This main bus ammeter measured the current from the batteries used in Gemini 3, IV, and VI. Located on the Gemini pilot's panel, the No. 1 scale displayed main batteries 1 and 2 and the No. 2 scale displayed main batteries 3 and 4. Fuel cells replaced batteries on Gemini V and VII through XII. This ammeter did not fly in space. Weston Instruments made the artifact and NASA transferred it to NASM in 1972.
