• 适用标准 / 规范(官网 Guidelines):CEI 64-8 · CEI 64-8 612.6.2 · CE MARK · DPR 462 del 22/10/2001 · EMC 2014/30/EU · EMC: IEC/EN61326 · IEC/EN61010-1 · IEC/EN61557-1 · IEC/EN61557-5 · LVD 2014/35/EU · UNE20460
官网原文(英文)
• 官网产品概述(英文原文):Compact earth resistance tester · M71 has been developed to measure earth resistance with 2 wires and 3 wires by voltammetric method in compliance with standard IEC/EN61557-1. · This device allows carrying out measurements with a wide measuring range (50k&Omega;) and an efficient internal automatic compensation of the disturbance effects found on the installations, and it is provided with an ergonomic design with electronic function selector for quickly carrying out the tests. The 2-wire method allows carrying out earth measurement by taking advantage of appropriate external masses as a reference (metal surfaces, tubes, neutral conductor, etc.), which is particularly useful in private environments where, because of logistic problems, it is not possible to use the 3-wire method.
