Keysight 53147A/148A/149A Operating and Programming Guide
Overview
The Battery option (Option 002) allows you to operate the instrument 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
instrument when you are not using it, if an AC power source is available. (To
charge the batteries inside the instrument, it must be in Standby mode.)
Operating the Instrument from the Batteries
When the instrument 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. Whenever a battery-equipped
instrument is on (not in Standby), the battery annunciator in the lower-right
corner of the front-panel display (see
) 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.
Figure C-1
Battery Charge Level Indicator
When all three segments of the battery annunciator are activated, the battery
charge level is at 83% or more. When only two segments are activated, the charge
level is approximately 50%, and when only the first segment is activated, the
charge level is approximately 17%.
A pair of fully charged batteries in good condition provides enough power to
operate the instrument for approximately two hours at 25º C. Various conditions,
such as ambient temperature and the measurement configuration, can affect the
length of time the instrument can operate from a fully charged set of batteries.
