1 Preparation for Use
Enabling and disabling the battery
When using the instrument with the Battery Option 300 for the first time after
purchase, or if the instrument has not been used for an extended period, the
battery must be charged before use. With line power connected and the
instrument either on or off, allow four hours for the battery to reach full charge.
Battery Option 300 is d isabled when the instrument is shipped from the factory.
Battery control (enable/disable) is provided by the front panel keys shown on the
previous page or using the command:
SYSTem:BATTery:ENABle {OFF|ON}
SYSTem:BATTery:ENABle?
- ON enables the battery. Off disables the battery. The battery state is stored in
non-volatile memory and does not change when power is cycled or following a
reset (*RST) or instrument preset (SYSTem:PREset or Preset key).
The battery should remain enabled while the counter is using AC power. The
battery should only be d isabled if the instrument is stored and unused for an
extended period. This will minimize battery drain.
Reading the battery level
command:
SYSTem:BATTery:LEVel?
reads the battery charge (in percent) relative to a fully charged (100%) battery.

Remotely, the instrument can be queried as to whether it is currently using AC
power or battery power with the command:

internal battery.
