Operation steps   
1.

 

After the instrument is boot-up, press CH key to select the channel, yellow wireframe area is the 
selected channel and it will display the prompt of CH1 or CH2 at top of the screen ( single 
channel don’t need to choose.) 

2.    Press Mode key to enter the selection interface, use rotary knob or direction key to select CR mode 

and then press Enter key to enter test interface. 

3.    Rotate the rotary knob to change the resistance value (constant resistance value). 
4.    Press ON key to operating, press ON key again to stop the operation.

CP

 

Test (Constant Power Test)

 

In CP mode, the electronic load consumes a fixed power and the instrument will adjust the current with 
the changing of voltage to maintain a constant power. 
Select CP mode in mode interface, press Enter key to enter CP mode and input power value; 
Press ON key, the electronic load will in load state and the indicator will be illuminated; 
Press ON key again to stop the load and the indicator will be extinguished.
