Program Flow Chart
In this section the Program Flow Chart is broken down into four sections: Power ON, Performing
a Test, Viewing Test Details, and Viewing Previously Collected Data.
In the flow charts, the boxes represent the display messages seen on the LCD of the screener.
The lines in between boxes show the software flow direction as indicated by the arrow. The text
beside the flow arrows indicates how the step is initiated. For example, the text may describe a
button press or a condition that initiates an automatic progression to the next step.
The paragraphs below the flow chart provide information that is not covered in the flow chart
format.
