Help with very vintage tube capacitor checker

I recently found this old Danish tube equipped capacitor checker (LCR meter):

.

It's a Danameter (type A2) apparently produced in the late 30s.

This picture of the internal is nice:



It suppose to work, but I haven't got a clue how to use it. I've been looking around the web for manual for similar meters but haven't be able to break the code of the apparatus.

The scale of the switch on the left is divided this way:
(from the top, clockwise) ‘bridge’/10 M.F./ 1 M.F./ 100 N.F./ 10 N.F./ 1 N.F./ 100 P.F./ % /1 Ω/10 Ω/100 Ω/1 K Ω/10 K Ω/100 K Ω/1 M Ω/’control’

The pot below on the left ‘open’ and ‘close’ the eye of the tube.

The pot on the top right has two scales:
‘Loss in OHM” – going from 0 to 200
‘tg á - or ‘tg δ’ – (50 per. – 10 .M.F) – going from 0 to 0.8

This nice scale:



has a pot but no hand.

I'm no technician but know that the apparatus should be able to measure resistance in ohm and the value of capacitors; it should be able to measure if capacitors are defect.

Hints - or better - a precise description of the functions of this beautiful piece of vintage tube equipment will be appreciated very much.

COOL!But I don't have a clue how it works but COOL!

Hi Altec,

:tresbon: It is indeed very, very cool, but it would be so much cooler to know how to use it!!!

I wish I had it in my hands, so that I could experiment. Two terminals on the left: C - Capacitors, [R-L] - resistors, inductors

Below is a website with info that might lead to the company that made this unit, or the manuals. Hope this helps.

Let me know what you find out.

Thank you, jetblack for the link.

The Danameter Multiscope is mentioned in the link but only with a reference to an old (Swedish?) technical periodical from the 40s.

The link is a list of "interesting article in Wirselius' old periodicals." The periodicals is to be found iin the library of 'Arboga (a town in Sweden) Electronics History Society" in Sweden. But besides a number (local reference?) the specific periodical is not mentioned.

But I'm still on the case!

And will keep you informed.

Unfortunately the list

Great news!

The link turns out to be an alphabetical list of articles in the Swedish magazine "populär radio" (popular radio). Now I only have to get my hand on the 10 issue of 1946 and go to page 245!

OK I not know how it works but I wonder if it has any historical significance.PBS has a show called history detectives where they research things There is also the Smithsonian Institute might be able to help.I think its worth more in terms of historical than practical use.IT looks very rare and could be very valuable.:yes: By the way,How did you get it?!

Thx Altec,

I'm not sure it is that rare here in Denmark (or Scandinavia). And I wonder if it is valuable. By the historical value is there!

And a capacitor is a capacitor (is a capacitor to misquote Gertrude Stein) so if it is working it might be as good to test a old capacitor, as it were in the 30s and 40s. We'll see!

Good morning from Denmark on a sunny day
