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.
N o t e
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.
