Metrology Upgrading Programme - Electronic Balance Calibration

About Metrology Upgrading Programme (MUP)

MUP aims to contribute to the productivity of the industry through transferring and sharing knowledge and expertise in measurement science and technology with the industry. This programme comprises metrology courses, workshops, and seminars which are held throughout the year. Technical staff and researchers who work on measurements and instrumentation in the various industrial sectors will benefit from the programme.

Course Outline

This course covers the fundamental principles of weighing, mass, balance calibration and measurement uncertainty. Practical issues related to the use, maintenance and calibration of balances and the evaluation of measurement uncertainties associated with the evaluation of balance performances and the ISO 17025 compliant way of reporting the calibration results will be covered. Participants will have the opportunity to experience working with actual weights and get hands-on practise on how to calibrate an electronic balance firsthand. This course will be useful for engineers, researchers and consultants involved in precision mass measurement that needs precise and accurate balances to ensure the highest quality products and measurement results.

Course Instructor

Mr. Lee Shih Mean and Mr. David Lim are, respectively, Senior Metrologist and Senior Technical Executive in mass measurements. Both Shih Mean and David have many years of experience in the areas of mass and balance calibration. They are responsible for the establishment and maintenance of mass standards in Singapore, and have conducted many training courses for the industry over the years. Shih Mean is the Laboratory Lead of the Mass & Force Laboratory in NMC. He is a qualified SACSINGLAS technical assessor. He has also served as a technical peer reviewer for many overseas national metrology institutes.
