Pressing  zooms out, resulting in a graph whose time scale spans twice that of the previous view. This dou- bles the number of displayed samples.

Navigating a Zoomed View

While zoomed in on a graph, only a subset of the total number of samples are visible. To view samples that were recorded earlier or later than those in the current view, press the left and right cursor keys. The availability of ear- lier or later samples is indicated by the presence of arrows at either end of the X (time) axis.

12.12Low Battery Notifica-

tion

The E2 keeps track of how long the E2 battery has

been active, and will display a battery icon at the top of the E2 screen whenever the battery is reaching the end of its recommended battery life. If a battery has less than 30% of its battery life left, a yellow battery icon will appear at the top of the screen. If the battery has less than 10% life left, or if the battery switch is currently disabled, a red battery icon will appear.

For more information on battery testing and replace- ment, refer to Section 4.4, Battery Testing and Replace- ment.
