I purchased an old itt metric mx 202b multimeter. I've been trying to find a manual and schematic for it. I've found the schematics however all the manuals I can find are in French. As my French is very poor does anyone have one in English. From what I can get the gist of the battery replacement can be an issue and they are circa 1967?. Does anyone know anything about them. It's working and I just liked the look of it and thinking nice to use analogue sometimes. Thanks.
