Chapter 3 includes descriptions of the following: • installation of the software and hardware • cable connections 2.3.3 Reference information Chapter 4 gives a detailed overview of the user interface and gives an overview of the windows and menus. It further includes procedures for • acquiring data step by step • re-acquisition of data • re-analysing existing data Chapter 5 describes the property editor. Chapter 6 describes the use of options and add-ons. Your system may include some or all of these. Chapter 7 includes general LDA and PDA theory and descriptions of the data analysis algorithms used in the software. 2-4 BSA Flow Software: Introduction
2.3.4 Trouble shooting 2.3.5 On-line help 2.4 General nomenclature 2.5 Conventions Chapter 8 provides instructions on how to check connections from hardware to software. The software is prepared for addition of on-line help, but this is not implemented at present. The following nomenclature is used throughout this manual and the User’s Guide: processor BSA processor software the BSA Flow Software 2.6 File naming conventions 2.6.1 Project and sample files 2.6.2 Templates PC the PC connected to the LDA/PDA system, on which the BSA Flow software is installed • Warning, Caution and Note are three different ways of highlighting important matters: • Warnings are used when improper operation may result in risks for you or other people in the room. • Cautions are used when improper operation may result in risks for the apparatus. • Notes are used when improper operation may result in an unreliable function of the apparatus. The entire system configuration including acquired data for each experiment is stored in a so-called Project file. Project files have the filename extension LDA. The sample files or sample projects are identical to project files and therefore also have the filename extension LDA. Complete experiment setups or parts of it (branches) can be stored as templates to facilitate re-use in new projects. Two template types are available: Project Templates and Templates. Project templates include the total experimental setup. Project templates have the filename extension LDP. Templates include parts of an experimental setup. Template files have the filename extension LDT. BSA Flow Software: Introduction 2-5
