The Close Module consists of data entry similar to the HP41 [R/S].
Data Entry operates from the stack environment that prompts for either the next bearing or distance with line number and last entry for reuse all in the large 7-line display.
Calculate coordinates of traverse at the same time.
Apply datum shifts, linear conversions and angle summations (reverse bearing, add 90 degrees, subtract 90 degrees) during data entry while checking miscloses at any time.
Close Module includes data storage, deletion and editing capabilities from a 2D matrix at any time.
Calculate Unadjusted areas, Bowditched adjusted areas, Angular misclose, 2 missing distances, 2 missing bearings, Missing bearing and distance in different lines, Cut area by two methods (3 unknown distances or one unknown distance and bearing and distance).
You can add calculation solutions to the end of the current matrix.
The current matrix can be bowditched by either a closed traverse or between two fixed coordinated points.
The current matrix can be coordinated and then plotted to the screen.
A print menu is available for headings, current matrix bearings and distances, traverse details and adjusted areas, coordinate listing & plot.
The Coord Module consists of a Tools menu with Job, File and Data storage capabilities.
Calculate bearing and distance between two fixed points.
Calculate a new East and North from a fixed point by bearing and distance.
Calculate East and North by an intersection of two straight lines from four fixed points.
Calculate East and North on a straight line between two fixed points.
Perform Reference Line calculations.
Setout a distance from calculations using Setout Mode.
Convert a coordinate matrix from Close Module for use with Coord Module.
Upload a TXT file from a computer and convert to points.
The Utils Module consists of a Road Secant program with multiple road widths.
Truncate a boundary with any number of chords with Boundary Truncation program.
Enter level book data direct from a level book with Backsights, Intermediate and Foresights.
The program can also allow for un-even change points between forward & reverse runs.
Calculate total of backsights and foresights.
Calculate rises and falls.
Calculate total of rises and falls.
Calculate Unadjusted Reduced Levels.
Calculate Adjusted Reduced Levels by a Double Level Run from 1 Bench Mark.
Calculate Adjusted Reduced Levels by a Single Level Run between 2 Bench Marks.
Calculate Adjusted Reduced Levels by a Double Level Run between 2 Bench Marks.
Toggle Auto Metres or Auto Links.
Set display of misclose, from start to end or reverse.
Change datum correction values.
Choose between the HP82240A or HP82240B infrared printers.
Toggle printer for print output off or on.
Set display FIX for global changes, or applied to bearings, or applied to distances.
Data Storage for all Modules is dependent only
by the available free memory on the calculator
