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.
Have a Look at NEWER VERSIONS ...
