Chapter 2 Quick Start

To use the power supply in constant voltage mode

5Adjust the knob for the desired current limit. 1

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.

6Adjust the knob for the desired output voltage. 1

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.

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.

8Verify 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 +25V supply or -25V supply, the +25V or -25Vannunciator will turn on. If the CC annunciator is lit, choose a higher current limit.

During actual CV operation, if a load change causes the current limit to be exceeded, the power supply will automatically crossover to constant current mode at the preset current limit and the output voltage 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.
