5 Adjust the knob for the desired output voltage.
Check that the Limit annunciator still flashes. Set the knob for voltage control.
Change the flashing digit using the resolution selection keys and adjust the
knob for the desired output voltage.
6 Return to the meter mode.
Press 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 CV annunciator turns on. Notice that
the display is in the meter mode.
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.
