Battery power explained
The battery check screen is used to determine the battery/power status of the
instrument. When operating on batteries, the grey area in each cell graphic
indicates the charge on each cell (Figure 2-5).
When operating on an external power source (see next section, “external
power sources”), the external power will take precedence over batteries if
installed.
