5. Preset Programs
Your calculator includes preset programs for performing civil engineering and surveying
calculations. These preset programs can be run, edited, and deleted, the same way as
programs created by you.
Note
• For information about the procedures required to run, edit, and delete programs, refer to
Chapter 6 of this manual.
• Each program uses variables (A through Z) when running. Note that running a program may
replace the value currently assigned to a variable with a different one.
• When running a program, refer to the figures and formulas in the following section (Preset
Program List), and enter the required values for calculation. Note that you will not be able to
obtain correct results if you enter a value that is not consistent with the illustration shown for
the applicable program.
