Battery drawing power on AC
Power supply problem. Battery is showing current
draw while AC is connected.
Excessive noise on cell 1
Data rejection on cell 1 exceeds 90%, indicates
problem with cell or conductivity board.
Excessive noise on cell 2
Data rejection on cell 2 exceeds 90%, indicates
problem with cell or conductivity board.
Analog board communications
Unable to communicate with EEPROM on
conductivity board at power on. Check cable
connections between conductivity board and
system board. If problem persists, replace the
conductivity board.
Bad record encountered reading the system
constants file. Contact Technical Support or your
local service provider. The most likely cause is
unexpected power outage during write (Shutting

occurs frequently, this may indicate problems with
flash on the system board. You will need to
restore constants to correct the problem.
