Question 1 of 10

1. Calibration:

Must always be undertaken annually

Must always be done by an accredited laboratory

A set of operations that establish, under specified operating conditions, the relationship between a measuring device and a traceable standard of a known reference and uncertainty

Is equivalent to MSA

Question 1 of 10

Question 2 of 10

2. Risks in the use of measuring equipment include:

Poor production supplier performance

The very high cost of undertaking calibration

The equipment could be damaged during use but any out of calibration condition would not be identified until the next due date

Maintenance of manufacturing equipment not done to schedule

Question 2 of 10

Question 3 of 10

3. A reference standard:

Is a part from the normal production process

Has to be purchased from an outside body

Can only be used once and then has to be destroyed

A reference for comparison, normally determined under laboratory conditions or using a more accurate instrument

Question 3 of 10

Question 4 of 10

4. How many reference standards are needed to undertake a bias study?

Question 4 of 10

Question 5 of 10

5. Bias:

Is the variation in calibration over time

Is the change in linearity over the operating range of the gauge

Shows the difference between the reference value and the observed average of measurements obtained by measuring the reference standard several times

Has to be performed at least annually

Question 5 of 10

Question 6 of 10

6. Stability is:

The change in linearity over time

The change in bias over time

The change if the reference value over time

The change in Gauge R and R over time

Question 6 of 10

Question 7 of 10

7. Linearity is:

The change in bias over the operating range of the equipment

A change in bias over time

Only determined during calibration

Is the change in repeatability over time

Question 7 of 10

Question 8 of 10

8. Bias, linearity and stability:

Has to be undertaken for every piece of measurement equipment

Is a useful way of helping understand and managing risk in the measurement process

Studies are always undertaken in the laboratory

Replace the need for calibration

Question 8 of 10

Question 9 of 10

9. The frequency of doing stability studies:

Has to be determined by the organization based on risk

Must be daily

Must be monthly

Must be done at least annually

Question 9 of 10

Question 10 of 10

10. A measurement of reference standard every day by the operator in the normal work environment is called:

Calibration

Linearity

Bias

Stability
