5Adjust the knob for the desired output current. 1

Check that the Limit annunciator still blinks. Set the knob for current control. The second digit of the ammeter will be blinking. Change the blinking digit using the resolution selection keys and adjust adjust the knob to the desired output current.

6Return to the meter mode.

Press the Display Limit key or let the display time-out after several seconds to return the meter mode. Notice that the Limit annunciator turns off and the display shows "OUTPUT OFF" message.

7Enable the outputs.

The OFF annunciator turns off and the 15V or 30V, OVP, OCP, and CC annunciators are lit. Notice that the display is in the meter mode. In the meter mode, the display shows the actual output voltage and current.

8Verify that the power supply is in the constant current mode.

If you operate the power supply in the constant current (CC) mode, verify that CC annunciator is lit. If the CV annunciator is lit, choose a higher voltage limit.

During actual CC operation, if a load change causes the voltage limit to be exceeded, the power supply will automatically crossover to constant voltage mode at the preset voltage limit and the output current will drop proportionately.

1You can use the resolution selection keys to move the blinking digit to the right or left when setting the voltage and current.
