2. OPERATION
2.1 Controls and description of front-panel
(1) Meter or LED: indicates master output voltage and current value.
(4) Meter or LED: indicates slave output voltage and current value.
(5) Slave constant voltage adjustment: adjust slave output voltage value.
(6) Slave constant current adjustment: adjust slave output current value (adjust the current-limiting
protection point).
(7) Power switch: It is set to “ON” state(the switch is pressed in), the unit is switched on, at this time,
the constant voltage (C.V.) or constant current (C.C.)
indicator is on, otherwise, the unit is in “OFF”
state (the switch is sprung out).
(8) Slave constant current state or two-way parallel state indicator: When slave output is in constant
current state or the two adjustable is in parallel, this indicator is on.
(9) Slave constant voltage indicator: When slave output is in constant voltage state, this indicator is on.
(10) Slave output negative binding post: Negative polarity of output voltage is connected to negative
terminal of load.
(11) Case grounded terminal: The case is connected to the earth.
(12) Slave output positive binding post: positive polarity of output voltage is connected to positive
terminal of load.
(13/14) The control switch for selecting the two adjustable outputs independent, series or parallel.
(15) Master output negative binding post: Negative polarity of output voltage is connected to negative
terminal of load.
(16) Case grounded terminal: The case is connected to the earth.
(17) Master output positive binding post: Positive polarity of output voltage is connected to positive
terminal of load.
(18) Master output constant current state indicator: When master output is in constant current state,
this indicator is on.
(19) Master output constant voltage state indicator: When master output power is in constant voltage
state, this indicator is on.
(20) Fixed 5V DC output negative binding post: Negative polarity of output voltage is connected to
negative terminal of load.
(21) Fixed 5V DC output positive binding post: Positive polarity of output voltage is connected to
positive terminal of load.
(22) Master output constant current adjustment: Adjust master output current value. (Adjust current-
limiting protection point)
(23) Master output constant voltage adjustment: Adjust master output voltage value.
