Precision Meter LZQJ-E

Precision Meter LZQJ-E


The Precision Meter LZQJ-E has been designed mainly for the registration of large quantities of energy e.g. for measurement at supply terminals. The meter is in accordance with VDEW-Specifications 2.1. The heart of the meter is the high precision measuring system. The application of an external auxiliary voltage supply enables a flexible application of the meter. Due to the plug-in technique it is quick and easy to change the meter.
