Sample questions
01What is meant by 'traceability' in calibration?
- AThe ability to locate any instrument on the plant from a database
- BA record showing who carried out each calibration and when
- CThe maximum permissible error stated on the calibration certificate
- DAn unbroken chain of comparisons to national standards
Why: Traceability means the calibration can be traced through an unbroken chain of comparisons back to national standards.
02What is the typical calibration frequency for process instrumentation?
- AQuarterly
- BEvery 5 years
- CMonthly
- DAnnually
Why: Annual calibration is typical for most process instrumentation, though critical applications may require more frequent calibration.
03What is 'hysteresis' in instrument calibration?
- AThe deviation of the output from a perfect straight-line response
- BThe smallest change in input that produces a detectable output change
- CThe difference between upscale and downscale readings at the same input
- DThe gradual drift of the reading away from the true value over time
Why: Hysteresis is the maximum difference between upscale and downscale readings at the same input value.
