The process of evaluating the measurement results of the instrument to be calibrated with the known measurement results exceeding the appropriate accuracy and correctness limits is called instrument calibration. If any changes are found, calibrate the instrument so that it can provide accurate readings and values. It is very common for any instrument to lose calibration after prolonged use. After the calibration process is over, the instrument can be used again.
Calibration for:
A key measurement
If the instrument has experienced adverse conditions and cannot give correct readings.
When the output does not match the substitute instrument.
Drastic changes in weather
Cycle test of the instrument
Instruments for measuring length, temperature, pressure, etc. should be periodically calibrated according to certain standard measurement values according to the manufacturer's preference. The calibration method depends on whether the instrument is calibrated regularly or occasionally, and is used for special tasks that require highly calibrated instruments.
