(2)(9) Voltage display: Used to display the current voltage value of Circuit A (Circuit B), unit: volt (V).
(3)(11) Voltage Regulator Indicator C.V: When this lamp is on, it indicates that the power supply is in the state of stable voltage.
(4)(10) Steady current indicator C.C: When this lamp is on, it indicates that the power supply is in steady current state.
(5)(13) Steady current setting knob: used to set the current value of A (B) steady current state.Clockwise increase, counterclockwise decrease.
(6)(12) Stabilizer setting knob: used to set the voltage value of A channel (B channel) when the voltage is stabilized.Clockwise increase, counterclockwise decrease.
(7) power switch.
