(14) Master constant voltage adjustment: adjusting master output
voltage.
(15) Fixed 5V output terminal (+): connecting the positive terminal of
load.
(16) Fixed 5V output terminal (-): connecting the negative terminal of
load.
(17) Master constant current adjustment: adjusting master output
current value (adjusting the current-limit protection point).
(18) Master output terminal (+): connecting the positive terminal of
load.
(19) Case ground: connecting the case to ground.
(20) Master output terminal (-): connecting the negative terminal of
load.
(21) Slave output terminal (+): connecting the positive terminal of
load.
(22) Case ground: connecting the case to ground.
(23) Slave output terminal (-): connecting the negative terminal of
load.
2.2 Operating method
2.2.1 Independence use of two adjustable output
2.2.1.1 Set (7) and (9) switch to spring out position.
2.2.1.2 When the adjustable output is used as CV output, first should
rotate clockwise the CC adjustment (2) and (17) to maximum, then
turn on power switch (13), adjust CV adjustment (4) and (14) till
output voltage reach required voltage value. At this time, the CC
state indicator (1) and (11) go out and the CV state indicator (3) and
(12) light on.
2.2.1.3 Used as CC output, after turning on power switch (13), first
rotate clockwise the CV adjustment (4) and (14) to maximum, while
rotate counterclockwise the CC adjustment (2) and (17) to minimum,
then connect the required load, again adjust clockwise adjustment
(2) and (17) till output current reach the required current value. At
this time, the CV state indicator (3) and (12) go out and the CC state
indicator (1) and (11) light on.
2.2.1.4 Used as the CV output, in general the CC adjustment (2) and
(17) should be set to maximum, but for this unit, the current-limiting
protection point can also be set arbitrarily.
