Chapter 2 Quick Start

To use the power supply in constant current mode

5Adjust 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.

6Adjust 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.

7Return to the meter mode.

Press the Display Limit 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.

8Verify 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 -25Vannunciator will turn on. If the CV annunciator is lit, choose a higher voltage limit.

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.
