The Elster Polyphase meter single disk technology, the total quality concept at every level of the manufacturing process and the right selection of materials, make that the characteristics of these meters remain unaltered in the most adverse operational environmental conditions. Variations in temperature, humidity, location, voltage or frequency as well as external magnetic fields, short-circuits and unbalanced load have little effect on these meters, that hold their accuracy over the whole operational range from 5% basic current to maximum current.
