Alan Zero Corrections – changes in baseline if I recall correctly (think sliding scale). it’s been a few centuries since I played with such things…8*)

BTW, pardon the double post up top – thought I pressed the wrong button and rewrote it again.

Does that refer to a mean or to zero errors? Thanks, Mr C-

The data was generated manually (for example, an engineer might measure the frequency response of a circuit or a chemist the concentrations of a chemical in solution), enter the data in his ever-handy notebook, then some galley slave of an assistant would punch it into this beast. After that, the machine would regurgitate the data, neatly plotted on a chart, arranged as a table (sort routine) or punched onto cards for further manipulation on a "computer".

What this monster is designed to do is to date data gathered manually (changes in the concentration of a solution as temperature changes, or changes in the response of a tuned circuit under frequency changes, for examples) and do the math (mechanically) and plot the resulting data on a nice chart. I can do the same on my HP calculator...and it doesn't weigh 1500 pounds. This is a prehistoric printer/plotter.
