The typical screen shown above is for a Velocity vs Time graph with only the positive y axis displayed The measurement parameter VEL is shown to the left of the y axis and there is a message line below the graph that initially indicates the starting date and time of the graphed data Notice that most of the locator bar has been replaced by a status line in standard video that shows the value units and time of the measurement at the current cursor location However there is still an inverse video pointer at the far right of this line to indicate that additional option bar choices are available Note The date in the message line includes only the day and the month not the year and the times in the status line and the message line include only the hours and minutes not the seconds Because the times displayed in the GRAPH format are in whole minutes only movement of the cursor may not result in a visible change in the posted times For example if a TIME INCREMENT of 30 seconds has been programmed two presses of either cursor movement key will be required to change the displayed time by one minute Table 6 Graph Display Options Option Bar Choice Description F1 2 CURS Moves the cursor to the left and displays the corresponding measurement value and time in the status line i e 6 85 Ft s 10 38 F2 CURS gt Moves the cursor to the right and displays the corresponding measurement value and time in the status line i e 5 31
