Battery Option 300 is disabled 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? (query form)
- 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 disabled if the instrument is stored and unused for an
extended period. This will minimize battery drain.
Reading the Battery Level Pressing the Battery Level soft key or sending the
command:
SYSTem:BATTery:LEVel?
reads the battery charge (in percent) relative to a fully charged (100%) battery.
Battery in Use The presence and status (enabled or disabled) of the battery is
indicated by a battery icon in the upper-right corner of the display (Figure 1-2).
Remotely, the instrument can be queried as to whether it is currently using AC
power or battery power with the command:
SYSTem:BATTery:STATus?
The command returns AC if the instrument is using line power, or BATT if using the
internal battery.
