124 Keysight 53150A/151A/152A Operating Guide
Overview
The Battery option (Option 002) allows you to operate the Counter away from a
source of AC power using internal rechargeable batteries or the external DC (EXT
DC) power connector on the rear panel. You can charge the batteries inside the
Counter when you are not using it, if an AC power source is available. (To charge
the batteries inside the Counter, it must be in Standby mode.) You can also
charge the batteries outside the Counter using an AC or suitable DC power source
and the optional External Charger (Keysight P/N 53150-60217).
