R E M A R K S T O R E S T O R A T I O N : ---------------------------------------------------------------------------- This Multimeter came in bad shape: Dirty, glass loose, case-edges broken and not woking. After soldering disconnected wires, there was a surprise: The Volt- & Amp- Ranges are extreme precise! But the Ohm-Ranges were off. There was a broken resistor and a bad one. Both replaced (by trial-&-error) until good results were accomplished. To repair the broken case, inner forms were made of aluminum strips, hold in place by chewing gum. Tapes made the outer forms. Than 2-Component-Glue was filled in between ... After hardening, the final form was filed out ... ... and finally painted with black marker. The glass was fixed & sealed with a frame of cardboard. The damaged plugs were replaced by RED & BLUE ones.
