Principles of Calibration

This course is a 4 day workshop in the principles of electrical calibration.

The course Topics covered are

                 Introduction to Metrology DC Ratio
                         Why Calibrate? DC Voltage
                           SI Units AC-DC Transfer
                               Statistics Resistance
                                   Specifications DMM Calibration
                                         Measurement errors Guarding, Grounding & Shielding
                                             Definitions Cables & Connectors
                                                 Primary Units ISO 9000 & Quality

The workshop is designed to train engineers & technicians in the general principles of electrical calibration. It is designed to make them more proficient in understanding why they are asked to do a particular job, how they can better interact with their colleagues and where they can focus any future learning requirements. The delegates should have some familiarity with the use of electronic test gear though this is not essential.

A brief history of metrology is given which progresses on to the relationships between Fundamental Measurements and the idea of Quality. These topics are developed to explain the pressures in the market place for reliable calibration.
This leads naturally to the requirements of Traceability in the chain of calibration measurements, where it originates from and how it devolves to the final customer. Statistics are covered lightly in order to focus their importance on how measured values are attained and are a core part of understanding Specifications.
This is arguably the most important subject of all. The main types of instrument specification types are covered with examples of why not relying on the most prominent figures, as stated on a data sheet, is so important.

Guarding, Grounding, Shielding, Cables & Connectors are highlighted with their specific importance to measurement integrity explained.
Each remaining subject in the list above is covered in some detail, also the delegates will be required to perform a few calculations as necessary to exercise and reinforce a point.

At the end of the course the delegate should have a clearer idea of their job function, will be more productive in their daily task, be much more aware of the pitfalls in electrical measurement and to more positively contribute to the quality performance of the department.
