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.
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.

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