This meter is really cool:



Can anyone figure out the labelling? It says "MULITMETER UNIVERSAL <something> V7-16" at the top but the rest has me stumped. In one picture the prefix tube shows a capital letter pi (∏) instead of the usual plus and minus. I have no clue what that means.

cool, but pricey

I think it says "Вольтметр универсальный В7-16" at the top. If you google that, you can find some webpages with more info.

I do like the look of these multimeters, but the biggest challenge for using them for me would be the 220V input

It has a 110V/220V switch at the back. Jens

there are cyrillic keyboards online, you can use to type the text, then use a translator to translate to the nearest English equivalent.

is what it says at the top, sort of

I picked up a 120 to 240V step-up transformer at Radio Shack years ago and use it for many such things.  I grabbed a second one on the cheap when they were going out of business.  They're handy.

Guys, there is a switch in the back!

Hi

It says  Вольтметр универсальный,  which was simply translated,  as  voltmeter universal. it could measure wide  range of voltage  from 1v to 1000v   with switch choice  of high or low frequency signal. I think it could work with AC and DC input

I would not say it's multimeter, as I can see,  it cannot measure amps, ohms and so on...

Sign "П" meas "Перегрузка"  when input signal is out of range... 

I still use V7-27, which is good one and it is multimeter...



All the best, Konstantin

That's a fine site you keep!

Oops. I read it that way but mis-remembered it when I typed the post. I guess my Russian isn't half bad but my short term memory stinks. 8D

Ah, the resistances must be input impedances.

Thank you for that! Could you translate some of the other markings for us?


BTW, I used to work for what is now known as The Rosetta Stone® during their formative years. I was the jack of all trades there and amongst  many other things handled the documentation for all the languages with non-Roman scripts. I have lots of experience with text I can't actually read. Sort of like the monks in the Middle Ages who copied Bibles and other books without reading or writing Latin or Greek.

The switch next to voltage is 50 or 400 Hz.  Not really compatible with North American 60 Hz.   Only place I see 400 Hz is in aircraft systems, not common usage.   Does it use the input frequency for a time base ?

The switch next to it selects between 115V/230V. Why wouldn't it work with 60Hz? Probably fine. Jens

there is a lot less iron needed in a transformer for 400Hz. so probably
the 400hz side cuts out part of the winding of the transformer to
compensate. a 50Hz transformer should be close on 60Hz. I have an
ancient TV set that I used for about a year when I was a kid before I
noticed it was a 25Hz set. In that case, again the transformer was
massive and so the internal voltages were so high that the Picture tube
was very worn.

Yes, Resistances shown on the front panel are input impedances.

Here are a few other translations:

ПРЕДЕЛ ИЗМЕРЕНИЯ = RANGE

СЕТЬ = MAINS

РОД РАБОТЫ = MODE

КОНТР. =  КОНТРОЛЬ =  CHECK POINTS

ВР. ИНД. = ВРЕМЯ ИНДИКАЦИИ =  INDICATION TIME

ВЧ = ВЫСОКАЯ ЧАСТОТА = HIGH FREQUENCY

НЧ = НИЗКАЯ ЧАСТОТА = LOW FREQUENCY

СДЕЛАНО В СССР = MADE IN USSR  ;-)

 

The rest sings are quite international or not clear ;-)) and  requires  to read Manual ...

Phil is right.

This true about 400 Hz... you know the reason that frequency is used in aircraft?  For those that don't know... it doesn't require transformers or motors that are as large for higher frequency so thus it weighs less.

Thank you very much for that. One other question: in the first picture the display reads "П53.20kΩ". The switch is set to "100kΩ - 100V". What does this mean exactly? I can't figure out what this thing is measuring. What was it used for?

If it were about $150 with shipping...

I don't know about frequency or if it was even AC but trains used a lower voltage, something like 60V. I have a passenger car light bulb that I can't get to it right now to check. The bulb is screwed into a socket with a large spring between it and a male Edison screw at the end. I guess it absorbed vibrations and kept the filaments from breaking more often.

Cable TV line amplifiers used 30V or 60V, 60Hz square wave AC back in the '80s when I worked at ComSonics. I don't know if that's changed since then or not but the power supplies had special transformers designed to handle square wave AC. The reason they didn't use sine wave was because the battery backup power supplies could only produce square.

There was one line extender made by a well-known company that had an alarming tendency to fry its (expensive) transformer. The cause was simple. Some genius put the fuse between the bridge rectifier and the filter caps, not between the transformer and the diodes. A few surges and zap, a diode shorted out and overheated the transformer until a winding melted open. If the customer paid extra for a one or two year warranty we put surge protectors on them and that solved the problem. We hardly ever had to repair an amp after we put one in it. After a few months an engineer from the well-konwn company called us to ask what the hell we were doing to their product to keep it from burning up.

True story, can't make stuff like this up. In 1983 the need for surge protection was not well understood even with commercial electronics. Lightening arrestors, yes (we replaced a lot of them). In fact, the surge protectors we used were designed by the owner of the company and custom manufactured in-house.

There was one ancient power supply (no PC board, just point-to-point wiring) that had a failure mode where it kicked back a voltage so high the arrestor on the input would ionize and light up.

I have to find User manual and read why it displays resistance. It can measure  active resistance of circuit impedance. 
So "П" in  "П53.20kΩ" means that active resistance on measured circuit is more than 100k.
 Why it shows  53.20kOhm which is within 100k range and "П" I have no idea...;-(
