This instruction manual for several Beckman Instruments products was created by the Hanford Site Instrument Department, specifically for use with Beckman instruments used in their facility. Instruments covered in this manual are: the RXG Micro-microammeter, the "Beckman Test Unit," the 800S Controller, the 1709 Automatic Multiple Switch, and the RX pH Meter. It contains instructions, troubleshooting guidelines, charts and diagrams, and corrections and comments handwritten in pencil, presumably by Hanford employees.
The Hanford Site was established in 1943 in Washington (state) as part of the Manhattan Project. One of the reactors at this site was the first full-scale plutonium production reactor in the world. Plutonium from this site was used in the first nuclear bomb, tested at the Trinity site, and in the bomb the United States detonated over Nagasaki, Japan in 1945.
