The following steps check basic current functions with a short across the appropriate
supply's output.
1 Turn on the power supply.
Power
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 the +6V supply with an
insulated test lead.
Output On/Off
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
Display Limit
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
Vol/Cur
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).
