content: 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.

This model was using a mercury battery model RM.1R, voltage: 1.35v.There are several solutions for the replacement. The easiest one is may be this:http://www.smallbattery.company.org.uk/sbc_mr50_adapter.htmYou could also adapt a 1.5v battery together with such regulator:http://fr.farnell.com/texas-instruments/tps709135dbvt/regul-v-2-7-30v-0-245vdo-1-35v/dp/2314369?Ntt=2314369http://www.farnell.com/datasheets/1882939.pdfHope this helps ...Good luck !

Analog meter is really superior in some works and this meter is one of best.Over all digital scopes and meters I still use analog scope(s) and analog multimeters (In some specific cases relating to maintenance and repair work). Reason is so simple. Money.
