5. Initial Parameter set up (Users' set up)
It will be operated with the default value of the essential user settings when it is
connected to a DC 11~18V batttery for the first time.The screen displays the following
information in sequence and the user can change the value of parameter on each
screen.
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.

User set up starting screen.
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 nished 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 battery.(NiCd default:12mV, NiMH
default:7mV)
