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
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
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.
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.
