Display and user interface 
the first rows of LED display charger output voltage.
Second row after turning digital, will estimate the battery voltage level voltage according to the display. After charging starts, it will display the current charging current.
from left to right are four buttons "Query", "level (+)", "start (-)", "Settings."
Query: Press Search button, the first row of the fourth digit LED will show "A", "b", "0", the second row corresponds to digital will show "charge into the electricity," "the current internal temperature "," Battery Percentage. "
Grade (+): not performed before charging, this key will be forced to change the battery rating, the second row displays the corresponding voltage level. Inexperienced users with caution.
Start (-): When the voltage level changed, press to force start charging, the charger according to the set voltage level for charging, the wrong choice may damage the battery voltage. Inexperienced users with caution.
Setting: Press, allows the user to enter the setting mode, and the second rows of LED displays "AH", "U", "A", "dA", "db", "dC", respectively "battery capacity "," highest constant "," turning the current, "" reduced flow coefficient "," high timing "," full timing. "
1, the first charger output plug into the electric vehicle charging mouth, and then connected to the mains.
2, set the Setup button, AH and must adapt to a nominal capacity of electric vehicle batteries. Recommendations 20AH battery with a current of about 2A charging, setting a value of 12-15 AH. (If you do not know the settings, please consult the relevant technical staff and customer service.)
3, continue to press the Set button, the parameter corresponding to U4, A3, dA2, db4, dC12, press the Set button to return to the initial state, charger will automatically save user settings.
4, the new user is recommended to use only 36/48 automatic recognition, charger after the completion of the identification, automatic charging.
5, the main charge is completed, the first row of the fourth decimal digit LED flashing into floating state, according to the charging process turn lights confirmed at the highest pressure limiting nearby, then the fan stops, reducing the flow into the float.
6, post float, there will regularly appear pulse, oxygen evolution were stepping pulse to the beginning of sulfur, targeted, the effect is significant.
7, the pulse ends, the current at about 0.1A to maintain the battery is in adequate condition.
(User steps 2 and 3, the next charge will automatically save your settings, steps 2 and 3 do not need to make.)
