4.3 Battery Status Indicators
The PROLOGGER measures its internal battery voltage every scan. If the
battery voltage falls below certain preset levels, the Battery Status LEDs on
the front panel will change state.
GREEN RED BATTERY STATUS ALKN NiCAD LCD DISPLAY
ON OFF Battery OK >7.2V >7.2V OK
ON ON Battery Low (Replace soon) <7.2V <7.2V Low
OFF ON
Battery Flat (Replace
immediately)
<6.6V <7.1V Chg
OFF OFF Not Operating (“Sleep” or
“Shutdown” Mode)
<6.2V <7.0V Bad
Whenever an external power source greater than 11V DC is connected to the
logger, the internal battery is bypassed (and/or recharged). The logger
operates from the external power, but will automatically use the internal
battery if external power falls below 11V DC or fails altogether.
4.4 Monitoring Battery Voltage
The most recent battery voltage measurement is stored in the logger memory
and can be displayed or logged.
The PROLOGGER saves the voltage measurement at Address 236 (Internal
Channel I2, also called, “Batt”, see page 32). Use Test Mode to display the
internal channels.
4.5 Flat Battery Shutdown
The logger also monitors the battery voltage when in
sleep mode
. If the
voltage falls to a level that could cause faulty operation, the logger enters
shutdown
state and will not scan, communicate with a computer or activate
the display. In addition, all equipment power loads are disconnected (counter
channels and pin 18 continuous power) to preserve memory.
The Flat Battery Shutdown voltage limit is 5.6V.
