(4) Set FREQUENCY RANGE-Hz switch to 1 M and FREQUENCY dials to
1.0520 MHz.
(5) If frequency counter does not indicate between 1.0420 and 1.0620 MHz, adjust
A10C41 and A10C45 (fig. 1) in equal amounts in the same direction until frequency
counter indicates 1.0520 MHz (R).
(6) If true rms voltmeter does not indicate between 9 and 11 V, adjust A10C41 and
A10C45 (fig. 1) in equal amounts in opposite directions until true rms voltmeter indicates
10 V (R).
NOTE
Interaction exists between (5) and (6) above; repeat until the
indications converge.
(7) Set FREQUENCY RANGE-Hz switch to 100 K and FREQUENCY dials to
80.00 kHz.
(8) If frequency counter does not indicate between 79.6 and 80.4 kHz, adjust
A10C42 (fig. 1) for a counter indication of 80 kHz (R).
