5 Adjust the knob for the desired current limit.
Check that the Lmt annunciator still blinks. Set the knob for current control.
The second digit of ammeter will be blinking. Adjust the knob to the desired
current limit.
6 Adjust the knob for the desired output voltage.
Set the knob for voltage control. The second digit of the voltmeter will be
blinking. Adjust the knob to the desired output voltage.
7 Return to the meter mode.
“Display Limit” key or let the display time-out after several seconds to return to
the meter mode. Notice that the Lmt annunciator turns off and the display
returns to the meter mode. In the meter mode, the display shows the actual
output voltage and current of the selected supply.
8 Verify that the power supply is in the constant voltage mode.
If you operate the +6V supply in the constant voltage (CV) mode, verify that CV
and +6V annunciators are lit. If you operate the power supply for +25V supply
or –25V supply, the +25V or –25V annunciator will turn on. If the CC
annunciator is lit, choose a higher current limit.

You can use the resolution selection keys to move the blinking digit to the right or left when setting
the voltage and current.
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.
