Question 1

When interpreting measurement readings, ____ is the value that occurs the most frequently in the sample data.&#10;A) mean&#10;B) median&#10;C) mode&#10;D) standard deviation

Accepted Answer

The mode is the value that occurs the most frequently in the sample data. While the mean and median are also measures of central tendency, they are not necessarily the most representative value in cases where there is a significant amount of variability in the data. The standard deviation is a measure of dispersion, rather than central tendency.

Question 2

Electrical controls are used to maintain the quality of a product when operated by ____.&#10;A) robotic devices&#10;B) qualified personnel&#10;C) consumers&#10;D) PLCs

Accepted Answer

Qualified personnel are responsible for operating electrical controls to maintain product quality.

Question 3

In processes in which there is a reliance on an operator to control the actuators that influence the quality of products, alarm circuits are usually not necessary.

Accepted Answer

Alarm circuits are necessary in processes where operator error can lead to poor product quality, and can provide warnings or shut down the process if necessary.

Question 4

One method of automating the quality check of a part is to have a third party system analyze the part and send the results to the control system.

Accepted Answer

This statement is true. By having a third party system analyze the part, it eliminates the potential for human error and provides more accurate and consistent results. These results can then be sent directly to the control system for further processing and analysis.

Question 5

____________________ design in process control means that even if the measurement device is not functioning, bad parts will not pass through the system unnoticed.

Accepted Answer

The answer of ____________________ design in process control means that...

Question 6

A data acquisition system is generally a(n) ____ that allows for the direct connection of process sensors.&#10;A) output device&#10;B) self-contained circuit&#10;C) fiber optic cable&#10;D) EtherNet network

Accepted Answer

A data acquisition system is a self-contained circuit that allows for the direct connection of process sensors. It typically involves analog-to-digital converters, signal conditioning, and data storage capabilities. Output devices, fiber optic cables, and EtherNet networks may be used in conjunction with a data acquisition system, but they are not the system itself.

Question 7

In an automated system, ____ may be used to measure specific characteristics of the part against test limits.&#10;A) transistors&#10;B) limit switches&#10;C) tolerances&#10;D) transducers

Accepted Answer

Transducers are devices that convert one form of energy to another, such as converting pressure to electrical signals. They can be used in an automated system to measure specific characteristics of a part, such as dimension, pressure, or temperature, against test limits.

Question 8

A(n) ____________________ chart is frequently applied to a continuous measurement process, and plots measurement values sequentially along a horizontal axis.

Accepted Answer

The answer of A(n) ____________________ chart is frequently applied to...

Question 9

____________________ defines the range of values acceptable in meeting the specifications of quality.

Accepted Answer

The answer of ____________________ defines the range of values acceptable...

Question 10

Sensors not calibrated properly can cause quality control systems to become inaccurate.

Accepted Answer

Sensors are crucial components in quality control systems as they detect and measure certain parameters to ensure the quality of products or processes. However, if sensors are not calibrated properly, they can provide incorrect data, leading to inaccurate quality control results. Therefore, it is important to regularly calibrate sensors to maintain their accuracy and reliability.
