Appendix C Using the Battery Option

Overview

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 (Agilent P/N 53150-60217).

Operating the Counter from the Batteries

When the Counter is powered from the internal batteries, it operates in the same manner as it does when it is powered from an external AC or DC source, except that the cooling fan does not operate, and the Main AC Power On LED is not lit. Whenever a battery-equipped Counter is on (not in Standby), the battery annunciator in the lower-right corner of the front-panel display (see Figure C-1) indicates the approximate charge level remaining in the batteries. This allows you to estimate the amount of time you can continue to operate from battery power before recharging the batteries or replacing them with fully charged batteries.
