.c. determine the instrument control settings needed to pass the highest
percentage of test specimens run
Material must be reasonably centered in the test coil of a flaw detection system
because:
a. the coil would otherwise be out of balance
b. parts of the material furthest away from the coil, radially, may receive a less
sensitive inspection resulting in improper penetration
c. the flow of eddy currents around the product will be disturbed
d. lack of proper centering may change the phase adjustment of the instrument
- ANSWERS-b. parts of the material furthest away from the coii, radially, may
receive a less sensitive inspection
When you determine that a flaw detection instrument has been set up
incorrectly, or is defective, all material:
a. should be retested since the time correct set-up or proper operation was last
verified
b. accepted should be retested
c. rejected should be retested
d. none of the above - ANSWERS-a. should be retested since the time correct
set-up or proper operation was last verified
An eddy current system (60-cycle comparator type) will measure variations
caused by differences in:

d. all of the above - ANSWERS-d. all of the above
A length of tubing containing a notch running from end to end and having
uniform width and depth, when tested with an encircling self-reference
differential coil system, will produce:
a. erratic signals
b. a continuous, sustained signal
c. no signal
d. excessive signals - ANSWERS-C. no signal

test being conducted is referred to as:
a. Poisson's ratio
b. signal-to-noise ratio

The process of comparing the reading or output of an instrument, device, or dial
with a standard to determine the instrument's accuracy, capacity, or
graduations is referred to as:
a. calibration
b. differentiation
c. integration
d. phase shifting - ANSWERS-a. calibration
When'conducting an eddy current test using a differential comparison coil
arrangement that compares an external reference standard with the test
specimen, the system should be nulled or balanced:
a. with only the reference standard in one coil
