METES - Meter Test Systems
Dramatic advances in the field of measurement technology and the use of state-of-the-art micro-electronics have led to the development of a new generation of electricity meters which are far more accurate than their predecessors of just a few years ago. As well as measuring the exact amount of energy used, a high level of integration enables electronic meters to perform a number of additional functions. As a result, these meters are also more sensitive to network irregularities. This means that regular testing is the only way to ensure that a meter functions correctly, both during final factory tests and during the entire life span of a meter.
