Performing tests on the accuracy of installed populations of electricity meters has traditionally been a daunting and expensive task, requiring complex and often cumbersome testing units and necessitating highly-trained operating staff. Accordingly, the goal of low-cost and rapid on-site meter re-certification has traditionally remained elusive.

For a period of nearly three years Lord Consulting, a New Zealand-based consulting and test equipment company, has been working alongside its Canadian partner, Consulab, to address the inherent technical challenges in achieving cost-effective, compact, lightweight, and flexible testing equipment that would also offer intuitive and simple operation.
