SWE EM1 UPDATED ACTUAL QUESTIONS AND
CORRECT ANSWERS
Question:
The currents in the FI and QI degaussing coils must be?
Answer:
The currents in the FI and QI degaussing coils must be changed when there are
changes in the ships heading, magnetic latitude, or both.
Question:
The proper polarity must be observed when applying
what?
Answer:
Proper polarity must be observed when applying/adjusting coil currents in the
degaussing systems.
Question:
An automatic degaussing system takes signals from the
gyro system and converts into what?
Answer:
An automatic degaussing system takes signals from the gyro system and converts
them into signals proportional to the magnetic heading.
Question:
When megging degaussing coils that have rectifiers for
power supplies you must always?
Answer:
When megging degaussing coils that have rectifiers for power supplies, always
disconnect the rectifiers.
Question:
When megging a degaussing coil for grounds you must
always?
Answer:
When megging a degaussing coil for grounds, open the supply switch and tag the
reversing switch.
Question:
The ship's gyro system provides the automatic
degaussing system with what?
Answer:
The ship's gyro system provides the automatic degaussing system with a synchro
signal.
Question:
, What does the degaussing system signal amplifier circuit
send to the relay amplifier?
Answer:
The degaussing system signal amplifier circuit sends the relay amplifier a dc
output signal.
Question:
Degaussing coil insulation resistance should be measured
by?
Answer:
Degaussing coil insulation resistance should be measured IAW navships tech
manual.
Question:
When a ship is said to be ranged when its magnetic field
is measured at a magnetic range, is known as?
Answer:
A ship is said to be ranged when its magnetic field is measured at a magnetic
range, known as degaussing station.
Question:
manually, automatically
Answer:
Control of coil currents is accomplished manually in older degaussing installations
and automatically in new ones.
Question:
Degaussing installations with rheostat control are
supplied by what?
Answer:
Degaussing installations with rheostat control are supplied by a constant dc
generator.
Question:
When megging a degaussing switchboard you should?
Answer:
When megging a degaussing switchboard, open the main breaker and close the
reversing switch
Question:
Shipboard winches are normally designed to withstand a
static load of what?
Answer:
Shipboard winches are normally designed to withstand a static load of 200% of
rated load without distortion.
Question:
