Usage conditions apply
This computing device measures the length of lines, both straight and curved, as well as the area enclosed by curves. It shows the results on a digital readout to a scale set by the user. It also computes the sum of both lengths and areas, and the difference between a larger area or length and a smaller one, again showing a digital result.
The metal base rolls on two metal wheels and connects to a metal arm with cursor and handle. A cable that extends from the back of the base connects to a display panel, a keypad, and a power adapter. A short black arm stored at the front of the case connects to the back of the base and serves as a guide for the cable.
Three sets of sheets were received with the object. One is entitled: BRIEF INSTRUCTIONS. The second is entitled: INSTRUCTION SUPPLEMENT FOR LASICO MODEL 1282C. The third is entitled: SERIES 1282 PLANIMETER / DIGITIZER.
The donor, Maximilian Berktold (b. 1929), immigrated from Kempten-Allgäu, West Germany, in 1950 and almost immediately began working for the Los Angeles Scientific Instrument Company. He oversaw design and production of the firm's planimeters, integrators, pantographs, and various optical instruments until Lasico closed in 2008. According to the Berktold, he built the planimeter/digitizer in 1996. It sold for a list price of $1425.00, with additional shipping costs of $47.10. The donation was made in 2016.
