2.2. Safety Guidelines
• Before plugging into local AC mains, check and make
sure that the output voltage is compatible to the load. (It
is suggested to disconnect a load before plugging into
local AC mains.
• Do not use this instrument near water.
• Do not operate or touch this instrument with wet hands.
• Do not open the casing of the instrument when it is
connected to AC mains.
• The max.output voltage of the instrument may be over
60VDC, avoid touch the metal contact part of the output
terminals.

• Do not use the instrument in an atmosphere which
contains sulfuric acid mist or other substances which
cause corrosion to metal.
• Do not use the instrument in a dusty place or a highly
humid place as such will cause instrument reliability
degradation and instrument failures.
• Install the instrument in a place where is free from
vibration.
• Install the instrument in a place where the ambient
temperature is in range of 10~70°C. Note that the
instrument operation may become unstable if it is
operated in an ambient temperature exceeding the range
of 0~40°C
2.3. Power Supply
AC Input voltage: 110V~120V/220~240V ±10%, 50/60Hz.
Connect the protective grounding conductor of the AC power
cord to an earth ground to avoid electrical shock.
2.4. Fuse
• Make sure the correct type of fuse is installed before
power up.
• Replace the AC fuse with the same type and rating as
the original fuse.
• Disconnect the power cord before fuse replacement.
• Make sure the cause of fuse blowout is fixed before
fuse replacement.
2.5. Cleaning
• Before cleaning, disconnect the AC mains.
• To clean the power supply, use a soft cloth dampened in
a solution of mild detergent and water. Do not spray
cleaner directly onto the instrument, since it may leak
into the cabinet and cause damage.
• Do not use chemicals containing benzene, benzene,
toluene, xylene, acetone, or similar solvents.
• Do not use abrasive cleaners on any portion of the
instrument.
2.6. Operation notes

4. Operation Instructions
4.1. Basic Operations
• The applied Voltage/Current Unit for this series
instruments is Volt and Amp.
• The factory setting is in panel operation mode that
enable user to operate the instruments directly from
panel control knob. Besides, when the remote controller
is on line, the Lock key light turns on and the operation
can only be proceed through it. At this time, all the
panel operations are closed unless the key [Lock] is
pressed, but the Output is still working. Whenever the
power is reset, the output will be at OFF status and the
operation is through front panel operation mode.
• When users operate the power supply with dual range,
during the switch process, the output is at OFF
automatically. And if the original setting value is more
than the maximum output range after switch, the setting
value will be modified automatically to the maximum
output value after switch
• When the Output key light turns on, the CV or CC
indicator at the right side of the LCD represents the
instrument is in the CV or CC mode and the LCD
displays the output measurement value.
• The output of power supplies is always at OFF status
after power on.
5. Numeric Keypad Input
If an option is selected, you can input the parameters by us-
ing the numeric keys. There are ten numeric keys for data
input. The input method is the shift input from right to left.

The data can have only one decimal point. If one data input
has more than one decimal point, only the first one is valid.
After input a new value, press key [Enter] to validate it. If
the input data has error, there are three ways to correct it.
Method 1: If the destination side of output signal can receive
the wrong signal, press key [Enter] to terminate the current
operation. Input the correct data, and press the key [Enter]
to validate the input.
Method 2: If the destination side of output signal can not
receive the wrong signal, the wrong input is not validated
because of no any wrong signal at the output. Reselect the
operation, input correct data, and press the key [Enter] to
validate the input.
Method 3: Press keys [Shift] [Enter], then input the correct
data, and press the key [Enter] to validate the input.
6. Step Key Input
In practices, a set of voltage or current value with same inter-
val is commonly used. It is complicated and time consuming
to input this kind of data by repeatedly pressing the numeric
keypad and Enter key. It is also complex by using the rotary
knob because voltage or current value may be multi-digit.
It is very convenient to use the step input method. Every
pressing the corresponding soft key can make the voltage or
current increase or decrease by a step value. The modified
data is validated automatically without pressing the Enter
key.
For example, to generate a series of voltage with interval
1.1V, press the keys sequentially as following:
Press keys [Shift] [Menu] to enter function setting interface,
Press key [Menu] again until “Utility V Step” is shown on
the LCD,
Press keys [1] [.] [1] [Enter] to complete step voltage value
setup,
Press key [V-Set/I-Set] again until “Voltage” is shown on
the LCD,
Press keys [Shift] [<] to increase the voltage by 1.1V or
press keys [Shift] [>] to decrease the voltage by 1.1V. Re-
peat this operation, a series of voltage with equal interval
can be generated. The same procedure can be used for the
current operation.
7. Knob Adjustment
In some applications, it requires to adjust the output signal
continuously. Using the rotary knob can complete this task.
Press key [<] or [>] to move the cursor left or right. Rotate
the knob to the right to continuously increase the cursor-lo-
cated digit by 1 and make the carry to a higher unit position.
Rotate the knob to the left to continuously decrease the cur-
sor-located digit by 1 and make the carry to a lower unit
position. When you use the knob to modify a specified data,
the modified data is validated instantaneously without press-
ing the Enter key. A coarse adjustment is made by moving
the cursor to the left; and a fine adjustment is made by mov-
ing the cursor to the right.
