Electronic Balance Calibration

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 practice 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 Instructors

Mr. Lee Shih Mean, Mr. David Lim and Mr. Lim Gin Yen are, respectively, Senior Metrologist and Senior Technical Executives in mass measurements. Shih Mean, David and Gin Yen 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 in charge of the Mass & Force Laboratory in NMC. He is a qualified SAC-SINGLAS technical assessor. He has also served as a technical peer reviewer for many overseas national metrology institutes.
