System Statistics—Battery Screen
The Battery screen displays several kinds of information:
• Temperature—the internal temperature of each battery as measured by a sensor
embedded in each battery
• Voltage—for each battery cell stack as measured by each battery’s sensor
• Run Time to Empty—while using external power, External DC Power is
displayed; while using battery power, the predicted remaining battery run time is
displayed in minutes at the present rate of discharge. If two batteries are
installed, the second battery will have Not in Use displayed. The instrument
mode you select affects the discharge rate, which determines the run time to
empty. Antenna/Cable, Spectrum Analyzer, CDMA Tx Analyzer, and CDMA
Over Air modes use the most power. Backhaul and Power Meter modes use the
least power.
• Fuel Gauge Error—the present accuracy of each battery’s fuel gauge or
remaining charge capacity. If the error exceeds 10%, you should condition the
battery.
• Percent Charged—the predicted charge capacity of each battery in percent.
• Battery Status—For Battery 1 and Battery 2, Present or Missing tells you
whether a battery is installed.
Built-In Battery Gauge
Each Lithium Ion battery has a five-segment LCD gauge that displays its charge
% displayed beneath
