4.1.2 Constant Voltage Test
In CV mode, the electronic load changes current consumption to keep the input voltage as set value.
In the mode selection interface, select the CV mode, press Enter to enter the main operating interface,
and enter the voltage value in the main interface.Press the ON button, the electronic load starts to load,
and the indicator light lights up.If the users need to stop the load, press the ON button again, and the
indicator light goes out.
Figure 4-1-2 Relationship of Voltage and Current in CV Mode
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(HY8211/HY8213
single channel don’t need to choose.)
2. Press Mode key to enter the selection interface, use rotary knob or direction key to select CV mode
and then press Enter key to enter test interface.
3. Rotate the rotary knob to change the voltage value (constant voltage value).
4. Press ON key to operating, press ON key again to stop the operation.
4.1.3 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.
