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.
