CH1/CH2 Series Mode 

Instruction: 

In the series mode, CH1 and CH2 are linked internally into one channel controlled 

by CH1. The output voltage value is twice compared with that of single channel. 

 

 

 

Output ratings 

0~60V/ 0~3.2A 

 

Operation steps

 

1. 

Press the 

  to start the Series mode, and the indicator light turns bright 

2. 

Connect the load to the positive terminal of CH2 and the negative terminal of CH1; 

3. 

Turn  on  CH1  and  set  its  current  value  to  3.2A.  In  the  default  setup,  the  instrument  works  in 

“Coarse”, you can turn to “Fine” by pressing 

  ; 

Coarse: 0.1V or 0.1A each step; 

Fine: the least precision each step; 

4. 

Turn on CH1and set the output voltage/current value by revolving the multi-function knob; 

5. 

Press 

  button to open the output. 

 

Note:

 You can identify the current working state “CC” or “CV” by referring to the indicator light.(red 

means CV, green means CC)
