Chapter 2 Quick Start

To Use the Power Supply in Constant Voltage Mode

5 Adjust the knob for the desired output voltage.

Check that the Limit annunciator still flashes. Set the knob for voltage control. The

second digit of the voltmeter will be flashing. Change the flashing digit using the

resolution selection keys and adjust the knob to the desired output voltage.

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.

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.

8 Verify 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.

Note 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.

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

left when setting the current.
