If the +5.1 V measurement is out of tolerance, adjust the +5.1 V adjustment
on the power supply; if the –5.25 V measurement is out of tolerance, adjust
the –5.25 V adjustment on the power supply (see figure below). The ±15.75
V supplies are not adjustable and are dependent upon the +5.1 V supply. If
adjusting the power supply does not bring all the voltages within tolerance,
see "Troubleshooting the Oscilloscope," on page 4-32 in this chapter.
