NOTE
Do not perform power supply check if all other parameters are
within tolerance.
a. Performance Check
(1) Connect multimeter to TP1046 (+15V) test point (fig. 2) and chassis ground.
Multimeter will indicate between +14.84 and +15.13 V.
(2) Repeat technique of (1) above for supply voltages at test points listed in table 11.
If an out-of-tolerance condition is noted, perform b below.
