Performance Characteristics (Static_1)

What does the term 'Span' refer to in the context of instruments and measurement systems?

• Difference between upper and lower range

• The relationship between input and output

• The ability to detect small changes in the value of a measurement

• The range of different input values with no change in output

Which characteristic of an instrument is defined as the ability to register the same reading when a measurement is repeated?

• Accuracy

• Sensitivity

• Precision

• Repeatability

What is the main difference between Precision and Accuracy in measurement systems?

• Precision is the relationship between input and output, while Accuracy is the range of values

• Precision is the probability of performance, while Accuracy is the ability to maintain performance

• Precision is the range of variation, while Accuracy is the ability to repeat measurements

• Precision is the ability to detect small changes, while Accuracy is the closeness to the actual value

What does the term 'Dead space' represent in the context of instruments?

• The greatest range of variation allowed

• The ability to detect small changes in the value of a measurement

• The probability of performance for a specific period of time

• The range of different input values with no change in output

Which characteristic describes the maximum error that can be expected in a value and is closely related to accuracy?

• Calibration

• Tolerance

• Reliability

• Dead space

What is the aim of calibration in the context of instruments and measurement systems?

• To assign standard values to equipment

• To ensure the instrument meets its accuracy specification

• To improve the accuracy of measurements

• To maintain the balance between cost and risk

What does the term 'Reliability' refer to in the context of a measuring system?

• The probability of performing functions for a specific period

• The range of values that can be determined by an instrument

• The ability to maintain performance over time

• The relationship between input and output

Which characteristic of an instrument is defined as the ability to maintain its standard of performance over a prolonged period of time?

• Stability

• Reliability

• Calibration

• Tolerance

What is the main purpose of repeatability in a measuring system?

• To ensure the instrument meets its accuracy specification

• To maintain the balance between cost and risk

• To show agreement between successive measurements under the same conditions

• To improve the accuracy of measurements

Which characteristic of an instrument represents the degree to which a measurement represents the actual value?

• Sensitivity

• Precision

• Repeatability

• Accuracy
