available. Use this screen to enter the date and time to display the desired data. Click OK to set
the start and end times, or click Cancel to delete any changes.
• Start Updating: Click this button, and the system regularly checks the database for new data. If
new data is found, the newest data point is added to the right s ide of the graph. All other data
points are shifted one column to the left, and the far left column is removed.
