I recently acquired a Zeiss Icon Contessa in Ex condition but with a very dead light meter. After an autopsy determined the metering mechanism was okay, I removed the selenium wafer behind the `window’ and found it had zero voltage under light. With nothing to lose, I took a much larger wafer from a working but scruffy $3 junk store meter and cut it to size (along 2 edges - verry gently to avoid cracking the coating) with a pair of aircraft shears. Then, as I didn’t have lacquer handy I ran crazy glue around the naked edges just to re-seal them.
Once in place, the tricky part was ensuring an electrical connection with the front of the selenium wafer, but a little creative scraping & fiddling ensured a good contact.
Believe it or not, it now meters accurately. I was advised this approach wouldn’t work, but so far at least, it’s done the job. Naturally, I would think this `low-risk fix’ might apply to many other similarly metered units as well.
