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.

1You can use the resolution selection keys to move the blinking digit to the right or

left when setting the voltage and current.
