rated value. Press  button, it will be lit. Now, there are three ways to set 
the voltage: 
Solution1:  press  button-------press  button  to  adjust  the 
cursor’s  position--------press  and  button  to  increase  or  decrease  the 
setting value. 
Solution2:  press button------press  button  to  adjust  the 
cursor’s position------adjust the knob to increase or decrease the setting value. 
Solution3:  press    button+  number    to    to  set  the  voltage 
value. Then press  button to confirm. 
3.4 Current setting   
IT6800A/B series  power  supply  enables customer  to  set current from 0V  to 
rated value. Press  button, it will be lit. Now, there are three ways to set 
the voltage: 
Solution1:  press  button-------press  button  to  adjust  the 
cursor’s  position--------press  and  button  to  increase  or  decrease  the 
setting value. 
Solution2:  press button------press  button  to  adjust  the 
cursor’s position------adjust the knob to increase or decrease the setting value. 
Solution3:  press    button+  number    to    to  set  the  voltage 
value. Then press  button to confirm.   
3.5 Output on/off 
  button is used to control the output of power supply. When 
button is lit, it represents output has been turned on. If    button is dark, 
it indicates that output is off. In output on mode, the indicator light CV or CC will 
be lit. 
Note: Please ensure the power supply and DUT has been connected well and 
then press  button to turn on the output. 
3.6 switch the actual/setting value display 
button is used to switch the display between actual and setting value. 
When  button is lit, it shows actual voltage and current on front panel. 
Meanwhile, VFD will appear a marker of “meter”. When  button is dark, 
it shows setting voltage and current on front panel. 
3.7 CC/CV mode 
According the ohm’s  law,  output current is determined by  output  voltage and 
the resistance of load. When actual current is less than the setting value, power 
supply will function in CV mode. And CV status indicator lamp will be lit. 
If actual current is  above the setting value or rated value,  power supply  will 
change to CC mode, and CC status indicator lamp will be lit.
