The power supply will go into the power-on / reset state; all outputs are
disabled (the OFF annunciator turns on); the display is selected for the + 6V
supply (the +6V annunciator turns on); and the knob is selected for voltage
control.
2 Enable the outputs.
The
OFF

3 Check that the front-panel voltmeter properly responds to knob
control for the +6V supply.
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
