Top 10 Questions for Technician, Helper, Instrument Interview

1. Explain the difference between calibration and adjustment?

Calibration is the process of comparing the accuracy of a measuring instrument to a known standard and making adjustments as necessary to ensure the instrument is reading correctly. Adjustment, on the other hand, is the process of making physical changes to an instrument in order to change its output or behavior.

2. What are the different types of calibration methods?

• Point calibration: This method involves measuring the instrument at a single point and adjusting it to read correctly at that point.
• Multi-point calibration: This method involves measuring the instrument at multiple points and adjusting it to read correctly at each point.
• Span calibration: This method involves measuring the instrument at two points and adjusting it to read correctly at those two points.
• Zero calibration: This method involves adjusting the instrument to read zero when there is no input.

3. What is the purpose of documentation in calibration?

Documentation is essential for keeping track of the calibration history of an instrument, including the date of calibration, the person who performed the calibration, the calibration method used, and the results of the calibration. This documentation can be used to verify the accuracy of the instrument, to identify any problems that may arise, and to comply with regulatory requirements.

4. What are the different types of instruments used in calibration?

• Standard instruments: These instruments are used as a reference to calibrate other instruments.
• Transfer instruments: These instruments are used to transfer calibration information from one instrument to another.
• Verification instruments: These instruments are used to verify the accuracy of other instruments.

5. What are the different factors to consider when selecting a calibration method?

• The accuracy of the instrument
• The type of measurement being made
• The environmental conditions
• The cost of the calibration

6. How often should instruments be calibrated?

The frequency of calibration depends on a number of factors, including the accuracy of the instrument, the type of measurement being made, the environmental conditions, and the manufacturer’s recommendations.

7. What are the consequences of not calibrating instruments?

• Inaccurate measurements
• Failed products
• Lost time and money
• Safety hazards

8. What are the different types of instrument technicians?

• General instrument technicians
• Specialized instrument technicians
• Calibration technicians
• Repair technicians

9. What are the qualifications for an instrument technician?

• A high school diploma or equivalent
• Training in instrument technology
• Experience in calibrating, repairing, and maintaining instruments
