To Check the Rated Voltages of the Power Supply
The following procedures check to ensure that the power supply produces its
rated voltage output with no load and properly responds to operation from the
front panel.
For each step, use the keys shown on the left margins.
1 Turn 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 8V/20A* or 25V/7A** range is selected (the
8V* or 25V** annunciator turns on); and the knob is selected for voltage control.
2 Enable the outputs.
The
OFF annunciator turns off and the 8V* or 25V**, OVP, OCP, and CV
annunciators are lit. The flashing 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.
3 Check that the front-panel voltmeter properly responds to knob
control.
Turn the knob clockwise or counter clockwise to check that the voltmeter
responds to knob control and the ammeter indicates nearly zero.
4 Ensure that the voltage can be adjusted from zero to the maximum
rated value.
Adjust the knob until the voltmeter indicates 0 volts and then adjust the knob
until the voltmeter indicates ‘‘8.0 volts’’* or ‘‘25.0 volts’’**.

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