The eGauge is a powerful, highly accurate piece of monitoring hardware. However, it is essential to configure the eGauge properly, or the readings obtained will not be correct. Even on identical installations the exact settings may vary, depending on how the eGauge and CTs are installed. The document below covers the various aspects of basic eGauge configuration (assuming monitoring is done exclusively with CTs and voltage taps - remote devices are only briefly covered in this document).
Technical support is available to assist with configuration, but there is no guarantee the device configuration will be set correctly.
