→Using a DC Power Supply
If you’ve done your calculations, you may not need to be as cautious with the current limiter, but it’s always a good idea to start low with the current limiter every time you are powering an untested circuit. Rarely will an insufficient current or voltage ever cause damage to analog or digital circuits. Granted, the circuit probably won’t function as expected with insufficient current/voltage, but it should be fine to slowly increase the current/voltage to the desired amount when you are first setting your DC power.

Set the current limiter above it’s minimum, and slowly increase the voltage to the desired amount. After you have set your voltage and current correctly, you don’t need to change the settings at this point. Simply turn on/off the DC power supply as needed with the power switch or the voltage knob. Do not disconnect the leads from your circuit while the power supply is still on; free-floating leads are a short-circuit risk. Disconnecting live wires is a bad habit that becomes extremely dangerous if you work with higher voltages due to arcing hazards.
