2. Move the cursor to the needed setting position by pulse knob, and press the Enter
button to change the parameter (the parameter changes from yellow to white)
by keyboard or pulse knob. Press the Enter button
the set value changes from white to yellow.
3. Other parameters can be modified in a similar way.
4. Press the ON button, the electronic load starts to load, and the indicator light below
the button lights up. If users need to stop the load, press the ON button again, and the

4.2.7 Load Effect

The load effect mode can carry out loading under 3 different load conditions (10%, 50%,
and 100%), and continue the load for a preset time (5s), and then record the voltage
under different loads. Finally, calculate the load regulation rate, △V and other values
according to the formula.
Parameter setting in load effect mode:
Rate voltage
Rate current
Formula: Vmax=Vdc@Imin, Vmin=Vdc@Imax, △V=Vmax-Vmin, Regulation=△V/Vset
Before the load effect test, input the rated voltage and rated current, and then press ON to
enter the test. At this time, the load will be loaded according to 3 different loads in turn,
