Presenting the BBB, the Beast, the Beauty and the Brick ? 

I like it. 

[Helix70]

The 87 is the beast or the beauty?

[BravoV]

The 87 is the beast or the beauty?

The honor to decide which is which, is yours.   

[Helix70]

Ok, Beauty, Beast, Brick in that order

Also, I have a very specific problem with a T&M instrument from Italy: I own a 'fast transient monitor' from the deceased company 'Ingeneria Guido Gay', the FTM30.
If it is of comparable quality like his memory voltmeters (which I use), it should be good. That feller was a analogue wizard and designer of nice instruments! But I have been unable to find ANY information about it! Even to check it out, would need some manual. Any idea? I would be sincerely delighted!

I never heard about "Ingegneria Guido Gay". I did a quick search and found this page  http://www.underwateracademy.org/it/press-area/archivio-news/16-biografie-tridenti/1980-1989/140-1985-guido-gay.html where is reparted about a submarine robot and the discovery if a WW2 wrech, but I don't know if he is the same Guido Gay.
Best regards

It is the right guy that you've found. Also 'Gay Misuratori Elettronici' is the correct company name.
That he was active in underwater robotics was not known to me before.
Here are my two MTA memory voltmeters (peak voltmeters) from his company:
But for those I have documentation. The other two pictures show the FTM, whose case remains, unfortunately, unsolved.

You've just reminded me that I have one of those MTA memory voltmeters stashed at the back of the cupboard. The battery is obviously shot (again - I replaced it when I got it, about 25 years ago but it hasn't been charged since ). The only documentation I have on it so far is the spec... http://helmut-singer.de/pdf/gaymta.pdf.

Regarding your FTM, they appear to have made (at least) two mains voltage monitors, the LVA and an 'unknown' model - that's from the Telford Electronics manuals list... http://www.telford-electronics.co.uk/manual.php?alpha=g. They might possibly be able to help you.


EDIT: I've spotted a listing for an FTA (Fast Transient Monitor) on ebay, maybe the seller has some information? https://www.ebay.co.uk/itm/Fast-Transient-Monitor-FTM/222411921416?hash=item33c8c89808:g:L1cAAOSwWxNYpdVj. A nice looking piece of equipment, sounds ex-MOD.

EDIT: Well the MTA still works and reads fine after all these years. The battery is well gone (longer than I thought since I changed it, datecode 1989!). Very few electrolytics in there, but the Orange one looks pretty sad. While I had it apart, it seemed worth taking a couple of snaps (outer metal shell removed + inner isolated case lids)...

Yup, it's a really nice instrument.
Should you need the manual (with diagram) of the MTA, that could be arranged. But only if not too pressing, as I'm quite swamped with things to do.

As for the FTM, the offered one has pics showing the special (reverse Lemo?) input connectors. When I saw them first, I thought about replacing them, but their inner side is under a massive soldered copper sheet cover which clearly says 'magic - keep out or be damned'.

That's very kind of you, thanks! No, it's absolutely not pressing (it still works) but it would be nice to match it up with a scan of the manual.  I could upload it to KO4BB too, if you have no objection.

I hope you have some luck with the FTM. Those look like the same connectors as the MTA (luckily mine came with a lead). Yes I suspect that they are Lemo triax but I haven't managed to identify which one. Now all I need to do is find the MTA mains lead, I tested it earlier by jumpering the battery. It's a non-standard mains connector - I just hope I haven't forgotten what it was for in past years and 'salvaged' the cable. 

Thanks again,

Chris

Edit: Aha, looking on ebay, there seem to be a lot of Lemo triax connectors - and strangely, they're all in Germany!  There appear to be sizes 0s, 1s, and 2s though, so a little bit of research needed. Not ridiculously expensive though. https://www.ebay.co.uk/sch/i.html?_from=R40&_sacat=0&_nkw=lemo+triax&LH_PrefLoc=2&_sop=15 There are some copies from China too.


LATER EDIT: I have uploaded the GAY MTA manuals to KO4BB. Thanks again to Neomys Sapiens for scanning them!    http://www.ko4bb.com/getsimple/index.php?id=manuals&dir=06_Misc_Test_Equipment/GAY

My old, kind friend. How many times he helped me in different situations.

Seriously, I have two Fluke 77's that are probably 20 years old, work great, are still in cal, and I see no need to replace them.
(and yes, that's really one of my meters in the photo)

Now that is a vintage DVM!

The 3440a is cool, but its grandfather is even cooler

And it autoranges, too!

Never seen one before...cool

Here's my Hyelec/Peakmeter PM8236 and PM2028B.

By the way, is it safe to replace the 250V/600mA and 250V/10A fuses in the PM8236 with 1000V fuses of the same current rating?

I've asked the manufacturer and the answer was "yes", but I'd like to seek reassurances from everyone... thank you!

My analog multimeter has a beeper. Very useful function.

Oh. 

Are those 1999 or 9999 digit units?

You mean counts, not digits. Digits means the number of places, e.g. 9999 counts is 4 digits, and 1999 counts is 3.5 digits.

[willb]

Picked up 2 more AVO meters, with their cases! One is a military version (with the NATO stock number). My collection is growing.

[Martin.M]

that Philips PM2421 are 1999 counts.
amazing is they can test also  nA and R up to 2G

Philips Icoma,  Low-Ohm-Meter, 4 wires, warm 
1-3-10-30-100-300 Ohm full scale, test frequency = 10kHz
it works like a combination of a low ohm sine wave osc. with a frequency selektive mV Meter, well calibrated to test the R with the 10kHz
this instrument may be the grandpa of ESR testers, it was at home in the Valvo Manufacturing for capacitors.

Yes. Cunts  Actually 9999 would be something like 3.98 digits, sales officer would call it 6 digits, since there is sign and radix.

I got a new meter and I mean NEW. Heck I have not bought a new meter I think in past 15 years.

This little and cute meter is second best in the market (in its class), what I did found. The mechanical design is really satisfying and so nice compared to all the rubber bricks mainly floating in the market today. This one is "Made in Japan" unit and not the "$anMa made in hing kung".

Sanwa EM7000 a "modern" FET VOM, how I could resist and I didn't.
