To check the rated currents of the power supply
The following procedures check to ensure that the power supply develops its rated
current outputs with a short and properly responds to operation from the front panel.
For each step, use the keys shown on the left margin.
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 Connect a short across (+) and (-) output terminals of +6V supply with an
insulated test lead.
3 Enable the outputs.
The OFF annunciator turns off and the +6V annunciator turns on. The CV or CC
annunciator is lit 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.
4 Adjust the voltage limit value to 1.0 volt.
Set the display to the limit mode (the Lmt annunciator will be blinking). Adjust the
voltage limit to 1.0 volt to assure CC operation. The CC annunciator will light.
5 Check that the front-panel ammeter properly responds to knob control for the
+6V supply.
Set the knob to the current control, and turn the knob clockwise or counter clockwise
when the display is in the meter mode (the Lmt annunciator is off). Check that the
ammeter responds to knob control and the voltmeter indicates nearly zero (actually,
the voltmeter will show the voltage drop caused by the test lead).
