Calibration

Term from Laboratory Work industry explained for recruiters

Calibration is the process of checking and adjusting measurement equipment to ensure it gives accurate results. Think of it like making sure a scale shows the correct weight or a thermometer shows the right temperature. In laboratory and quality control jobs, calibration is crucial because incorrect measurements can lead to failed experiments or faulty products. This process involves comparing equipment readings against known standards and making necessary adjustments. It's similar to how you might check your watch against the official time to make sure it's correct, but for scientific equipment.

Example Interview Questions

Senior Level Questions

Q: How would you set up a calibration program for a new laboratory?

Expected Answer: A good answer should cover creating schedules for different equipment types, establishing documentation systems, training staff, selecting reference standards, and ensuring compliance with industry regulations.

Q: How do you handle out-of-tolerance situations in critical equipment?

Expected Answer: Should discuss investigation procedures, impact assessment on previous measurements, documentation requirements, corrective actions, and communication with affected departments.

Mid Level Questions

Q: What documentation do you maintain for calibration activities?

Expected Answer: Should mention calibration certificates, equipment history records, uncertainty calculations, traceability documentation, and maintenance logs.

Q: Explain how you ensure calibration standards are maintained properly.

Expected Answer: Should discuss proper storage conditions, handling procedures, regular verification against higher standards, and tracking expiration dates.

Junior Level Questions

Q: What is the difference between accuracy and precision?

Expected Answer: Should explain that accuracy is how close a measurement is to the true value, while precision is how close repeated measurements are to each other.

Q: What basic tools and equipment do you use for calibration?

Expected Answer: Should be able to list common calibration tools like standard weights, thermometers, voltage meters, and explain their basic use.
