System Set-Up
It will be operated with the default value of the essential user settings when it is connected to a DC 11~18V
battery at the first time. The screen displays the below information in sequence and the user can change the
value of parameter on each screen. Press START/ ENTER button to make it blink then change the value by
press Dec. or Inc. button. The value will be stored by press START/ENTER button again.

The battery is on the cyclic process of charge and discharge
can often become warm after charge or discharge period.
The program can insert a time delay to occur after each charge
and discharge process to allow the battery adequate time to cool
down before being subjected to the next process.
The value ranges from 1 to 60 minutes. When you start a charge
process, the integral safety time automatically starts running at
the same time. This is programmed to prevent overcharge the
battery if it proves to be faulty, or if the termination circuit cannot
detect the battery full. The value for the safety time should be
generous enough to allow a full charge of the battery.
Safety time Calculation
When charging NiMH or NiCD batteries, divide the capacity by
current, then divide the result by 11.9, set this number as the
value for safety time setting. If the charger stopped at this
threshold, about 140% of the capacity will have been fed into
the battery
Capacity Current Safety Time
2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes
3300mAh 3.0A (3300/3.0=1100)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes
