        Do you have a complete schematic diagram of gemini 3 for voltage reference.
        Its seems that 100k is so sensitive full scale and if set in zero the needle of meter is on other side. likewise the battery check is full scale not even can control on preset rheostat inside the pcb.​
        The sensitivity pot has nothing to do with the battery check, something else must be wrong. Here is the power supply:

            Dear Sir,
            Thank you very, very much for sharing this file with me. It was a great kindness, and I truly appreciate your help.

            I am currently looking for the complete circuit schematic of the Gemini-3 device. In the file you shared, I was able to find the internal components and block-level diagrams, but I couldn’t find a full, buildable electronic schematic.

            I would be extremely grateful if you are able to share the complete electronic circuit diagram of the Gemini-3 with me.

            Thank you in advance for your kindness and support.
            Best regards,

            Ali N.


            hi Amigo
            Lithuania is tiny county you can not seek it on the map. even with fat glass. you ask me to give FISHER schematics while i am not in USA,
            not engineer of FISHER lab, not living in USA. i reminder you that you GOT FULLY ARCHIVE FOR FREE, without a payment -!!
            but you ask me to give you my wife, my home, my car be cause you are waiting from me something magic.

            Lithuania is degradant county without electronics. ye, just God gives something for nothing. his name is Allah!​
