1. Windows based Download/Graphing program (PDAS3WIN.EXE)
   Requirements: 32 bit Windows operating system
   Installation: Copy program to the desktop or to a folder.
   To run: Start, Run, Browse (to find program where you put it), OK

2. DOS based Download/Graphing program (PDAS3.EXE)
   Requirements: DOS 3.0 or later     
   Installation: Create a directory on your hard disk. (Windows users please
   note: Directory names anywhere in the directory path that exceed 8
   characters will prevent PDAS-3 from finding the sample data files!)
   Copy PDAS-3.EXE to this directory.
   To run: Type PDAS3 and hit the Enter key

3. Windows based file modification utility program (FILECUT.EXE)
   This program will allow you make large ASCII PDAS-3 data files more
   manageable by truncating or removing sections that are not used.
   Requirements: 32 bit Windows operating system
   Installation: Copy program to the desktop or to a folder.
   To run: Start, Run, Browse (to find program where you put it), OK

4. Sample ram-air sport parachute test jump data file in ASCII text format
   (mowdesc.asc) This file includes data from an Industrologic VSI-1000.
   Installation: Copy to the same directory as the PDAS-3 program.
   To use: Select this file from the PDAS-3 program file menu.

5. Sample ringslot cargo parachute test drop data file in ASCII text format
   (ringslot.asc) This file includes data from a 3-axis accelerometer and
   Industrologic VSI-1000.
   Installation: Copy to the same directory as the PDAS-3 program.
   To use: Select this file from the PDAS-3 program file menu.

6. Sample parachute riser load data file in ASCII text format (riser.asc)
   Installation: Copy to the same directory as the PDAS-3 program.
   To use: Select this file from the PDAS-3 program file menu.

   Notes:
   This data was collected by a test jumper using a common sport parachute,
   freefalling to terminal velocity before initiating deployment of the
   parachute.

   This particular parachute was configured for a very soft opening, but
   used with load links amplified for much larger forces, therefore the
   peak loads in this file are small compared to the maximum signal possible.

   In order to provide a smaller sample file, this file has been modified
   from the original file to exclude data at the beginning and end that
   does not include information related to the peak force signals.

   Noise at the beginning of the data is caused by jostling of the load
   links during freefall.

   The Event signal is asserted throughout the data because recording
   was stated in freefall using the Remote Activation Pin switch.

   For the "Plot Parachute Riser Force Data" option, the following entries
   at this screen will permit quick viewing of the riser forces without
   viewing and analyzing the data your self:

                      Set Parachute Riser Force Adjustments

         The following adjustments are entered after viewing raw voltage
             data and noting the no-load and suspended weight values

  Suspended weight of jumper/load . . . . . . . . . . . . . . .  : 250
  Fraction of weight on riser 1 (nominally LEFT FRONT at 0.25)   : .2937198
  Fraction of weight on riser 2 (nominally RIGHT FRONT at 0.25)  : .2937198
  Fraction of weight on riser 3 (nominally LEFT REAR at 0.25)    : .2062801
  Fraction of weight on riser 4 (nominally RIGHT REAR at 0.25)   : .2062801
  Beginning sample number of no-load area of data (e.g. freefall): 100
  Ending sample number of no-load area of data (e.g. freefall)   : 800
  Beginning sample number of straight canopy flight area of data : 10000
  Ending sample number of straight canopy flight area of data    : 11500
  Frequency at which data was sampled (if in data file, enter 1) : 1000
