5. Enabling the outputs
Press the “Output on/off” key to enable the outputs. “CV” is displayed in the lower right corner of the display.
6. Verifying that the power supply is in the constant voltage mode
When you operate the power supply in the constant voltage (CV) mode, if “CC” is displayed in the lower left corner of the
display, it indicates that the actual output current value has reached the set value. Therefore please choose a higher current
limit value.
3.4 Constant Current Output Setting
When the power supply is in constant current mode, the current will output at a constant value, and it will not change with the
load while the voltage will. The CC annunciator in the lower right corner of the display will turn on when the power supply is in
constant current mode. The operation methods of constant current output are introduced in the following.
1. Connecting a load to the relevant output terminals
Turn off the power supply. Connect the load to the relevant terminals. Connect the positive pole of the load to “+” terminal of
the output, and connect the negative pole to “-” terminal of the output.
2. Turning on the power supply
Press the “Power on/off” button in the front panel. The power supply will go into power-on/ reset state, namely the power
supply is off.
3. Maximum output voltage setting
Maximum output voltage can be set directly by pressing number keys or using “Left/Right” key together with the knob.
1). Using number keys and “Enter” key to enter:
① Press “Vset” to enter into voltage setting state.
② Enter the desired voltage value by pressing number keys. “Clear” key can be used to clear the wrong value.
③ Press “Enter” key to confirm the voltage setting value.
2). Using “Left/Right” keys, knob and “Enter” key to enter:
① Press “Vset” to enter into voltage setting state.
② Press “Left/Right” keys to move the blinking digit to the corresponding digit of the value.
③ Increase or decrease the relevant value by turning the knob clockwise or counter clockwise, then use “Left/Right” keys to
move to the next digit to modify.
④ Press “Enter” key to confirm the voltage setting value.
4. Setting the desired output current
The desired current can be set directly by pressing the number keys or using “Left/Right” keys together with the knob.
1). Using number keys and “Enter” key to enter:
① Press “Iset” to enter into current setting state.
② Enter the desired current value by pressing number keys. “Clear” key can be used to clear the wrong value.
③ Press “Enter” key to confirm the current setting value.
