Like the E4418/4419B, the N1913/1914A also comes with a battery pack option,

allowing users to take measurements in remote areas where AC outlets are not

available. The battery pack used in the N1913/1914A is a smart-type battery

capable of communicating with the FPGA system and the smart battery’s

charger controller. The battery pack uses a system-level approach to optimize

the performance of the battery. There are additional safety features such as

protection from over-charging and over-discharging as well as passive safety

devices for short-circuit and thermal protection.

The new battery pack also has one-push-button activation with an LED indicator

(as shown in Figure 5) that displays information about battery capacity without

requiring the user to turn on the power meter.

The indicator is a four-level LED system, with each level representing different

battery power capacity as shown in Table 2.

For the single-channel N1913A, the operation duration of the battery pack

is 330 minutes with backlight off and 210 minutes with backlight on. The

maximum charging time of the battery pack is approximately two hours when

the N1913/1914A is in standby mode with the AC power connected.
