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 CC mode
and then press Enter key to enter test interface.
3. Rotate the rotary knob to change the current value (constant current value).
4. Press ON key to operating, press ON key again to stop the operation.

CV Voltage Test (Constant Voltage Test)
In CV mode, the electronic load maintains the input voltage as the set value by changing the current
consumption.
Select CV mode in mode interface, press Enter key to enter CV mode and input voltage 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.

CR Test (Constant Resistance Test)
In CR mode, the electronic load is equals to a resistance, linear change the current with the changing of
input voltage to maintain a constant resistance load.
Select CR mode in mode interface, press Enter key to enter CR mode and input resistance value;
Press ON key, the electronic load will load state and the indicator will be illuminated;
Press ON key again to stop the load and the indicator will be extinguished.
