What are the types of calibration?
Electric calibration which focuses on the electric device input-output relationship.
What is the purpose of calibration?
Calibration refers to the act of evaluating and adjusting the precision and accuracy of measurement equipment. Instrument calibration is intended to eliminate or reduce bias in an instrument's readings over a range for all continuous values.
What are the method of calibration?
Calibration is the act of ensuring that a method or instrument used in measurement will produce accurate results. There are two common calibration procedures: using a working curve, and the standard-addition method. Both of these methods require one or more standards of known composition to calibrate the measurement.

What is called calibration?
Calibration means matching the standard value of the instrument to the master (True) Instrument value. Calibration in measurement technology and metrology is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy.
What is the requirement for calibration?
Two important parameters that should be defined for every calibration process are equipment tolerance and operating range of that instrument. Calibration tolerance is defined as the maximum allowable deviation between a standard of known accuracy and your test instrument.

Scale Span
It is defined as the difference between the largest and the smallest reading of the instrument.
Frequency Range
It is defined as frequencies over which measurements can be performed with a specified degree of accuracy. For example, an instrument has 0-300 V range and 0-150 Hz frequency range.
