4.7.4 Project menu Figure 4-19 The Object Properties - General dialog Figure 4-20 The Project menu Run runs data acquisition or import of data. It also allows the user to recalculate the objects in the project. Repetitive runs all objects repetitively for the current position, without storing data to disk. Useful when setting the system up. You can change the settings of the processor while Repetitive is running, and see the result of the change immediately, both in graph and list windows and in the system monitor. Recalculate Re-runs calculation objects (e.g. Moments, Transform, Spectrum, Cyclic Phenomena) Stop Stops data acquisition 4.7.5 Tools menu Figure 4-21 The Tools menu Note It is recommended that all the general options are enabled. 4-20 BSA Flow Software: The user interface
Options With the Options you get a dialog with five tabs, the first of which is General: The General tab shows general properties and user information. Figure 4-22 The Tools - Options - General dialog If Provide feedback with sound is checked, the PC will beep e.g. when data collection is started and completed. With Show start-up dialog checked, the start page is shown when you start the software – see section 4-4. If Show warning prompt when overwriting data is checked, the Data Overwrite Warning dialog is displayed every time an experiment is about to overwrite original data. In the Data Overwrite Warning dialog you can choose to skip this dialog the next time by unchecking Show this at next run; this is however not recommended. BSA Flow Software: The user interface 4-21
