>>3176868>Kodalux L selenium light meterDont know about that particular one. I have a "Made in Japan" meter, the selenium element is connected to meter needle and nothing else.
1: Set (A) ASA/DIN (ISO) to whatever you use
2: Point to whatever and read (B) needle (its more visible than in my shameful snap)
3: Turn dial so it matches the reading.
4: Profit.
This one is pretty useless in dim light. But when it works it works ok.
