Chart Cursor (10)
If the user wishes to know the value at any at a particular data point on the chart, the cursor can be
used. The cursor is activated by pressing the ( - ) key on the keypad and is represented by a vertical
line on the chart. The cursor can be moved left or right by the ( - ) or ( + ) key respectively. This cursor
location now represents the current data point value of interest. The cursor will stay with the chosen
data point and move with the updating chart. When the cursor finally hits the end of the chart it
deactivates and the current data point value will now be the latest data point entering the chart.

Pressing the ( + ) button will move the cursor to the
