If commercial power is not available when the AC adapter is connected, the
LR8400-20, LR8401-20, LR8402-20 Memory HiLogger can operate from the Model
Z1000 Battery Pack, so
when using commercial power, the battery pack serves as a backup supply during
power outages.
Charge the battery pack fully before using it the first time.
Be sure to read "Using the Battery Pack" (p .8) before installing.
Required items: phillips screwdriver (M3), Hioki Z1000 Battery Pack
