4.Disconnect the shorting lead from the output terminals. The power supply will now automatically switch into current limiting mode (current regulation) as soon as the preset current level is reached.

To operate the supply in CI mode:

1.Set the current limit as described above.

2.Set the voltage control fully clockwise or to the compliance voltage of the circuit.

As soon as the supply starts operating in current mode, the red current mode LED will turn on.

The automatic crossover system allows the power supply to automatically switch operating modes in response to changing load requirements. For example, if the load current attempts to increase above the setting of the current adjust control, the unit will switch automatically from Constant Voltage to Constant Current mode. If you lower the load requirements, the supply will automatically return to Constant Voltage mode.
