This markis not used by the instrument, but is available for the user andmay indicate a significant event, such as the addition of asample or other reagent. The mark is also shown in the table.• Select Stop to stop taking sample readings.6.7.3 Analysis of time course dataAfter the Time Course data has been collected, the followingmanipulations can be done on the graphic data:The Time Course Program is complete, if• the instruments beeps after completion of the overall time• the graph is shown full-size,• the scaling of the x-axis occurs automatically,• the Cursor functions in the vertical navigation bar arehighlighted.6.7.3.1 Navigation of a time scan or a time scan analysisAfter a time scan has been completed, the time and theabsorbance/transmittance data is displayed as a curve.Where the cursor is positioned on the curve, the elapsed time upto this point and the corresponding absorbance are highlighted.Table 17 Navigating the time scanCursor function/Zoom function DescriptionCurve Icon(Choice of Cursor Mode)Delta mode: A second cursor is highlighted. The position of the fixed cursor was previouslydefined in Cursor mode Single. Use the active cursor to select any point on the reading curve.The difference to the fixed cursor is shown on the curve. The delta values are correspondinglyhighlighted and displayed on the x and y axes.The gradient of the curve and the correlation coefficient (r 2 ) between the cursor points in theDelta mode are shown under the curve.Cursor mode, single: The cursor moves to each selected measuring point of the scan.Arrow keysThe arrow keys (right/left) are used to move the cursor (depending on the selected mode) to thenext data point. The data of the data point (wavelength, absorbance or transmittance value) arehighlighted on the x and y axes.Note: Press any point on the curve to display the associated data.Zoom Icon This function is used to magnify the section of the curve in the vicinity of the cursor. The originalcurve size can be restored by pressing the zoom icon again.
