Uncertainty measurement March 13, 2023 3 NL € 2,259.00


The increasing demand for reliable measurement results increases the need for a responsible estimate of the uncertainty in measurements and/or measurement systems. The EA-4/02 document contains the European requirements for uncertainty calculation for accredited laboratories. When applied correctly, this document provides you with the assurance of a correct and generally accepted measurement uncertainty determination. This training is a practical translation of this document. On the basis of a ‘recipe’ you will receive relevant background information and insight into and a feeling for sources of uncertainty.
You will also practice yourself and in class in setting up and calculating uncertainty budgets according to EA-4/02

Introduction temperature and temperature measurement March 6, 2023 1 NL € 995,00


Temperature is a commonly measured quantity. Insufficient knowledge about temperature and temperature measurement can lead to many mistakes that can have a direct impact on the results and/or costs of production, quality or safety. During the training, the problems associated with the different types of thermometers are made visible and discussed. This leads to more knowledge and insight into measuring temperature. After the training, the participants have more insight into which type of temperature sensor and which version is most suitable for their measurement process.

DCLF April 3, 2023 4 NL € 3,255.00


The training provides insight into measurement and calibration techniques in the low-frequency electrical field. It is indicated how sources of error in measurement setups can be discovered and how they should then be processed in the total uncertainty of the measurement. Afterwards, the students can realize and analyze calibration setups in the low-frequency electrical field.

In addition to an introduction to quality assurance and the (inter)national metrological structure, the following topics are discussed:

  • precision measurement techniques for low-frequency electrical measurements (DC and AC voltage and current, resistance, impedance)
  • factors affecting electrical measurements
  • uncertainty of electrical measurements

Practical exercises and demonstrations are an important part of the course and help to apply the theoretical knowledge in practice.

General pressure measurement

Training Date Days Language Cost
General pressure measurement April 10, 2023 2 NL € 1,675.00


Today, digital pressure meters are available for measuring absolute pressures with a resolution of 0.001 mbar at a measuring range of 2 bar. At the highest pressure, neglecting a gas column of 1 cm already gives a deviation of approximately 0.002 mbar.

Pressure measurement plays an important role in industry. More processes are being automated, which is why pressure sensors with an analog and/or digital output are playing an increasingly important role. The uncertainties with which pressure measurements are carried out in industry are getting smaller and smaller. A good knowledge of the uncertainty contributions of various influencing factors is therefore important.
The student is introduced to all facets of pressure measurement and must be able to recognize effects that influence a pressure measurement and be able to perform an uncertainty analysis afterwards.
In addition to theory, attention is paid to practical exercises/experiments.

An effective measurement management system ensures that measurement equipment and measurement processes are suitable for their intended use and are important in achieving product quality objectives. The purpose of a measurement management system is to manage the risks in which measurement equipment and measurement processes can produce incorrect results that affect the quality of the service product. The methods used for the measurement management system range from verification of basic equipment to the application of statistical techniques in the measurement process. All necessary for the implementation of a measurement management system and can be useful in improving measurement activities and therefore the quality of products. This training discusses the generic requirements and provides tools for the management of measurement processes and the metrological confirmation of measuring equipment to demonstrate that the metrological requirements are met.

This training focuses on the competence management of laboratory employees, the measurement processes and software, the management of the measurement files and equipment. Specific attention is paid to the characteristics of the measuring equipment in order to make a proper diagnosis for an optimal (re)calibration program of the equipment. An explanation is also given about the traceability of measurements to the measurement standard and the associated measurement uncertainty. This is linked to the quality management system, which also checks if equipment does not meet the requirements.
