Gage blocks are used to calibrate calipers and micrometers (among other things). They are made of metal or ceramic and must have very accurate lengths and very flat measurement surfaces.How do you check the flatness of a gage block?
- A.
By holding it up to the light and sighting down the long edge
- B.
By looking at it through an optical flat under polarized light
- C.
By feeling it with your hand
- D.
With a measuring wand
Correct Answer
B. By looking at it through an optical flat under polarized lightExplanation
To check the flatness of a gage block, one can look at it through an optical flat under polarized light. This method allows for the detection of any irregularities or deviations in the flatness of the measurement surface. The polarized light helps to enhance the visibility of any imperfections, making it easier to assess the flatness of the gage block accurately.Rate this question:

There need to be defined procedures and schedules for carrying out checks needed to maintain confidence in the calibration status of…
- A.
Reference standards
- B.
Primary, working, and transfer standards
- C.
Reference materials
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The correct answer is "All of the above" because in order to maintain confidence in the calibration status of reference standards, primary, working, and transfer standards, as well as reference materials, defined procedures and schedules for carrying out checks are necessary. These checks ensure that the calibration status remains accurate and reliable, ultimately maintaining confidence in the measurements and results obtained from these standards and materials.Rate this question:

All the following are correct regarding calibrated equipment except:
- A.
Can be labeled to indicate calibration status
- B.
Can be coded to indicate calibration status
- C.
Can be otherwise identified to indicate the status of the calibration
- D.
All equipment in the laboratory is assumed to be calibrated, so no action or labeling is required.

Equipment that has been mishandled gives suspect results, is defective, or gives suspect results shall be…
- A.
Taken out of service
- B.
Clearly marked as being out of service.
- C.
Decommissioned and discarded immediately
- D.
A & B only
Correct Answer
D. A & B onlyExplanation
Equipment that has been mishandled may give suspect results or be defective. Therefore, it should be taken out of service to prevent further use and potential harm or errors. Additionally, it should be clearly marked as being out of service to ensure that it is not mistakenly used. Decommissioning and discarding the equipment immediately may not be necessary if it can be repaired or restored to proper functioning. Therefore, the correct answers are A & B only.Rate this question:

The following support equipment requires calibration except
- A.
Incubators
- B.
Water baths
- C.
Stir plates
- D.
Thermometers
Correct Answer
C. Stir platesExplanation
Stir plates do not require calibration because they are not used for measuring or controlling temperature or any other parameter. They are simply used for stirring substances in a laboratory setting. On the other hand, incubators, water baths, and thermometers are all equipment that require calibration to ensure accurate and precise measurements and control of temperature. Calibration is necessary to maintain the reliability and validity of these instruments in scientific experiments and processes.Rate this question:

While calibrating the balance one morning, you find the weights do not fall within the specified range, you:
- A.
Clean the balance and try again
- B.
Contact your supervisor
- C.
Do nothing
- D.
Just watch it
Correct Answer
A. Clean the balance and try againExplanation
If the weights do not fall within the specified range while calibrating the balance, the best course of action is to clean the balance and try again. This is because the weights may not be accurate due to dirt or debris on the balance, which can affect the calibration process. By cleaning the balance, you ensure that it is free from any contaminants that may interfere with the accuracy of the weights. Trying again after cleaning will give a better chance of obtaining accurate results. Contacting the supervisor may be necessary if the issue persists or if further assistance is needed. Doing nothing or just watching it will not solve the problem.Rate this question:

The outcome of the comparison can result in one of the following, except...
- A.
No significant error being noted on the device under test
- B.
A significant error being noted but no adjustment made
- C.
An adjustment made to correct the error to an acceptable level
- D.
Nothing really happens
Correct Answer
D. Nothing really happensExplanation
The given options describe the possible outcomes of a comparison. The first option states that no significant error is noted on the device under test. The second option mentions that a significant error is noted but no adjustment is made. The third option states that an adjustment is made to correct the error to an acceptable level. The correct answer, "nothing really happens," implies that none of these outcomes occur. It suggests that there is some other consequence or result of the comparison that is not mentioned in the given options.Rate this question:

Establishing traceability is accomplished by a formal comparison to a standard that is directly or indirectly related to all except one.
- A.
City standards
- B.
National standards
- C.
International standards
- D.
Certified reference material
Correct Answer
A. City standardsExplanation
Establishing traceability is the process of ensuring that measurements or test results can be related to a known reference standard. In this context, traceability is achieved by comparing the measurement or test result to a standard that is directly or indirectly related to it. City standards, national standards, and international standards are all examples of reference standards that can be used to establish traceability. However, certified reference material is not directly or indirectly related to the measurement or test result, making it the exception in this case.Rate this question:

Calibration may be required for the following reasons, except...
- A.
A new instrument
- B.
After an instrument has been repaired or modified
- C.
When a specified time period has elapsed
- D.
During a critical measurement
Correct Answer
D. During a critical measurementExplanation
Calibration is the process of adjusting an instrument to ensure its accuracy and reliability. It is necessary for a new instrument to ensure that it is properly calibrated before use. Similarly, after an instrument has been repaired or modified, calibration is needed to ensure that it is functioning correctly. Additionally, calibration is required when a specified time period has elapsed to account for any potential drift or changes in the instrument's accuracy. However, during a critical measurement, calibration is not necessary as it may disrupt the measurement process and introduce errors.Rate this question:

When does the calibration process begin?
- A.
With the design of the measurement instrument
- B.
With the design of the calibration process
- C.
With whatever measurement instrument you have at hand
- D.
You can begin at any time.
Correct Answer
A. With the design of the measurement instrumentExplanation
The calibration process begins with the design of the measurement instrument because it is important to ensure that the instrument is accurate and reliable before using it for measurements. By designing the instrument with calibration in mind, any potential errors or inaccuracies can be identified and corrected early on, leading to more accurate measurements. Starting the calibration process at this stage also allows for adjustments to be made to the instrument design if necessary, ensuring that it meets the required standards for measurement.Rate this question:
