CCCP era Standard -- R4833 -- Need docs
« on: June 24, 2023, 02:47:57 pm »
Hello Everyone,

I formely bought the item on Ebay. A big box with big rottary buttons. At the beginning I tought this was a resistor standard but there are many other modes.

With many tries, I found the resistor standard part posts and manage to make that work. The thing is very precise but the tenth of thousands is off quite a bit.

I found nothing on it. Does anyone have any information about this box, diagrams maybe...???

Thank you A LOT!
I'll go practice my russian!

Here are some pictures of the insides for the enthousiats!

convert any pics (like this pdf file) on OCR program (ABBYY finereader) to text
and translate this on google (or yandex) translator to any language

 ;D
it`s a simple (but work is hard)

The passport is from April 2014 - that is interesting.. Still in the production 23 years after the dissolution of CCCP.
Readers discretion is advised..

Why? Just because the USSR got dissolved does not mean all the factories inside the USSR got dissolved. It wouldn't surprise me if some of these factories were still producing.

Perhaps the reason the tenths of thousands is "off" a bit is because of the connections. Banana jacks can be problematic and there may be voltages induced with different metal to metal connections. Perhaps try clean good solid copper wire for these measurements with direct connections. Not even solder. Do you have any old coax? If you have junk coax with solid copper center that should do nicely.
Those wire wound resistors are quite stable and will give you good hobby grade standards for a very long time.Nice condition too.
It looks like a resistance bridge and you may be able to figure out the different modes by perhaps looking at something like a General Radio or Biddle Wheatstone bridge and see if you can compare the switches and connectors.
Besides being a resistance box and a bridge for measuring an unknown, these thing have other interesting modes, most of which I am not experienced enough to intelligently comment on. These modes can find a distance to fault, for example, I think they are called MUR Functions?

Not in production anymore. Lets called it post-CCCP era in Ukraine, when Yanukovych was president.

There is literally a CCCP logo on it...

Another link to manual:

No way to find it in English, only in Russian.

So, in what parts of the instruction you most interested in? "How to use"? )

I would not touch it without radioactivity check, even if not radioactive it still may be very toxic.

This device has 3 main functions:
1. DC bridge for resistance comparison
2. Decade resistor box
3. Voltage divider

CCCP devices had always many hidden fetures, like famous in Polnad russian TV called Rubin.
The only safe way to watch this TV was wear helmet and goggles,  with fire extinguisher nearby.
They tend to use toxic components in everything, not only in spy devices.

...

p.s
above is not a joke, but this below is:

'polish communist leader asked Mao one day visiting China -  How many people in China are against communism/red army - Mao said ' 40 milions', polish red leader answered - 'ooo, what a similarity! we have 40 millions as well'
