9. OPERATION PROCEDURES
– DUAL TYPE
9.1 Constant Voltage Setting Method
1) Turn on power switch.
2) Adjust voltage setting knob to the desired voltage which can be
shown in the LCD display.
3) Connect the load, make sure the load current not exceeding the
maximum output current.
9.2 Constant Current Adjustment Method
1.Adjust by turning the voltage setting knob to desired voltage.
2. Press the CV/CC setting button down to light up the CC/CV setting
indicator.
3. Use a wire to shorten the (+) and (-) terminal at output terminal.
4. Push the UP or DOWN button to obtain the current value.
5. When pushing and hold the UP or DOWN button over 0.8 sec, the
value will go up or go down continuously.
6. Release the shortend wire, connect the load to begin operation.
7. The setting of current value will be stored in the EEPROM after off.
8. The current value will be resumed by pushing the CV/CC button
when next power on.
