Output check
The output check includes a voltage check under no load through all channels; additionally it
checks for short circuits, this is to ensure the instrument correctly functions.
1. Voltage output check
(1) Within no load, turn on the power, and make sure the current setting of all channels is not
zero.
(2) Turn on CH1/CH2 and set the instrument to constant voltage mode. Check whether the
voltage value could be changed from 0V to 32V.
2. Current output check
(1) Turn on the power, and make sure the current setting of all channels are not zero.
(2) Use an insulated wire to connect the positive and negative terminal of CH1/CH2.
(3) Turn on CH1/CH2 and set instrument to constant current mode. Check whether the
current value could be changed from 0A to 3.2A.

2.1 Output summary
The power supply has three independent outputs, two of which have adjustable voltage and
the other one includes selectable 2.5V, 3.3V or 5.0V
Independent/Parallel/Series
The power supply has three output modes: independent、parallel and series, which can be
selected through the track switch on the front panel. In the independent mode, the output
current and voltage are controlled respectively. In the parallel mode, the current value is
twice that of the single channel. In the series mode, the voltage value is twice that of the
single channel.
Constant voltage/current
In the constant current mode (independent or tracking mode), the current value is rated and
controlled through the front panel. Voltage value is under rating. The indicator light displays
red. It will return to constant voltage mode when the current value is under rated.
In the constant voltage mode, the current value is less than the setting value, and the voltage
value is controlled through the front panel. The current value is maintained at the set value,
the indicator light displays yellow. It will return to constant current mode when the voltage
value is under rated.

18
2.3 CH3 Independent mode
Instruction
CH3 is independent from CH1 and CH2, and it works neither in parallel mode nor in series
mode. Its voltage and current ratings are respectively 2.5V, 3.3V, 5V and 3.2A.
Output ratings 2.5V/3.3V/5V, 3.2A
Operation steps:
1. Connect the load to the positive and negative terminals of CH3 on the front panel.
2. Select the required voltage value by moving CH3 “DIP switch”.
3. Turn on the output:
Press “on/off”button to turn on the output, the corresponding indicator light gets lit
immediately.
When the current value is higher than 3.2A, the overload indicator light turns red and the
working mode turns to CC from CV
Note: “overload” does not mean abnormal operation.

19
2.4 CH1/CH2 Series mode
Instruction
In the series mode, CH1 and CH2 are linked internally into one channel which
is controlled by CH1, and the output voltage value is twice compared with that of single
channel.
Output rating 0~64V/0~3.2A
Operation steps：
1. Press the “Ser” button to start the Series mode, the indicator light turns bright
immediately and the logo “”displays at the top of screen.
2. Connect the load to the positive terminal of CH2 and the negative terminal of CH1.
3. Set voltage and current value:
a) Press “1”button to select the channel 1
b) Move the cursor through direction button to select the required parameter(voltage,
current),
c) Press “Fine” to select the digit position and then revolve the multi-function knob to
change the corresponding parameter.
4. Press “on/off”button corresponding CH1 to turn on the output
Note: You can identify the current working state “CC”or ”CV”by referring to indicator
light of CH1/CH2.(red means CV, yellow means CC)

20
2.5 CH1/CH2 Parallel mode
Instruction
In the parallel mode, CH1 and CH2 are linked internally into one channel which is controlled
by CH1. Its output current value is twice as much as the single channel.
Output rating 0~32V/0~6.4A
Operation steps:
1. Press the “Para”button to start Parallel mode, the indicator light turns bright immediately
and the logo “”display at the top of screen.
2. Connect the load to the positive and negative terminal of CH1.
3. Set voltage and current value:
a) Press “1”button to select the channel 1
b) Move the cursor through direction button to select the required parameter(voltage,
current),
c) Press “Fine” to select the digit position and then revolve the multi-function knob to
change the corresponding parameter.
4. Press “on/off”button corresponding CH1 to turn on the output
Note: You can identify the current working state “CC”or “CV”by referring to indicator light of
CH1/CH2.(red means CV, green means CC).
In parallel mode, CH2 only works in CC mode.
