Dzien Dobry! I bought this selective level meter (miernik poziomu) from a guy when I was in Warsaw back in 2021. I tried my best to use google to find any information on this device (user manual, service manual, product broachure, information sheet) but all I get to see is an advertisement in Allegro. So I am requsting you guys, if you could find any info on this. You may try asking someone who worked in old landline phone companies, because this device used in the telefon lines in 70s/80s. The functionalities of the most knobs is already known to me (with help from local and online helpers) but one thing none can surely say is what MS and MZ means in the most left selector switch (the one with red triangles). Is there some polish words with initials MS and MZ which relates to bandwith of radio signal or bandwith of a filter? It should be something related, e.g. narrow band, broad band, wide band (I am just guessing). If you could help me understand those two letter word, or with any information about the device (manual, datasheet) that will be very useful. Thanks a lot in advance.
