Operation steps:
1. In initial interface, select [Mode], and then press [CV] to enter the setting interface of
<Constant Voltage CV>.
2. Move the cursor to voltage setting by pulse knob, and press the Enter button to
change the voltage value (the value changes from yellow to white) by keyboard or
pulse knob. Press the Enter button again to confirm. At this time, the set voltage
value changes from white to yellow.
3. Other parameters can be modified in a similar way.
