Reliable Relevant Electrical Measurements
Good electrical measurement starts with being clear on why you are making the measurement, including the decisions that will come from the measurement results.
This course focuses on skills for making good electrical measurements. Good measurement starts with being clear on why you are making the measurement, including the decisions that will result from the measurement results. These skills are relevant whether the measurements are being made in a calibration laboratory or on the factory floor. Students will learn how to choose appropriate instruments, interpret instrument specifications, make use of the information in calibration certificates and use an appropriate measurement process.
After completion of the course students can be expected to decide how accurately an electrical measurement needs to be made and how best to achieve that accuracy with available equipment.

Principal Research Scientist | Electricity
Laurie has spent 40 years working as a metrologist specialising in electrical measurements. He is responsible for the 10 V Josephson Voltage Standard, which is New Zealand’s standard of dc voltage. In 1997 he spent 10 months working with the team at the NIST, Boulder, Colorado laboratories who developed the Josephson array chip that is the heart of this standard. He has carried out research into developments of this technology that allow the synthesis of arbitrary low-frequency waveforms. Laurie has been active in many areas of electrical metrology, including DC voltage, current and resistance.
In 1999 Laurie developed the Reference Step Method for measuring dc voltage ratios for resistive dividers up to 1000 V and has since then applied it to calibrating both dc voltage sources and meters over the same range. Several NMIs are using this method for dc voltage scaling. In 2006 he applied the core principle of this method to create the Current Reference Step Method, which can be used to scale from a low current to a much higher current (hundreds of amperes). Laurie has been a technical expert for many IANZ accredited electrical calibration laboratories and has peer-reviewed several NMIs in the Asia-Pacific region.
Distinguished Scientist | Electricity
Keith’s early scientific work was with developing primary standards of impedance, starting with a mechanical-based capacitance standard. The discovery of the quantum Hall effect in 1980 (by Klaus von Klitzing) led to a period of intense international research, and Keith contributed to the international effort that ultimately led to the adoption of the quantum Hall effect as the new standard of resistance.
He has significant experience with developing national quality infrastructures from his time spent as Director of MSL and as Chairperson of the Asia-Pacific Metrology Programme. He has provided strategic advice in Malaysia, Chile, the Philippines and Myanmar. Keith has worked closely with the New Zealand electricity supply since 1993 to support the development of metrology codes of practice for metering installations. A significant continuing part of his work has been the provision of training courses and software to assist Approved Test Houses with the certification of metering installations.
Keith has been technical expert or peer reviewer for many IANZ accredited laboratories in New Zealand and as a technical peer reviewer for national metrology institutes in the Asia-Pacific region.
