Operating Instruction
Setting Voltage Current
Inthe operation interface, short press to enter the setting voltage and
currentinterface. The bottom of LCD screen displays SET and CV flashing, short
press!:‘pr potentiometer knob to switch voltage selection, adjust the set
voltage through rotating the knob.
Press Aagain, the bottom of LCD screen displays SET and SW flashing, short.
pressFor potentiometer knob to switch current selection, adjust the set
current through rotating the knob. Short press again to save setting and exit
to the working interface. Long press for 2 seconds or wait for 6 seconds
without any operation, the system will automatically save the setting and exit
to the working interface.
Quick Set Voltage Current
Inthe parameter setting interface, set “FET” to CV or CC. Rotate the potentiometer knob in working interface, then enter the voltage current setting interface. Rotate the potentiometer knob again to quick set the voltage or current.
Setting Parameter
3.1 In the working interface, long press for 2 seconds to enter the parameter
setting interface.
3.2 Press to switch the parameter to be set, short press the potentiometer
knob to switch selection, rotate the potentiometer to adjust value.
3.3 In the OAH/OPH/OHP interface, short press to turn on/off OAH/OPH/OHP.
3.4 In the OAH/OPH interface, long press to choose measure range
(9.999AH/99.99AH/999.9AH/9999AH; 9.99WH/99.99WH/999.9WH/9999WH)
3.5 After parameter setting is completed, long press SW for 2 seconds to save
the parameter and exit.
Display Input/Output Voltage
Check Power(W)/Capacity(AH)/Energy(WH)/Time(H):
In the working interface, short press
potentiometer knobto switch the display Power
(W)/Capacity(AH)/Energy(WH)/Time(H)
Lock Function
In the working interface, long press the potentiometer for 2 seconds tolock the setvoltage and current. Then long press the potentiometer for 2 seconds again to unlock.
Other Function
7.1 Capacity/Energy/Working Time:
The Capacity/Energy/Working Time will be automatically measured after power
ON. After power OFF, the measurement will be temporarily stopped until next
time turn ON. In the corresponding interface, long press will clear the data.
7.2 Set the maximum Capacity(OAH)/maximum Energy(OPH)/maximum working
time(OHP)
7.2.1 Set OAH/OPH: OAH/OPH turn ON, when measured capacity/energy are higher
than the set maximum capacity/energy, output will automatically turn off and
flash “OAH”/“OPH”. After the alarm is lifted, data will be automatically
cleared.
7.2.2 Set the maximum working time(OHP): OHP turn ON, when working time is
higher than the maximum working time, output will automatically turn off and
flash “OHP”. After the alarm is lifted, data will be automatically cleared.
These functions can achieve a regular and quantitative power supply.
Note: if OAP/OPH/OHP are off, the meter will also record the
capacity/energy/working time. After OHP is on, the working time will display
as countdown mode.
