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.
