5Adjust the knob for the desired output voltage.

Check that the Limit annunciator still flashes. Set the knob for voltage control. The second digit of the voltmeter will be flashing. Change the flashing digit using the resolution selection keys and adjust the knob to the desired output voltage.

6Return to the meter mode.

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

7Enable the output.

The OFF annunciator turns off and the 8V* (or 25V**) or 20V* (or 50V**), OVP, OCP and CV 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 voltage mode.

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

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