MAINTENANCE
3. Set the Right V/A switch to the A position.
4. Connect the external multimeter across the “A” SUPPLY
output terminals to read the output current (so that the meter
causes a short circuit across the terminals) and adjust the “A”
CURRENT control so that 2.00 amps is read on the “A”/4-
6.5V LED Display .
5. Adjust R163 ( “A” SUPPLY A METER ADJ ) so that the
1. Connect a 1 ? load (rated at 30W or more) and the
multimeter in series across the output terminals of the 4-
6.5V SUPPLY to read the output current.
2. Adjust the 4-6.5V voltage level control to obtain an
output of 5.30 amps (read on the multimeter).
3. Adjust R122 ( 4-6.5V A METER & A LIMIT ADJ ) so
that the “A”/4-6.5V LED Display also reads 5.30 amps.
multimeter also reads 2.00 amps.
4. Slowly Adjust

III. “B” SUPPLY AND METERING ADJUSTMENTS
5. Set the 0-30V/4-6.5V switch to the 4-6.5V position and the
Right V/A switch to the V position.
6. Connect an accurate (±0.1%) external 4-1/2 digit multimeter
across the output terminals of the 4-6.5V SUPPLY to read
output voltage and adjust the 4-6.5V front panel voltage level
control to minimum (4V, fully counterclockwise).
7. Adjust R134 ( 4-6.5V 3.9V REF ) located on the main board
for a reading of 3.90 volts on the external multimeter.
8. Adjust R133 ( 4-6.5V V METER ADJ ) located on the main
board so that the “A”/4-6.5V LED Display reads 3.90 volts.
9. Set the Right V/A switch to the A position.
10. Turn R122 ( 4-6.5V A METER & A LIMIT ADJ ) and
R159 ( 4-6.5V 6.8V REF ) located on the main board fully
clockwise.

1. Connect an accurate (±0.1%) external 4-1/2 digit
multimeter to measure the DC voltage at the output
terminals of the “B” SUPPLY .
2. Disengage the INDEP/TRACK mode switch (out) so
that the power supply is in the INDEP endent operating
mode.
3. Set the “B” VOLTAGE controls (both Coarse and
Fine ) to maximum (fully clockwise).
4. Adjust R10 ( “B” SUPPLY +5V REF ) on the main
board for as close to 30.70 volts (on the multimeter) as
possible.
5. Set the Left V/A switch to the V position.
6. Adjust R304 ( “B” SUPPLY V METER ADJ ) on the
“B” panel board (located on the left side of the supply
behind the “B” LED Display ) for a reading of 30.7
volts on the “B” LED Display .
