Question 1

Video inspection equipment may include: mirrors, magnifying lens, and cameras.

Accepted Answer

Video inspection equipment can indeed include mirrors, magnifying lens, and cameras.

Question 2

Vibration measurement readings may include: frequency, acceleration, along with axial and radial displacement.

Accepted Answer

Vibration measurement readings can include frequency, acceleration, axial displacement, and radial displacement.

Question 3

Electrical system measurements may include: frequency, voltage, and __________.&#10;A) impedance&#10;B) current&#10;C) crest factor&#10;D) All answers are correct

Accepted Answer

All three options - impedance, current, and crest factor - are commonly measured in electrical systems, alongside frequency and voltage, as they provide important information about the performance and characteristics of the system.

Question 4

Test instruments for a preventative maintenance activity may include: multi-meter, tachometer, and __________.&#10;A) thermal imaging system&#10;B) vibration analyzer&#10;C) insulation resistance meter&#10;D) All answers are correct

Accepted Answer

All of the listed instruments can be useful in determining the condition of equipment and identifying potential maintenance needs. The thermal imaging system can detect abnormalities in temperature that indicate potential issues, the vibration analyzer can identify irregularities in equipment vibration that could indicate wear or damage, and the insulation resistance meter can test the integrity of electrical insulation. The multi-meter and tachometer are also valuable for measuring electrical and mechanical variables.

Question 5

Amplitude measurements that may be captured by a vibration analyzer include_______.&#10;A) Lumens&#10;B) Farads&#10;C) Displacement&#10;D) Henrys

Accepted Answer

Amplitude measurements in vibration analysis usually refer to displacement, which is the distance that the vibrating object moves from its rest position. Lumens are a measurement of light, Farads are a measurement of capacitance, and Henrys are a measurement of inductance, and are not related to vibration analysis.

Question 6

Thermal imaging is not a means to determine the condition of a bearing.

Accepted Answer

Thermal imaging can be used to detect the temperature of a bearing, which can provide some information about its condition. However, it is not a definitive way to determine the condition of a bearing and should be used in conjunction with other methods such as vibration analysis and visual inspection.

Question 7

Thermography equipment is useful in determining if cable splices or terminal connections have become loose.

Accepted Answer

Thermography equipment can detect irregular heat patterns caused by loose connections, making it useful in identifying potential issues with cable splices or terminal connections.

Question 8

Visual inspections may include: color, missing components, extent of wear, and corrosion.

Accepted Answer

Visual inspections can indeed include color, missing components, extent of wear, and corrosion as some of the things that can be observed with the naked eye.

Question 9

Data storage devices may include: micro SD card, USB thumb drive, and computer hard drive.

Accepted Answer

These are all examples of data storage devices.

Question 10

Wire insulation measurements are a good means of determining if a terminal connection has been removed.

Accepted Answer

Wire insulation measurements are used to determine the integrity of the insulation around a wire, not whether a terminal connection has been removed.

Question 11

Visual inspection items may include: color, missing hardware, cracks, and ________.&#10;A) corrosion&#10;B) abrasion&#10;C) leaks&#10;D) All answers are correct

Accepted Answer

The answer of Visual inspection items may include: color, missing...
