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 ann un ci at or is li t d ep en di ng on th e r e si st an ce of th e t es t l ea d. Th e 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).
Adju st the vo lta ge li mit to 1.0 vo lt t o a ssu re CC ope ra ti on. Th e 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).
