(53) Press oscilloscope ERASE pushbutton then press Autostore pushbutton to
STORE.
(54) Set control box PWR switch to ON and press LAMP TEST pushbutton.
NOTE
Oscilloscope trigger level may need to be readjusted to view the
small amplitude waveform.
(55) Measure MODE 4 (DIFF) pulse width. If pulse width is not between 0.4 and 0.6
s, perform b (4) below.
b. Adjustments
(1) Adjust A3R32 (fig. 7) for a SUM pulse width between 0.7 and 0.9 s (R).
(2) Adjust A3R34 (fig. 7) for a DIFF pulse width between 0.7 and 0.9 s (R).
NOTE
MODES 1, 2, 3, and C have common adjustments A3R32 for
SUM pulses and A3R34 for DIFF pulses. (Adjust these
resistors for best compromise.)
(3) Adjust A3R33 (fig. 7) for a pulse width between 0.4 and 0.6 s (R).
(4) Adjust A3R35 (fig. 7) for a pulse width between 0.4 and 0.6 s (R).
