Instrument Calibration Quiz

What is the definition of calibration?

• Comparing the displayed value of a measuring instrument with a reference instrument standard

• Estimating the measurement uncertainty of a device

• Determining the accuracy and repeatability of a measuring instrument

• Measuring the input and output values of an element

Why is calibration needed?

• To establish traceability in the measurement process

• To determine the measurement uncertainty of a device

• To measure the deviation or error of a measuring instrument

• To ensure quality output products

What is the term used to describe how close a measurement is to the true value?

• Repeatability

• Accuracy

• Hysteresis

• Measurement Uncertainty

What is the term used to describe the ability of a measuring instrument to sequentially position to the same target value?

• Repeatability

• Accuracy

• Measurement Uncertainty

• Hysteresis

What is hysteresis?

• The deviation of a measuring instrument from the true value

• The result of imprecision in measuring devices

• The measure of the state's ability to sequentially position to the same target value

• The value displayed by the test equipment depending on the input parameter measured previously

What is measurement uncertainty?

• The larger of the limit of the instrument multiplied by the number of measurements taken

• The result of imprecision in measuring devices

• The measure of the state's ability to sequentially position to the same target value

• The deviation of a measuring instrument from the true value

Which of the following is a base unit in the International System of Units (SI)?

• Celsius

• Pascal

• Kelvin

• Newton
