Constant Current Operation

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

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

Display
Limit	6 Return to the meter mode.

Press key or let the display time-out after several seconds to return 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 CC 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 current mode.

If you operate the power supply in the constant current (CC) mode, verify that the CC annunciator is lit. If the CV annunciator is lit, choose a higher voltage limit.

N o t e	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.
•	Remote interface operation:
	VOLTage {<voltage>MINMAX}	Set the voltage
	CURRent {<current>MINMAX}	Set the current
	OUTPut ON	Enable the output
