The LSS Miracle Software for the HP 35s Calculator : 

The LSS Miracle Software for the HP 35s Calculator TAPE ADJUSTMENTS Program (M) ___________________________________________________ Overview and explanation This program computes tape correction values from inputs for tape temperature, sag, pull, tape cross-section, and weight. ___________________________________________________ WARNING: Do not remove the batteries for more than two minutes or use the “CLEAR” “ALL” function or the programs in the calculator will be destroyed. Please read the first two pages of the manual that comes with the pre-programmed calculator before attempting to operate it.

The LSS Miracle Software for the HP 35s Calculator : 

The LSS Miracle Software for the HP 35s Calculator This program allows the User to compute tape corrections by inputting the following information following the appropriate prompts: Standard Temperature Variable in Fahrenheit or Centigrade Degrees Standard Length Variable in Feet or Meters Standard Pull Variable in Pounds or Kilograms Static Cross-Section Variable in Square Inches or Square Centimeters

The LSS Miracle Software for the HP 35s Calculator : 

The LSS Miracle Software for the HP 35s Calculator This program also allows the User to compute tape corrections by inputting the following information following the appropriate prompts: Standard Weight Variable in Pounds/Foot or Kilograms/Meter .Current Length Variable in Feet or Meters .Current Temperature Variable in Fahrenheit or Centigrade Degrees .Current Pull Variable in Pounds or Kilograms

The LSS Miracle Software for the HP 35s Calculator : 

The LSS Miracle Software for the HP 35s Calculator From this input information, the program solves for the following information and displays the results in both Feet and Meters for both Supported and Unsupported cases: Length of the Tape Being Used Tape Length Correction Temperature Correction Pull Correction Sag Correction Grade Correction Adjusted Current Layout Distance Adjusted Current Measured Distance

The LSS Miracle Software for the HP 35s Calculator : 

The LSS Miracle Software for the HP 35s Calculator Since the HP 35s calculator does not allow programs to prompt for user entry the protocol used is to describe to the user the variable to be entered or displayed and then display or request that variable after the user enters a “R/S”. Variable queries are shown with a variable character name (A through Z) followed by a question mark (?). Responses to queries with a value of zero “0" cause the program to ignore that parameter.

The LSS Miracle Software for the HP 35s Calculator The following two problems are taken from Elementary Surveying, by Paul R. Wolf and Russell C. Brinker. PARTIAL PROBLEM #1 (Example 6.1, page 143): A 30 meter (“m”) steel tape standardized at 20° Centigrade (“C”) and supported throughout under a tension of 5.45 kilograms (“kg”) was found to be 30.012 meters (“m”) long. The tape had a cross-sectional area of 0.050 square centimeters (“cm2") and a weight of 0.03967 kilograms per meter (“kg/m”). This tape was held horizontal, supported at the ends only, with a constant tension of 9.09 kilograms (“kg”) to measure a line with a length of 21.151 meters at a temperature of 16° centigrade. Solution: Length Correction: +0.0278 ft or +0.0085 m. Temperature Correction: -0.0032 ft or -0.0010 m. Pull Correction: +0.0025 ft or +0.0008 m. Sag Correction: -0.0246 ft or -0.0075 m. Grade Correction: 0.0000 ft or 0.0000 m. Unsupported Layout Len: 69.3954 ft /21.1517 m. Unsupported Measured Len: 69.3907 ft /21.1503 m. Supported Layout Len: 69.4201 ft /21.1592 m. Supported Measured Len: 69.3660 ft /21.1428 m.

The LSS Miracle Software for the HP 35s Calculator The following two problems are taken from Elementary Surveying, by Paul R. Wolf and Russell C. Brinker. PROBLEM #2 (Example 6.2, page 144): A 100 foot steel tape standardized at 68° Fahrenheit (“F”) and supported throughout under a tension of 20 pounds (“lbs”) was found to be 100.012 feet (“ft”) long. The tape had a cross-sectional area of 0.0078 square inches (“in2") and a weight of 0.0266 pounds per foot (“lbs/ft). This tape is to be used to lay out a horizontal distance of exactly 175.00 feet (“ft”). The ground is on a smooth 3 percent (3%) grade, thus the tape will be fully supported. Determine the correct slope distance to lay out if a pull of 15 pounds (“lbs”) is used and the temperature is 87° Fahrenheit (“F”). Solution: Length Correction: +0.021 ft or +0.0064 m. Temperature Correction: +0.0214 ft or +0.0065 m. Pull Correction: -0.0039 ft or -0.0012 m. Sag Correction: -0.7022 ft or -0.2140 m. Grade Correction: -0.0787 ft or -0.0240 m. Unsupported Layout Len: 174.3363 ft /53.1377 m. Unsupported Measured Len: 175.6637 ft /53.5423 m. Supported Layout Len: 175.0386 ft /53.3518 m. Supported Measured Len: 174.9614 ft /53.3282 m.
