3.5.9.6 Computer system.
3.5.9.6.1 Computer self test.
a. The gunner's computer control unit mode selector switch shall cause all unit
malfunction lamps to illuminate, when placed in the LAMP position.
b. The mode selector switch shall cause only the green GO lamp to illuminate when
placed in the TEST position (see 4.6.4.9.6.1).
3.5.9.6.2 Common zero and zeroing (see 4.6.4.9.6.2).
a. Elevation. Rotation of the common zero and zeroing elevation knobs from zero to
3.0 mil, shall cause the output unit superelevation counter to change correspondingly
by 3.0 + 0.30 mil. Rotation of the knob back to zero shall cause the output unit
counter to return to the original setting within + 0.30 mil. This requirement shall
apply to both plus and minus adjustment directions.
b. Deflection. Rotation of the jump or zeroing deflection knobs, from zero to 3.0 mil,
shall cause the gunner's reticle to move correspondingly by 3.0 + 0.30 mil. Rotation
of the knob back to zero shall cause the reticle to return to the original zero setting
within + 0.30 mil. This requirement shall apply to both plus and minus adjustment
directions.
3.5.9.6.3 Ballistics solutions. The fire control system shall meet the requirements and
provide the ballistic solutions as specified in tables XI through XVII for the gunner's daylight
sight and for the commander's LRF sight. Solutions shall be measured as gun positional changes
from a reference zero. The reference zero shall be determined with the computer operating the
boresight mode at 1200 m range. The boresight range (1200 m) shall be inserted by means of the
battle range switch of the LRF in the test mode (see 4.6.4.9.6.3).
