Desk-top computers equipped with 16K memory and programmed in BASIC can be used to produce calibration calculations for the DuPont ACA II. Entries are made by the operator in accordance with the ...ACA-supplied calibration format and results may be displayed on a video screen and/or programmed for hard copies to be produced by the use of an interfaced line printer. The operator is provided with the option of computing the Y-intercept from a hand-drawn graph, or allowing the computer to calculate it from the slope. The final printout supplies the averages necessary for plotting the calibration curve, slope and intercept of the line, new intercept, new starting point, and new scale factor. The calibration involved on the ACA II is time-consuming and frequently may produce mathematical errors, both of which are eliminated by the use of the described computer program.
