(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.
