Old Iskra Unimer 2 :) (Metrawatt clone)

(1/3) > >>

Spiro:
Yeap. It is analog instrument with 1-1.5% accuracy. It can measure up to 5000V.
What CAT is that? Lion or tiger ;) Small burden voltage. It is at least 20 years old.

That shows that badge engineering has a long tradition in the multimeter industry. Compare your Unimer 2 to the http://www.radiomuseum.org/r/goerz_unigor_3p3.html Especially have a look at the relays http://www.radiomuseum.org/images/radio/metrawatt_gmbh_vorm/unigor_3p_223315.jpg

I'm not sure it is "badge engineering". If I remember well, Iskra was assembling   those meters under license from Goerz - Metrawatt.
I think they received "kits" of parts (see the Goerz name on the PCB and the German-made relay).

Before Yugoslavia "exploded" Iskra (that means, I believe, Spark) was a really big company that manufactured every kind of electronic and electrical equipment and parts, usually of good to very good quality. They were the only company manufacturing variacs in Europe (or st least the only one to make them available in Italy, in the 70s).

I was more thinking the other way around. Iskra building them, Goerz/Metrawatt (today Gossen) selling them under their name. It was common during those times that Western European companies used companies in Eastern Europe to build and assemble their goods. The WE companies were very careful to disguise the origin of their goods, because sales would go down if it turned out the goods were made by "communists". A little bit like today with stuff manufactured in Asia. So I would not be surprised if Iskra assembled the Unigor 3 or parts of it, too.

I can't believe the circuit board actually says Goerz. Nice to see a backplate that you can actually read in nearly your own language. The Iskra plant was and still is located in the same city I go to school.

Yes Iskra does actually mean spark. A joke regarding the company name is often told. In the sence that their products often release sparks. ;D

Our school has piles of newer Iskra analog multimeters. The quality is not so good (they weren't meant for industrial use) but they all still work.
