increased to 126.5
2.0 volts AC, the QUALITY meter shall indicate on the
center of the line which determines the right edge of the triangle zone. The
input resistance at J101-C shall be 230
15 ohms.
3.5.1.1.7 TEST switch position 4 (heater voltage interlock). An input
voltage of 104.0
1.0 volts AC, 400
20 Hz applied to J101-B shall cause the
QUALITY meter to indicate on the center of the line which determines the left
edge of the triangle zone. When the input voltage at J101-B is increased to
126.5
2.0 volts AC, the QUALITY meter shall indicate on the center of the
line which determines the right edge of the triangle zone. The current into
J101-B shall be 0.60
0.20 amperes for any input voltage from 103.5 to 126.5
volts AC.
3.5.1.1.8 TEST switch position 5 (target direction indicator foresight).
With 115
11.5 volts Ac, 400
20 Hz applied to J101-B, the QUALITY meter
shall indicate in the circle zone. The headtone output shall be present as
specified in 3.5.1.2.3 and the direction finder outputs shall be in accordance
with table II.
3.5.1.1.9 TEST switch position 6 (target direction indicator left). With
115
11.5 volts AC, 400
20 Hz applied to J101-B, the QUALITY meter shall
indicate in the circle zone. The headtone output shall be present as speci-
fied in 3.5.1.2.3 and the direction finder outputs shall be in accordance with
table II.
3.5.1.1.10 TEST switch position 7 (target direction indication down).
With 115
11.5 volts AC, 400
20 Hz applied to J101-B, the QUALITY meter
shall indicate in the circle zone. The headtone output shall be present as
specified in 3.5.1.2.3 and the direction finder outputs shall be in accordance
with table II.
3.5.1.1.11 TEST switch position 8 (fire sequence). With 115
11.5 volts
AC, 400
20 Hz applied to J101-B, the headtone output and the QUALITY meter
indication shall be in accordance with table III with 28
2 volts DC applied
to J101-Z, the input resistance at J101-H shall be 25
2.5 ohms.
