Sri Chakra Scienticfic Sercices Calibration Engineer Interview Questions, Process, and Tips

Calibration is the process of adjusting and verifying the accuracy of a measuring instrument or tool.

• Calibration ensures that a measuring instrument or tool provides accurate and reliable results.

• It involves comparing the readings of the instrument to a known standard or reference.

• Adjustments are made to the instrument until it provides accurate readings.

• Calibration is important in industries such as manufacturing, aer...read more

Calibration ensures accuracy and reliability of instruments and equipment.

• Calibration helps to maintain the quality of products and services.

• It ensures that measurements are consistent and reliable.

• Calibration helps to identify and correct errors in instruments and equipment.

• It is necessary for compliance with industry standards and regulations.

• Examples of instruments that require calibration include thermometers, pres

Accuracy refers to how close a measurement is to the true value, while acceptance criteria are predetermined standards for what is considered acceptable.

• Accuracy is a measure of how close a measurement is to the true value, while acceptance criteria are predetermined standards for what is considered acceptable.

• Accuracy is determined by comparing a measurement to a known standard, while acceptance criteria are determine...read more

Least count is the smallest measurement that can be taken, while resolution is the smallest change that can be detected.

• Least count is determined by the instrument's precision and accuracy

• Resolution is determined by the number of digits displayed on the instrument

• For example, a ruler with a least count of 1 mm can measure up to 1 mm accuracy, while a digital caliper with a resolution of 0.01 mm can detect changes as sm

RTD measures resistance changes with temperature while thermocouple measures voltage changes with temperature.

• RTD has a linear relationship between resistance and temperature while thermocouple has a non-linear relationship between voltage and temperature.

• RTD is more accurate and stable than thermocouple.

• RTD is suitable for precise temperature measurements while thermocouple is suitable for high-temperature measurement...read more

Pressure gauge measures pressure of gases or liquids, vacuum gauge measures pressure below atmospheric pressure, compound gauge measures both.

• Pressure gauge measures pressure of gases or liquids

• Vacuum gauge measures pressure below atmospheric pressure

• Compound gauge measures both

• Pressure gauge is used in applications such as hydraulic systems, air compressors, and refrigeration systems

• Vacuum gauge is used in application...read more

Calibration procedure for pressure gauge involves comparing the gauge readings with a reference standard.

• Start by selecting a suitable reference standard with a known accuracy.

• Ensure the pressure gauge is clean and in good condition before calibration.

• Connect the pressure gauge to the reference standard using appropriate fittings and tubing.

• Apply a series of known pressures to the reference standard and record the corr...read more
