3.2. PREPARING FOR USE
Appliance location
The temperature of environment must not be higher than
40°C and the relative humidity should be less than 80%.
Ensure good ventilation in the room in which the device
is being used. There should be at least 10 cm distance
between each side of the device and the wall or other
objects. Keep the device away from hot surfaces. Operate
the device on an even, stable, clean, fire-proof and dry
surface and out of the reach of children and persons with
mental disabilities. Position the device such that you always
have access to the power plug. The power cord connected
to the appliance must be properly grounded and
correspond to the technical details on the product label.
3.3. DEVICE USE
Using the device
1. Front control panel:
1.1. The voltage / current units used on this device are
Volt (V) and Ampere (A).
1.2. In the factory settings mode of the panel, the user
can operate the device directly using the panel rotary
knob.
1.3. When the remote control of the device is connected,
the [Lock] button is engaged automatically, and the
control can only be carried out remotely. The "On /
Off" button is still available for use. All other buttons
are locked. To unlock the control panel, press the
[Lock] button, the button backlight will turn off.
1.4. The device is off after it is connected to a power
source.
2. Entering numerical values:
2.1. Numeric buttons:
Use the 0 to 9 and comma buttons to enter the target
values, then press the [Enter] button to confirm. If
the set value is incorrect, press the [Cancel] button
to clear the current value and enter the correct one.
(Number entry: 32.000 V is [3] [2] [.] [0] [0], 3.200A is
[3] [.] [2] [0] [0]).
2.2. Rotary knob
When continuous adjustment of the output signal is
required, it is recommended to use the adjustment
rotary knob. To do this, press the [<] or [>] button
to move the cursor left or right. Turn the rotary knob
clockwise to increase the number continuously.
Turn it anticlockwise to decrease the number. The
modified value is immediately confirmed without
pressing the [Enter] button.].
3. Setting the output voltage:
Press the [Voltage] button, the voltage cursor flashes.
Enter the target value (the rotary knob) or enter and
accept the target value (the numeric buttons).
4. Setting the output current
Press the [Current] button, the output current cursor
starts flashing.
5. Over voltage protection (O.V.P):
The overvoltage protection function protects the
power supply pack and the test object against
damage caused by excessive voltage.
Before starting the test, enable the O.V.P. function
and set its value. When the output voltage exceeds
EN
that value, the power will be turned off and the
display will show "O.V.P".
With the O.V.P function enabled, the output voltage
is limited by the O.V.P. range. To avoid damage to
the power supply pack, the O.V.P. range can not
exceed 120% of the rated voltage.
When the device goes into O.V.P mode, first of all
remove the causes, then turn on the power again.
5.1. Setting O.V.P value: Press [O.V.P. Level], the O.V.P.P.
cursor starts flashing. Enter the target value (the
rotary knob) or enter and accept the target value (the
numeric buttons).
5.2. Setting O.V.P. status
Press [O.V.P. Status] to turn the O.V.P. function on or
off.
6. Overcurrent protection (O.C.P):
The overcurrent protection function protects the
power supply and the object being tested against
damage caused by conductive current.
Before starting the test, enable the O.C.P. function
and set its value. When the output current exceeds
that value, the power will be turned off and the O.C.P.
message will appear on the display. When the O.C.P
function is enabled, the output current is limited by
the set O.C.P range.
6.1. Setting O.C.P value
Press [O.C.P. Level], the O.C.P cursor flashes. Enter
the target value (the rotary knob) or enter and accept
the target value (the numeric buttons).
6.2. Setting O.C.P status
Press [O.C.P Status], to enable or disable the O.C.P.
function.
7. Setting the output flow delay:
Keep pressing the [Menu] button until "PARAME
DELAY" appears on the display. Enter the target value
(the rotary knob) or enter and accept the target value
(the numeric buttons) in seconds.
8. Function settings:

appears on the display. All settings are set to default
factory settings. The factory settings can be turned
on or off using the rotary knob.
Keep pressing the [Menu] button until "Utility LAST"
appears on the display. The current settings become
start-up settings when the device is turned on. Turn
the factory setting on or off with the rotary knob.
ON: After switching off the device, the last settings
used will be remembered.
OFF: The output settings will be default ones.
8.2. Setting the OP relationships:
Press the [Menu] button until "OP LIM" appears on
the display. Set the O.V.P and O.C.P relationship with
voltage and current. Use the rotary knob to turn the
relationship setting on or off.
ON: When the O.V.P value is set to ON; the input
voltage maximum value is O.V.P.
When O.C.P is "ON", the maximum input current
value is O.C.P.
OFF: O.V.P and O.C.P are not associated with voltage
and current.
8.3. Setting the RS232 baud rate:
Keep pressing the [Menu] button until "Utility Baud"
appears on the display. Change the baud rate code
using the numeric buttons or the rotary knob. Make
sure that the baud rate meets the requirements of
the computer's remote control. The following table
shows the corresponding baud rate code:

8.10. Utility sensing settings
When the external receiver draws high current, the
voltage on the cable connecting the power supply
and the load will drop. In the constant voltage
mode, the remote sensing function automatically
compensates for the voltage drop across the
connecting cable. Before using the function, make
sure that the power is in remote sensing mode and
that the device is turned off. Do not connect the
sensor cable to the load connecting cable.
To enable or disable the remote sensing function,
keep pressing the [Menu] key until "Utility Sens"
appears on the display. Use the rotary knob to turn
the function on or off.
