(1) CV Indicator Lights when the power is on and in constant voltage operation.
(2) CC Indicator Lights when in constant current operation.
(3) Voltage coarse For the coarse adjustment of the output voltage.
(4) Voltage fine For the fine adjustment of the output voltage.
(5) Current coarse For the coarse adjustment of the output current.
(6) Current fine For the fine adjustment of the output current.
(7) “+” output terminal Positive polarity (Red) (MAX. 3A output only).
(8) “GND” terminal Earth and chassis ground (Green).
(9) “–“output terminal Negative polarity (Black) (MAX. 3A output only).
(10) Meter Indicates the output voltage.
