Scope and content
A technician's hands are pictured carefully turning knobs on February 28, 1957, as he is apparently running quality control tests. Several small post-it notes with negative numbers and letters are located nearby. Voltage can be measured from 0 to 135 volts on this machine. The compensator and reflection scale can apparently be adjusted. It is possible that these quality control tests would measure the whiteness of paper.
