Unit 5 Flashcards
One of the easiest ways of troubleshooting or performing maintenance on equipment is by conducting a ___ ___.
visual inspection
A visual inspection can, and should be conducted ____, ____ and ____ equipment operations.
before, during and following
Before beginning an internal analysis, perform a visual inspection on the _____ of the equipment.
exterior
When inspecting equipment (like test equipment) that
requires periodic calibration, always check the ____ ____.
calibration sticker
Ensure it is within its due calibration date and that the piece of equipment is rated for the test to be performed. If the item is near or past the required calibration date, take the equipment item to the ___ ___ ___ ___ for recalibration because the equipment is considered to be non-operational.
Precision Measurement Equipment Laboratory (PMEL)
Any maintenance activity, such as an inspection, servicing, or
replacement that’s performed as part of a scheduled plan, rather than as a response to a breakdown.
Preventative Maintenance
What does PMI stand for?
periodic maintenance inspections
______ are often referred to as periodic, scheduled, or routine maintenance because the T.O. or commercial manual states how often the ____ must be conducted (e.g., monthly, quarterly, annually, etc….). This practice is a proactive approach to ensuring equipment is kept in peak operating condition.
PMIs
What does LWC stand for?
Local Work Cards
Because these inspections are performed on a routine basis, ___ ___ ___ are often created.
LWC
_____ is a form of problem solving. It is a logical, systematic approach to solving a problem, and making the equipment or system operational again.
Troubleshooting
What are the seven steps to the trouble shooting process?
- Identify the problem
- Establish a theory
- Test the theory
- Establish a plan
- Implement the solution
- Verify functionality
- Document the process
The following describes which step in the seven step troubleshooting process?
The first thing that you need to be aware of when troubleshooting
a problem is that the symptoms are not the problem. When troubleshooting, it is critical that you identify the underlying problem. What is causing the symptoms to manifest? Is there really a problem or is it just operator error? To do that, you should question the user. Ask detailed questions about when the symptoms occurred and why they may have occurred. If possible, try to re-create the issue. This can be extremely helpful when determining if anything has changed, because sometimes the symptoms will change over
time. It can also lead to figuring out what may have caused the initial problem.
Step 1: Identify the problem
The following describes which step in the seven step troubleshooting process?
After you have identified the base problem that is causing the symptoms, you will establish a list of probable causes. Try to create a
comprehensive list by brainstorming, asking other technicians, and/or researching the equipment history. Once you have a list of all the possible probable causes, use your technical knowledge to prioritize that list from most likely to least likely. Incidentally, be
sure to question the obvious. For instance, can you receive a signal but not transmit? You should probably look at the transmit circuit.
Establish a theory
The following describes which step in the seven step troubleshooting process?
Once you have established your theory of probable cause, you will need to test your theory to determine if it is, indeed, the actual cause. Your theory was created from the most likely probable cause, so you need to determine how best to test it. Using the system’s circuits & diagrams (Cs & Ds) to aid in testing your theory at the component level will greatly improve your ability to determine
the source of the issue.
Step 3: Test the Theory
