This document describes the features and characteristics of the GMC-I Gossen-Metrawatt GmbH METRISO®1000A insulation tester, including its suitability for measuring insulation resistance in voltage-free devices and systems, insulation testing of earth conductors, protective conductors, and bonding conductors, quick testing with a signal lamp, low impedance measurement, voltage measurement up to 1000V, and minimal use of batteries.
The METRISO 1000A is an insulation resistance tester designed for measuring resistance of voltage‑free devices up to 1000 V. It features quick testing with a signal lamp, low‑impedance measurement, and a 1000 V voltage measurement range, all while minimizing battery consumption.
The handbook lists technical data, reference conditions, safety classifications (IP 52, protection class II), EMC compliance, mechanical dimensions, included equipment, and optional accessories such as cable sets and floor probes. It also details battery requirements, service life expectations, and applicable standards (IEC, VDE, EN).
