4.Turn on the power voltage indicator for battery voltage，On the limit pressure setting knob to rotate the pressure limiting regulating knob of the voltmeter instructions for the desired charging maximum limit pressure,General 12V lead-acid battery limit pressure setting is about 15V or depending on the specific request, when the charging voltage to the voltage limiting value when setting voltage no longer increases then the current is automatically reduced; if do not need to limit pressure can be adjusted to the maximum, but must be appropriately control the charging current and time, otherwise it will damage the battery overcharge.
5.
A slowly rotating current regulating knob of the ammeter indication for the desired charging current, charging current and time depending on the specific request, generally for the battery current ( ampere capacity 1/10 10 hour rate ) is appropriate, the charging time of about 15 hours, if the pressure is set correctly when the charging current is reduced to below 20% video electricity is sufficient.

4. Open power supply voltage meter instructions for the battery voltage, holding pressure limiting set button rotational limit pressure control knob make voltmeter instructions for the charging the highest pressure limiting, general 12 v lead-acid battery limit pressure set to 15 v or so or according to specific requirements and decide, when charging voltage to limit pressure setting voltage rise no longer the current automatic decreased; If you don't need to limit pressure can be adjusted to the largest, but must be properly control the charging current and time, otherwise will be charge and damage to the battery.

5. Slow rotation current regulation button make ammeter indication for the charging current, charging current and time depending on the specific request, generally for battery ampere hour capacity one over ten of the current (10 hour rate) is appropriate, full charging time about 15 hours, if the limit is set to the correct pressure when the charging current to below 20% can be regarded as electric has enough.
