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 the following figure). 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" in this chapter.
