DO NOT enable this function for battery test applications (i.e. battery charging) and all
applications that may have a high charge. If a battery with a low voltage is connected to
the power supply while the output is OFF (disabled), the dummy load will drain the
battery. If the battery capacity is large and this function is enabled, a large current will
flow and damage the power supply and the dummy load.
To enable or disable this function, follow the steps below:
1. From the CONFIG menu, select Load and press .
2. Select between the two options:
Off – Disables the dummy load (default).
On – Enables the dummy load.
3. Select the desired option and press to save the change.
4. To exit the menu at any time, press twice.
