NOTE
Do not perform power supply check if all other parameters are
within tolerance.
a. Performance Check
(1) Connect digital voltmeter to +3V (C3) test point (fig. 6) and chassis ground. If
digital voltmeter does not indicate between +2.95 and +3.05 V dc, perform b (1) below.
(2) Move positive lead to +15.7V (C2) test point (fig. 6). If digital voltmeter does not
indicate between +15.5 and +15.9 V dc, perform b (2) below.
b. Adjustments
(1) Adjust A1 R1 (fig. 6) for a 3.00 V dc indication on digital voltmeter (R).
(2) Adjust A1 R15 (fig. 6) for a 15.70 V dc indication on digital voltmeter (R).
