The optional ML2400A Series Power Meter battery is a 12 Volt, 3000
mA-h nickel-metal hydride (Ni-MH) multi-cell pack, located in a com-
partment on the bottom of the housing. The compartment cover is se-
cured by fractional turn fasteners, as shown in Figure 2-1. Rotate the
fasteners approximately ¼-turn counterclockwise to release the cover.
NOTE
The battery is shipped with a partial charge only, and
should be fully charged before use.
The battery can be completely charged in about two hours with the
power meter in standby mode by selecting CHARGE from the System
menu (page 4-31). This selection is available only when the instru-
ment is being powered by AC line power or external DC power greater
than 21 volts. Note that the instrument will shut down during the
charging cycle, and restart automatically when the charging is com-
pleted. A series of 10 beeps signals completion of the charge cycle.
