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.
Press the 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 the +25V supply or the
-25V supply, the +25V or -25V annunciator will turn on. 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.

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