AMTEC AMT1022 ADVANCED TECHNOLOGIES EXAM
STUDY GUIDE & QUESTIONS 2026/2027 COMPLETE
WITH 100% VERIFIED ANSWERS
Question 1: What is the primary goal of predictive maintenance
(PdM)?
A. To perform maintenance at fixed time intervals
B. To repair equipment only after it breaks down
C. To perform maintenance based on the actual condition of the
equipment
D. To reduce the initial cost of new equipment
CORRECT ANSWER: C
Rationale: Predictive maintenance uses condition monitoring tools to
determine when maintenance is needed, avoiding unnecessary
scheduled tasks and preventing unexpected failures.
Question 2: When analyzing machine vibration, what does a high
amplitude at 1x RPM typically indicate?
A. Misalignment
B. Unbalance
C. Looseness
D. Bearing defect
CORRECT ANSWER: B
Rationale: A dominant peak at 1x running speed is the classic signature
of rotor unbalance in rotating machinery.
,Question 3: What is the primary purpose of using a Fast Fourier
Transform (FFT) analyzer in vibration measurement?
A. To measure the DC offset of a signal
B. To convert a time waveform into a frequency spectrum
C. To calculate the overall vibration velocity
D. To filter out high-frequency noise
CORRECT ANSWER: B
Rationale: FFT mathematically transforms time-domain data into
frequency-domain data, allowing analysts to identify specific fault
frequencies.
Question 4: What is the phase relationship between the two ends of a
rotor experiencing static unbalance?
A. 0 degrees (in phase)
B. 90 degrees
C. 180 degrees (out of phase)
D. 270 degrees
CORRECT ANSWER: A
Rationale: In static unbalance, the heavy spot is at the same angular
position along the rotor length, resulting in in-phase vibration.
Question 5: What occurs when a machine operates at its natural
frequency?
A. The vibration amplitude decreases significantly
B. The machine automatically shuts down
C. Resonance occurs, causing a dramatic increase in vibration amplitude
D. The vibration frequency shifts to 2x RPM
CORRECT ANSWER: C
Rationale: Resonance is the condition where the excitation frequency
matches the system's natural frequency, leading to amplified vibration.
,Question 6: What is the most critical safety step before performing
hands-on vibration data collection?
A. Checking the data collector battery level
B. Ensuring machine guards are in position and secured
C. Calibrating the vibration sensor
D. Recording ambient temperature
CORRECT ANSWER: B
Rationale: Securing machine guards prevents entanglement or contact
with rotating components, which is the primary safety hazard during
hand-probe measurements.
Question 7: Which test is specifically used to detect turn-to-turn
shorts in motor windings?
A. Megohmmeter test
B. Surge test
C. Vibration analysis
D. Thermography
CORRECT ANSWER: B
Rationale: A surge test applies a high-voltage pulse to detect insulation
breakdown between turns in a motor winding.
Question 8: When using a megohmmeter, what does a very low
insulation resistance reading indicate?
A. The insulation is in excellent condition
B. The equipment is properly grounded
C. Moisture, contamination, or degraded insulation
D. The test voltage was too low
CORRECT ANSWER: C
Rationale: Low resistance indicates a conductive path, often caused by
moisture, dirt, or deteriorating insulation material.
, Question 9: How is the Polarization Index (PI) calculated?
A. 1-minute reading divided by 10-minute reading
B. 10-minute reading divided by 1-minute reading
C. 30-second reading divided by 1-minute reading
D. 5-minute reading divided by 10-minute reading
CORRECT ANSWER: B
Rationale: The PI is the ratio of the 10-minute insulation resistance to
the 1-minute insulation resistance, indicating insulation quality.
Question 10: What is a common application of infrared thermography
in a predictive maintenance program?
A. Measuring motor winding resistance
B. Detecting loose electrical connections and overloaded circuits
C. Analyzing lubricant chemistry
D. Measuring ultrasonic noise
CORRECT ANSWER: B
Rationale: Thermography detects abnormal heat patterns, which are
often caused by high resistance in electrical connections.
Question 11: Which temperature sensor has a negative temperature
coefficient (NTC)?
A. RTD
B. Thermocouple
C. Thermistor
D. Strain gauge
CORRECT ANSWER: C
Rationale: Thermistors are semiconductor devices whose resistance
decreases as temperature increases (NTC).
