20.Power Supply

NOTE

Do not perform power supply check if all other parameters are within tolerance.

a.Performance Check

(1)Connect multimeter INPUT HI to -15 V TP (fig. 5) and LO to ground side of C9 (fig. 5). Adjust R22 (fig. 5) for a multimeter indication of -14.97 to -15.03 V dc (R).

(2)Connect multimeter INPUT HI to +15 V TP (fig. 5). Readjust R22 (fig. 5) if multimeter does not indicate between 14.9 and 15.1 V dc.

(3)Connect multimeter INPUT HI to +5 V TP (fig. 5). Readjust R22 (fig. 5) if multimeter does not indicate between 5.01 and 5.05 V dc.

(4)Repeat (1) through (3) above for best in-tolerance condition on all test points.
