Basic Operation

The normal power source for the Energy Platform is its internal battery pack. The AC 

Adapter/Battery Charger is used to charge the battery. Always charge the battery fully 

before use. The Energy Platform will always operate on the charger and is designed to 

do so, regardless of the state of charge of the battery. 

Type: Sealed, rechargeable NiMH (Nickel Metal Hydride) cells. 

Length of operation: The Energy Platform 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. 

Charging: The battery pack can be charged by connecting the AC Adapter/Battery 

Charger to the Energy Platform. 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 Energy Platform can be operated from a 50/60 Hz 120/230V AC power source 

with or without the battery pack installed.

Connect the AC Adapter output cable to the Input Connector on the right side of the 

Energy Platform. Connect the AC Adapter power cord to an appropriate outlet. 

Refer to Appendix C for the specifications and replacement of the batteries contained 

in Energy Platform.
