5Adjust the knob for the desired output voltage. 1
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.
6Return 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.
7Enable the output.
The OFF annunciator turns off and the 15V or 30V, 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 45 for more
information on OVP and OCP annunciators.
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.
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.
• Remote interface operation:
CURRent {<current>|MIN|MAX} Set the current

OUTPut ON Enable the output
1You can use the resolution selection keys to move the blinking digit to the
right or left when setting voltage.
