3.5.1 Starting the Program

Run bqStudio from the desktop. The window consists of a tools panel at the top, and other child windows that can be hidden, docked in various positions or allowed to float as separate windows. When bqStudio first starts up, the main window displays the Gauge Dashboard window, the Registers window, and Data Memory window. Registers, Data Memory, Commands, and other windows can be added to the main window by clicking on the corresponding icon in the tools panel at the top of the main window.

The data appears initially in the Gauge Dashboard, Registers and Data Memory sections. Click the Refresh (single time scan) or the Scan (continuous scan) buttons to update the data in the Registers and Data Memory windows. Continuous scan is enabled when the Scan checkbox is highlighted green and disabled when the Scan checkbox is not highlighted. Set the continuous scanning interval with the stopwatch icon next to the Scan button. When the stopwatch icon is clicked, a drop-down menu appears, and the desired scanning interval can be selected. The scan interval value appears next to the stopwatch icon.

Another way to collect a log file is through the Registers page. To start a log file the "Start Log" button can be pressed, then the desired file name and file location can be chosen. The log file will periodically log everything present in the Registers page.
