3) Set the current limit value:
Press [I SET], the panel operation is set to current value input
mode, set the desired change value by using the number key or
the wheel knobs (the wheel knob can be used together with [<] or
[>] to adjust the resolution).
4) Set the desired output voltage value:
Press [V SET], the panel operation is set to voltage value input
