The Charged Parameters
Your Meter depends on the Charged Parameters to stay in sync with the battery
state-of-charge, to automatically reset to Zero, and to automatically calculate the
CEF. The default settings are for 12V lead acid (liquid or gelled) batteries. They
have been carefully chosen to work on most systems, including constant voltage
and multiple step charging systems.
The factory Charged Parameters are 13.2 Volts and 2% of battery capacity as a
charged current. (2% of the default battery capacity of 200 Ahr equals 4 Amps).
Several conditions must be met for a recalcualtion of the CEF and a reset to Zero:
First 100% of the energy removed from the battery must be returned, additionally
the battery must be above 13.2 Volts and the current must fall below 4 Amps, for
five minutes, when all these conditions are met the battery is considered full.
CAUTION: If your battery voltage is other than 12V you MUST set up an
appropriate Charged Voltage.
If the charged parameters are not set correctly,
Your Meter will never recalculate the CEF!
Please consider changing only the battery capacity unless your system falls into
one of the following categories:
1)
Battery chemistry other than lead acid.
12 Volt NiCad (and NiFe) systems would normally use 15.5 to 15.7 as the
Charged Voltage. See your battery specifications for guidance. The
Charged Current % can probably stay at 2% of declared battery capacity.
2)
Charging normally ends before current drops below 2%.
If the charging system is normally shut down before charging current drops
below 2%, the Charged Current % will have to be changed.
