Calibrating and Adjusting
To adjust the power supply

If the +5.1 V measurement is out of tolerance, adjust the
+5.1 V / -5.2 V balance adjustment on the power supply. See Figure 4-2.
5 If the -5.2 V measurement is out of tolerance, adjust the
+5.1 V / -5.2 V balance adjustment on the power supply. See Figure 4-2.
The +15.75 V supply is not adjustable, and is dependent upon the +5.1 V supply.
