CE-1008
(3) Adjust potentiometer R5 on the Control Indicator until the needle on the BEAM WIDTH meter is at zero.
(4) Position and hold the beam width change switch, S7, to the BEAM INCREASE position until the feed is
fully extended (as reported by personnel in the radome).
(5) Adjust potentiometer R6 on the Control Indicator until the needle on the BEAM WIDTH meter is at 100.
(6) Repeat steps (2) through (5) until optimum deflection of the needle on the BEAM WIDTH meter is obtained
in either direction.
D. CABLE WRAP ADJUSTMENT
(1) Operate the equipment in accordance with the procedures contained in paragraph 4.A of this section.
(2) Rotate the azimuth handwheel CCW to 90 degrees (-270 degrees limit). The needle on the CABLE WRAP
meter, M1, should deflect in a decreasing direction toward its left red limit marking.
(3) Adjust potentiometer R7 on the Control Indicator until the needle on the CABLE WRAP meter just enters
the left red limit marking.
(4) Rotate the azimuth handwheel CW to 270 degrees. The needle on the CABLE WRAP meter, M1, should
deflect in an increasing direction toward its right red limit marking.
(5) Adjust potentiometer R8 on the Control Indicator until the needle on the CABLE WRAP meter first enters
the right red limit marking.
(6) Repeat steps (2) through (5) until optimum deflection of the needle on the CABLE WRAP meter is
obtained in either direction.
E. SECTOR SCAN ADJUSTMENT
(1) Operate the equipment in accordance with the procedures contained in paragraph 4.A of this section.
(2) Perform the sector scan procedures contained in paragraph 4.D of this section.
(3) If, when scanning a sector, the angle scanned is not equal on either side of 000. 0 degree, within 5
degrees, deenergize the equipment and perform the following procedures:
