Table 35 Graphing Functions and Descriptions
Functions Description
Status Bar
Displays the time, date, measured value, and unit of measure at the intersection of the data cursor. Placing the
cursor’s data on the status bar eliminates the need for X or Y axis labels and provides a larger viewing area.
Moving the Data Cursor with the Arrow Keys
The data cursor appears as a vertical line in the center of the graph. Move the data cursor to the left or right by
using the soft keys or the numeric keypad.
Moving the Data Cursor with the Numeric Keypad
The keys 0–9 represent a percentage of full scale. Pressing a numeric key on the keypad while a graph is
displayed causes the data cursor to jump to the location on the graph that is represented by that key.
For example, pressing the 0 key moves the data cursor to the far left end or 0% position on the graph. Pressing
the 5 key moves the data cursor to the middle or 50% position of the graph. Pressing the 9 key moves the cursor
to the 90% position.
Next Channel Soft Key
Graphs data from the next logged channel. For example, if the 950 is logging Level, Flow, and pH and the Level
graph is currently displayed, the
NEXT CHANNEL
soft key causes the Flow channel to be graphed. Pressing Next
Channel again will create a graph for pH channel. Pressing
NEXT CHANNEL
again returns to the Level graph,
selects a time period of interest and compares different graphs.
