Learning Event 10:
EXTREMELY HIGH VOLTAGES, CAUSING DEATH ON CONTACT, ARE
CHECKS WITH POWER ON, USE JUST YOUR EYES, NOT YOUR
EXCEPT FOR SPECIFIC OUTPUT TESTS, MAKE ALL
TESTS WITH THE POWER OFF.
ALWAYS SHORT OUT HIGH
VOLTAGE CAPACITORS BEFORE TOUCHING THEM.
1. The reason you learned how a high-level modulator works is so you can
fix it when it goes bad. To do this job properly, you have to follow the
standard troubleshooting procedure.
Just going into the equipment
haphazardly wastes a lot of time.
Besides, it is extremely dangerous
practice because of high voltages present in the modulator and magnetron.
Actually, the modulator is just one unit within the radar system.
before you can hope to find a bad component in the modulator, you have to
determine first that the source of trouble is the modulator.
