Kamstrup 351B Installation and User Guide

  • Hello! I've reviewed the user manual for the Kamstrup 351B electricity meter. This document provides detailed information on the meter's operation, display indicators, and safety guidelines. It also explains how to interpret the readings and utilize the various features such as the LED indicator and push button. The document also includes installation diagrams and dimensions. I'm ready to answer your questions about the meter and what you can find in the document.
  • What is the meter used for?
    What should I do before working on the meter?
    What do the L1, L2 and L3 segments indicate?
