Adjust 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.
6
Return to the meter mode.
Press the 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 outputs
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.
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
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 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.
