I somehow didn't understand your example. Given the measurement parameters, you set the voltage to 2.00V and the resistance to 3.3OHM, the limiting current should be around 0.61A. But in the demo you don't assume that the power supply really limits the current when it exceeds 0.61A, the current limit setting knob is still at some value and you are only manipulating the voltage. I thought that the example should show that the source correctly limits the current when the calculated value is exceeded. I guess I didn't understand the example correctly.
