(a) A3.8
5 percent ohms resistive load shall be applied between
ground-and the input pin (W1, P2-13) for a single, non-
10 millisecond period. The load pulse shall
repetitive 69
be initiated by application of an input voltage with a slope
not less than 5 v/millisecond to the input pin. Application
of the load pulse shall follow the input voltage rise by not
greater than one millisecond.
(b) The input pin is monitored for correct voltage in accordance
with the accept/reject limits specified in table III. The
accept/reject decision shall be made at a point 39
6
milliseconds after application of the resistive load pulse.
The input voltage accept/reject decision shall be latched
until reset by the PRESS TO READ DVM/RESET pushbutton or
changing the position of the FUNCTION SELECT switch.
(c) The input pin shall be monitored for the presence of voltage
in accordance with the limits of table III. The accept
criteria are met only when the latch of 3.4.5.2.b.(3)(b) is
set and voltage has subsequently been removed from the input
pin.
(4) Missile filament, W1, P2-22. The input pin shall be loaded by the
test set regulator load output amplifier circuitry. Current load
shall be not greater than 1.5 amperes.
(5) Regulator load, WI, P2-32.
(a) The test set output shall be an ac signal of 45
5 volts
ac amplitude at a frequency of 5,700
300 Hz.
(b) The load circuit shall be the tuned resonant circuit as
specified in Drawing 60A89C217.
(c) Capacitance to ground shall be not greater than 0.04
(6) Electrical cage, W1, P2-30. Continuity test to pin W1, P2-23,
electrical cage return. Accept/reject limits:
(a) Accept for greater than 90K ohms, reject for less than 8.OK
ohms.
(b) Accept/reject decision shall be updated at a one Hertz rate.
(7) Electrical cage return, W1, P2-23. Continuity test to pin W1,
P2-30, electrical cage as specified in 3.4.5.2.b(6).
(8) Motor fire squib, W1, aft striker contact.
(a) A 1.5 5 percent ohms resistive load, fused with a 1.5
ampere slow-blow fuse shall be continuously applied from
ground to the aft striker contact.
(b) The aft striker contact shall be continuously monitored for a
stray energy accept/reject decision in accordance with limits
of table VI. A reject decision shall be latched and displayed
