The following steps check basic current functions with a short across the power supply’s output.

1Turn on the power supply.

The power supply will go into the power-on / reset state; the output is disabled (the OFF annunciator turns on); the 15V/7A range is selected (the 15V annunciator turns on); and the knob is selected for voltage control.

2Connect a short across (+) and (-) output terminals with an insulated test lead.

3Enable the output.

Display Limit

Volt/Curr

The OFF annunciator turns off and the 15V, OVP, and OCP annunciators are lit. The CV or CC annunciator turns on depending on the resistance of the test lead. The blinking digit can be adjusted by turning the knob. Notice that the display is in the meter mode. ‘‘Meter mode’’ means that the display shows the actual output voltage and current.

4Adjust the voltage limit value to 1.0 volt.

Set the display to the limit mode (the Limit annunciator will be blinking). Adjust the voltage limit to 1.0 volt to assure CC operation. The CC annunciator will turn on.

5Check that the front-panel ammeter properly responds to knob control for the 15V/7A range.

Set the knob to the current control, and turn the knob clockwise or counter clockwise when the display is in the meter mode (the Limit annunciator is off). Check that the ammeter responds to knob control and the voltmeter indicates nearly zero (the voltmeter will show the voltage drop caused by the test lead).
