Battery Capacity
The LCD display has a battery bar for the battery life indicator. There are four levels
for the battery life. Three-bar means the maximum battery capacity and no bar (the
outline only) means the battery is almost exhausted. If only the outline is left, the
meter will be automatically turned off.
The backlight power consumption may make an apparent battery voltage drop when
the battery capacity is near only one bar. User may need to replace with a new battery
earlier if the backlight consistently used.
