Instructions:
Left Key:  Energy-saving mode,can turn on or turn off the digital tube display
Right Key: Toggle digital tube display mode,input voltage→output voltage→current→power→alternate display
Setting voltage: Pressure right key switch to output voltage display mode,then adjust the voltage potentiometer to adjust the voltage.
Setting current: Switch to display A mode,short connection the output terminal,red and blue indicator light on,then adjust the current potentiometer to adjust the current.
Setting example: Charge for 3.7V/3800mAh lithium battery.Make sure the charge voltage is 4.2V,charging current is 1.5A,then press right key switch to output voltage display mode,adjust the voltage potentiometer to get 4.2V,
then press right key switch to current display mode,short connection the output terminal,adjust the current potentiometer to get 1.5A,then it is okay.
Correction function:
Under the output voltage/current display mode,long press the right key for 3 seconds,then the tube blink,press the left key and right key to adjust the value.It need to press for more many times then the valve will change.
LM358 Dual Operational Amplifier:
LM358 is dual operational amplifier,the internal consists of two independent operational amplifiers with high gain and internal frequency compensation.Suitable for wide voltage range of single power supply,also suitable for suitable for dual power supply operation modes.Under recommended operating conditions, the supply current is independent of the supply voltage.
1.Internal frequency compensation
2.High dc voltage gain(about 100dB)
3.Unit gain band width
(about 1MHz)
4.Slew rate(0.3V/us)
5.low power consumption current,suitable for battery power supply
