An excerpt from Cascade Impactor Data Reduction with SR-52 Programmable Calculator, EPA, EPA-600/7-78-226, NOV 1978, 112 pgs.

"                                         ABSTRACT
     This report is intended to provide useful tools for obtaining particle size distributions and graded penetration data from cascade impactor measurements. The programs calculate impactor aerodynamic cut points, total mass collected by the impactor, cumulative mass fraction less than for each stage, log-normal size distribution parameters for the data, and graded penetration. These programs are written specifically for the Texas Instruments SR-52 and TI-59 programmable calculators and the PC-lOOA printer. A general discussion of the program, an example problem, program listing, and user instructions are provided for each program. …

                                         SR-52 PROGRAM SET
GENERAL DISCUSSION
     The SR-52 program set is contained on six magnetic cards that must be executed in the following order: Cards 1, 2, 3, 4, 5 for inlet data; Cards 1, 2, 3, 4, 5 for outlet data; and then Card 6 for combined inlet and outlet data … "
