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

6Return to the meter mode.

Press DisplayLimit 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 output.

The OFF annunciator turns off and the 8V* (or 25V**) or 20V* (or 50V**), 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 the 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.
