Ever Ready PP3 in the battery compartment dated 9812, and still measuring 9.3V!


EDIT: idk why the pic is rotated; it's something the forum did

[armandine2]

just to test that
