Module 1: Calibration Principles & Techniques
  • This Module offers an introduction to “basic concepts of calibration” .
  • Deals - in brief the overall concept of Calibration, Terminology used and Principle of Traceability.
  • Calibration Techniques and a note on Accuracy are touched upon.
  • The concept of Uncertainty in Measurement is introduced along with Proficiency Testing.
  • A brief note on pre – requisite for Certification is added. This Module is to be attended by Technicians, Calibration Engineers and persons responsible for Laboratory Management at various levels.
      Topics Covered in detail

    Uncertainty of Measurement (UOM) *
    The process of Measurement involves various Elements & Parameters – characteristics & behaviour of Master Instrument, environmental parameters, opening conditions and variations in resources performances, competency of personnel. All these introduce an element called “Uncertainty” in the process of Measurement resulting in “certain amount of Uncertainty” in the “observed value of Measurement”. This Module goes into the depth of identifying and quantifying each of the parameters and estimating the combined effect of all those parameters on the measured parameter. It is suggested that Calibration Engineers make it a point to attend the Module, a basic technical requirement of ISO/IEC 17025:2005.
    Concept gives total confidence in the measurement taken which ensures the validity of measurement during Calibration to an Internationally / Nationally accepted reference, through an unbroken chain. A better understanding of Traceability makes the Calibration Engineers and the functional management staff to ensure and keep the chain of Masters used for Calibration properly calibrated – an important criterion for Accreditation.

    Best Measurement Capability (BMC)
    BMC is the minimum amount of Uncertainty, a Calibration Laboratory will introduce in the process of Measurement of a parameter an instrument is intended to measure generally. It depends upon the capability of a laboratory’s resources – human, infrastructure facility, equipment, environment etc. Scope of Accreditation of a Laboratory is based on BMC with regard to the particular parameters. Understanding the concept and estimation of BMC require thorough knowledge of estimation of UOM. The Best Measurement Capability of the Laboratory to a great extent depends upon the technical competency of the Calibration Engineers. Laboratory Functional In – charges therefore need to understand the concept as the Laboratory has to be technically assessed for its BMC to consider the same for scope of Accreditation.
  • Trainees are requested to bring their own Scientific Calculators for the calculation of Uncertainty of Measurement.

    Practical Training

    The practical training covers imparting Standard Calibration Procedures to carry out Calibration in Mechanical, Electro – Technical & Thermal Measurements.

    This includes Calibration of DMM, Multi – function Calibrators, Electronic Controllers, Voltmeters, and Ammeter to name a few in the field of Electro – Technical Measurement.

    In Thermal Measurements Calibration Techniques for RTD, TC, Temperature Gauges, Temperature Switches, Temperature Transmitters are included.

    CalibrTesters, and Pressure Switches etc. ation of Pressure Gauges, Pressure Calibrators, Pressure Transmitters, Dead Weight are covered in Mechanical Measurements.
