LESSON
LEVEL RADAR, ADJUST POWER SUPPLY AND CENTER CURRENT, AND SYNCHRONIZE
PRECISION SWEEP
TASK
Describe the leveling of the AN/FPN-40 radar set group and the adjustment of
power supply voltages of the PP-1670, synchronizer generator SN-836, and the
10 kW power supply PP-607. Describe the adjustment of the 1500 CPS voltage
and the centering current. Identify the alignment procedures for the angle
volts demodulator and the azimuth angle data resolver.
CONDITIONS
Given this subcourse, pencil, and paper.
STANDARD
The standard is met when the student demonstrates competency of task skills
and knowledge by correctly responding to 70 percent of the multiple-choice
questions on the final examination.
Learning Event 1:
LEVEL RADAR SET
1.
Learning Event 1 will enable you to locate and operate the leg
leveling jacks, to interpret spirit levels, and to level the AN/FPN-40 radar
set group. The radar set AN/FPN-40 is leveled to ensure the proper accuracy
of the clinometers.
