III The method for use
1. The method for use
(1) Power-on: check the input voltage whether it is normal voltage value or
not.
(2) Clockwise regulate the constant-current setting knob (6) to the maximum.
Place the power switch in “ON” position, the indicator light is on.
(3) Constant voltage setting: the knobs (6) should be clockwise regulated to
the maximum. Regulate the voltage regulation knobs (8) to set the necessary
voltage value, and then connect the load to the “+” and “-” output terminal. At
this moment the power supply is working under the condition of constant
voltage, the output voltage remains the same, while the output current changes
