The following procedures check to ensure that the power supply develops its rated outputs and properly responds to operation from the front panel. For complete performance and verification tests, refer to the Service Guide.

For each step, use the keys shown on the left margins.

Voltage Output Checkout

The following steps verify basic voltage functions with no load.

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.

2Enable the outputs.

The OFF annunciator turns off and the 15V, OVP, OCP, and CV annunciators are lit. 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.

3Check that the front-panel voltmeter properly responds to knob control for the 15V/7A range.

Turn the knob clockwise or counter clockwise to check that the voltmeter responds to knob control and the ammeter indicates nearly zero.

4Ensure that the voltage can be adjusted from zero to the full rated value. 1

Adjust the knob until the voltmeter indicates 0 volts and then adjust the knob until the voltmeter indicates ‘‘15.0 volts’’.

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