Mass is unique among the base units of the International System of Units in being defined in terms of a physical artifact. The world-wide equivalence of mass measurements is vital to trade and commerce and there are increasing demands on laboratories to demonstrate quality assurance in the measurements. Weights, balances and belt weighers are used extensively in laboratory and industrial measurements, but although these instruments are easy and simple to use, they are complex instruments. This three-day course introduces you to balances, weighing and belt weighers, and provides you with useful frameworks and concepts needed to avoid the common pitfalls of weighing.
Who should attend?
This course is relevant to people who use, check or calibrate laboratory or industrial weights (mass standards and belt weighers), and particularly to people who are involved in laboratory accreditation and QA programmes. Primary emphasis is placed on the theory, principles and practise of calibration of weights and the use, test and verification of belt weighers. The course is designed to provide value for senior technicians, engineers and technical staff from a wide range of industries, calibration and testing laboratories involved in laboratory accreditation and establishing measurement traceability under an ISO quality system. The course curriculum is applicable to both calibration and manufacturing processes. Participants should have a basic level of mathematics: multiplication, division, uses of graphs and tables. Being acquainted with GUM uncertainty analysis will prove helpful but not necessary during the course.
The course curriculum is based on Danish Technological Institute’s more than 100 years of experience in designing test setups, calibration in various fields, verification and as a leading partner in industrial development for Danish and international companies. Besides being the National Reference Laboratory for Liquid Flow and Contact Thermometry in Denmark, this experience includes measurement of pressure and force among others as well as operation of data acquisition systems.
The course includes a review of the principles of weighing metrology, the measurement system, traceability and aspects of the calibration process which can affect the results. The course covers essential knowledge of calibration, calibration system error analysis and completion of calibration reports. Furthermore the course provides the participants with useful frameworks and concepts for a wide range of factors influencing on the measurement system e.g. the problem of buoyancy, the laboratory environment for mass measurement, care and handling of weights, reporting calibration data and uncertainties, calculation of measurement uncertainty and how to select equipment meeting the user’s requirement. The course will engender confidence in your measurements.
There will be a number of hands-on exercises to develop practical skills and theoretical exercises to get accustomed with the significant influence parameters. The course is designed to be highly interactive to enable you to benefit from the experience of the other participants and the presenters. Time is included to give the participants an opportunity to discuss specific problems and the emphasis is to ensure that you can apply your new knowledge in your own organisation.
The course includes an exam, a certificate of completion and a certificate of the exam result.

After the course you will have obtained:
- An overview of the underlying physical principles and technologies for weights and belt weighers.
- Practical knowledge in order to choose the right equipment for weighing, proving and sampling and in order to be able to resolve any ensuing problems in relation to uncertainty and inaccuracy of weighing measurements.
- Knowledge about installation, periodic maintenance, calibration techniques and ability to analyse the instrument's operating environment to determine how it may affect its performance.
- An understanding of the role of trade measurement within the national measurement system.
- Skills to meet the requirements of traceability and quality standards of ISO 17025 or in-house requirements of traceability and quality standards.
- Knowledge needed to verify/certify a belt weigher in accordance with the uniform test procedures
Furthermore you will have learned about:
- Basic measurement concepts
- Why measurements sometimes do not work
- Measurement design
- Making measurements traceable
- Principles of calibration
- Assessing the uncertainty in measurements
Weighing is often thought of as a simple task, but in fact calibration involves a much wider range of tasks including checking that the weight/weighing belt is working properly under test, ensuring that the instrument has a traceable calibration, using the correct calibration/verification method and calculating the uncertainty of the measurement.
The primary aim of this course is to provide sufficient information on the above topics to enable users to choose the equipment and methods that meet their needs and to provide a firm platform assuring that installation and use of weighing devices is performed correctly. All concepts during the course are designed to provide direct knowledge to value. This innovative program provides a pathway for people currently working with weighing to further develop their knowledge and skills.
