Subject:
SGP/EBBR/E8 - Battery Voltage Low
DataStreams:sgp30ebbrE8.b1, sgp15ebbrE8.b1, sgp5ebbrE8.b1
Description:
When Battery Voltage drops below 10.5 volts, most measurements are
suspect and some are often incorrect.  The user will need to inspect the
data carefully to determine the usability of the data.
Suggestions:
