button, push    and  will enable you to adjust the setting current 
value. 
  The second way: press ,adjust cursor location through 
button, adjust rotary knob    to change the setting current value. 
  The third way: press    button and number key(   to  ) to set 
current value 
3.4 Output On/Off Operation 
  button is used to control the output state of power supply. When 
  button is lit, this indicates the output is in on mode. When output is 
open, the working state indicator light(CV/CC) will be lit. 
 
NOTE 
Make sure you have connected power supply and the test unit well, then press 
  button. If there is no voltage output, you should first check the voltage and 
current set. 
3.5 Setup value/Actual value switching 
You can switch the display between setting value and actual value by pressing
  button. When this button is lit, screen displays actual output value 
and the indicator light “Meter” will be lit on the VFD. In other words, when the 
button is not lit, the front panel displays setting value. 
3.6 Voltage/Current/Power adjustment 
The output current value is determined by output voltage of power supply and 
electronic load’s resistance. Only when the actual current value is lower than 
the setting current value, can power supply work in CV mode and the will CV 
indicator light be lit. 
If output current is higher than the setting value, then power supply will function 
in CC mode. And the CC indicator light will be lit. 
The output voltage and current value are also influenced by the upper limit of 
output power. 
Take IT6723H (300V/10A/850W) for example, suppose you set the voltage to 
100V, then the current can just reach 8.5A(limited by the power). 
3.7 Save/recall Operation 
Customer can save some often-used parameters in nonvolatile memory. You 
can use the button      (Shift)、 (Save) button or SCPI order *SAV、
*RCL to achieve this function. Saving parameters include: 
1.setting voltage 2.setting current 3. OVP value 4. OCP value   
Saving operation: 
Press  (Shift)+  (save) button( button will flash), and then 
input the group number you want to save through number key board. Press 
  button to confirm. 
Recall operating: 
Press    button ( button will lit), and press corresponding group
