Output Checkout
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.
1 Turn on the power supply.
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 annunciator turns off and the +6V 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.
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 rated value.
Adjust the knob until the voltmeter indicates 0 volts and then adjust the knob until
the voltmeter indicates 6.0 volts.

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