4. Press the Zoom button again to return to the regular trend graph.
Minimum axis time in zoom mode is 120 seconds. If you wish to use the zoom

red to indicate that the read line mode is active, and black vertical line will
appear at the current time position on the graph.
2. To move the line to a time of your choosing, press the graph at the desired
point. You can also press the Read Line <<< or >>> button (both are now
red and active) to move the line one click at a time for more precision (
