3. Types of Calibration

There are three major types of calibration:

1) Absolute Calibration: This type of calibration is done by comparing the reading from an instrument with a known reference value.

2) Relative Calibration: This type of calibration is done by comparing the reading from an instrument with another instrument that has already been calibrated.

3) Zero Calibration: This type of calibration is done by adjusting the zero point on an instrument so that it agrees with a known reference value.

It can further be categorized into various types depending on the equipment being calibrated and the purpose.

Such as:

Instrument Calibration: Adjusting instruments to ensure accuracy and precision in their measurements.

Temperature Calibration: Ensuring temperature-measuring devices like thermometers and probes are accurate.

Pressure Calibration: Adjusting pressure gauges and sensors to accurately measure pressure.

Flow Calibration: Ensuring flow meters and sensors provide accurate measurements of fluid flow.

Dimensional Calibration: Calibration of tools and equipment used for measuring dimensions such as calipers, micrometers, and rulers.

Electrical Calibration: Adjusting electrical measuring instruments like multimeters and oscilloscopes to ensure accurate readings.

Mass Calibration: Ensuring scales and balances provide accurate weight measurements.

Time Calibration: Synchronizing clocks and timers to a standard time source.

Each type of calibration requires specific procedures and standards to ensure accuracy and traceability.
