Constant Voltage Operation

Voltage	1
Current	5 Adjust the knob for the desired output voltage.

Check that the Limit annunciator still blinks. Set the knob for voltage control. The second digit of the voltmeter will be blinking. Change the blinking digit using the resolution selection keys and adjust the knob to the desired output voltage.

Display
Limit	6 Return to the meter mode.

Press key or let the display time-out after several seconds to return to the meter mode. Notice that the Limit annunciator turns off and the display shows “OUTPUT OFF” message.

Output
On/Off	7 Enable the output.

The OFF annunciator turns off and the 8V* (or 25V**) or 20V* (or 50V**), OVP, OCP and CV annunciators are lit. Notice that the display is in the meter mode. In the meter mode, the display shows the actual output voltage and current.

Refer to “Programming Overvoltage Protection” and “Programming Overcurrent Protection” sections, starting on page 42 and page 46 for more information on OVP and OCP annunciators.

8Verify that the power supply is in the constant voltage mode.

If you operate the power supply in the constant voltage (CV) mode, verify that the CV annunciator is lit. 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.
•	Remote interface operation:
	CURRent {<current>MINMAX}	Set the current
	VOLTage {<voltage>MINMAX}	Set the voltage
	OUTPut ON	Enable the output

1You can use the resolution selection keys to move the blinking digit to the right or left when setting voltage.
