label: Description
content: It then describes typical problems that could be solved with the instrument: plotting a family of curves; reading printed graphs without having to replot them; reproducing drawings at unusual scales; normalizing curves; interpolating points; counting frequency cycles; enlarging or reducing diagrams; determining pressure ratios; solving navigation and center of gravity problems; reading oscillograms and aerial photographs; spacing rivets; setting up engineering scales; determining a rate of elevation; estimating functions; and multiplying and dividing. The company sold specially-sized graph paper that could be laid on the base in order to plot curves.
