6. Initial parameter set up
When you are willing to alter the parameter value in the program, press Start/Enter key to make it blink then change the value with
INC or DEC key. The value will be stored by pressing Start/Enter key once.
This informs you of its designation.
The screen displays the nominal voltage of Lithium battery. There are three kinds of Lithium
battery; LiFe(3.3V),Lilo(3.6V) or LiPo(3.7V). This is very important so you have to check the battery
carefully and set it up correctly. If it is different from correct value the battery can explode during
charge process.
It recognise the cell count of Lithium battery automatically at the beginning of charge or discharge
process to avoid from erroneous setting by user. But deeply discharged battery can be perceived
incorrectly. To prevent the error, you can set the time term to verify the cell count by the processor.
Normally, 10 minutes are enough to perceive the cell count correctly. For the battery of larger
capacity, you may extend the time term. But if you set the time term too long for the battery of
smaller capacity, the charge or discharge process can be
finished within the time term with the
erroneous cell count. This may cause the fatal result. If the processor recognises the cell count
incorrectly at the beginning of charge or discharge process, you may extend the time. Otherwise,
you had better use with the default value.
This shows the trigger voltage for automatic charge termination of NiMH and NiCd battery. The
effective value ranges from 5 to 20mV per cell .if the trigger voltage is set higher, there is a danger
of overcharging the battery; if it is set lower, there is a possibility of premature termination. Please
refer the technical specification of the batter y.(NiCd default:12mV/cell, NiMH default:7mV/cell)
