2.3. Operating method
1. When the adjustable output is used as CV output, first should rotate clockwise the CC
adjustment (11) to maximum, then turn on power switch (7), adjust CV adjustment (4) and (5)
till output voltage reach required voltage value, at this time, the CC state indicator (12) or (14)
go out the CV state indicator (6) or (13) light on.
2. Used as CC output, after turning on power switch (7), first rotate clockwise the CV adjustment
(4) and (5) to maximum, while rotate counterclockwise the CC adjustment (11) to minimum,
connect the required load, again adjust clockwise adjustment (11) till output current reach the
required current value. At this time, the CV state indicator (6) or (13) go out and the CC
state indicator (12) or (14) light on.
3. Used as the CV output, in general the CC adjustment (11) should be set to maximum, but for
these units, the current-limiting protection point can also be set arbitrarily.
Setting procedure: turn on power, rotate counterclockwise the CC adjustment (11) to minimum,
then make the positive and negative output terminal in short connection and rotate clockwise
the CC adjustment (11) till output current equal to the required current-limiting protection point,
so the current-limiting protection point is well set, disconnect the short connection.
3. Caution
These units have excellent protection function. The adjustable output have current-limit protection.
As there is controlling circuit for regulating transistor’s power loss in the circuit, when short-circuit
occurs, the power loss on large power transistors is not very high, it can’t cause any damage to
the unit. But there is still power loss when short-circuit, in order to reduce aging and energy
consumption, so this situation should be find as soon as possible and turn off power, then exclude
the faults.
When operating is finished, put it in a dry place of good ventilation, and keep it clean. If it is not in
use for a long period, pull off the power supply plug for storage.
For maintenance, input voltage must be cut off.

This manual is according the latest technical knowing. Technical changings which are in the
interest of progress, reserved.
We herewith confirm that the units are calibrated by the factory according to the specifications as
per the technical specifications.
We recommend to calibrate the unit again, after 1 year.
