Introduction
The normal power source for the PowerVisa is its internal battery pack. The AC
Adapter/Battery Charger is used to charge the battery. Always charge the battery fully
before use. The PowerVisa will always operate on the charger and is designed to do so,
regardless of the state of charge of the battery.
Battery pack
Type: Sealed, rechargeable NiMH (Nickel Metal Hydride) cells.
Length of operation: The PowerVisa can operate on a fully charged battery pack for
more than two (2) hours with the backlight on. When the backlight is turned off, the
unit can operate for more than three (3) hours. For information on how to turn backlight
on or off, see Chapter 4 Instrument Settings - Set Display Preferences on page 4-6.
Charging: The battery pack can be charged by connecting the AC Adapter/Battery
Charger to the PowerVisa. A screen warning will appear during operation when battery
charge is low. A depleted battery pack can be recharged in six (6) hours whether the
unit is on or off. The Battery Charge Indicator glows steadily while charging, and
flashes when fully charged.
NOTE: The Battery Charge Indicator functions whenever the AC Adapter/Battery
Charger is properly connected.

The PowerVisa can be operated from a 50/60 Hz 120/230V AC power source with or
