Chapter 2 Quick Start
To use the power supply in constant current mode
32
5 Adjust the knob for the desired voltage limit.
1
Check that the knob is still selected for voltage control and the Lmt
annunciator blinks. Adjust the knob for the desired voltage limit.
6 Adjust the knob for the desired output current.
1
Set the knob for current control. The second digit of the ammeter will be
blinking. Adjust the knob to the desired current output.
7 Return to the meter mode.
Press the key or let the display time-out after several seconds
to return 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 current mode.
If you operate the +6V supply in the constant current (CC) mode, verify that
CC 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 CV
annunciator is lit, choose a higher voltage limit.
Note
During actual CC operation, if a load change causes the voltage limit to be
exceeded, the power supply will automatically crossover to constant voltage
mode at the preset voltage limit and the output current 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.
