5 Adjust the knob for the desired output voltage.
Check that the
Limit annunciator still blinks. Set the knob for voltage control.
The second digit of the voltmeter will be blinking. Change the blinking digit
using the resolution selection keys and adjust the knob to the desired output
voltage.
6 Return to the meter mode.
Press 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.
7 Enable 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.
Refer to “Programming Overvoltage Protection” and “Programming
Overcurrent Protection” sections, starting on page 42 and page 46 for more
information on
OVP and OCP annunciators.
8 Verify 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.
Note 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.

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