1. Introducció
The Metrel MI 3102 BT EurotestXE is a versatile, multifunctional measuring instrument designed to perform a comprehensive set of installation safety tests in accordance with IEC/EN 61557 standards. This device supports automated testing sequences for TN, TT, and IT earthing systems, and is capable of performing ISFL measurements and IMD tests. It also offers online voltage monitoring, phase sequence testing, earth resistance measurement, illuminance measurement, and TRMS current measurement.
The EurotestXE features integrated characteristics of fuses and RCDs, enabling immediate PASS/FAIL evaluation of test results. All measurement data can be saved directly on the instrument and later transferred to a computer via EuroLink PRO software for detailed analysis and report generation.
Característiques principals:
- Insulation resistance testing with DC voltage de 50 V a 1000 V.
- Continuity of PE conductors with 200 mA DC test current (polarity change) and 7 mA test current (without RCD tripping).
- Line/Loop impedance and Loop impedance with Trip Lock RCD function.
- TRMS voltage and frequency measurement, and phase sequence testing.
- RCD testing for general and selective types (AC, A, F, B, B+).
- Earth resistance measurement using 3-wire and 2-clamps methods.
- First fault leakage current (ISFL) and Insulation Monitoring Devices (IMDs) testing.
- Automated test sequences for various earthing systems (Auto TT, Auto TN/RCD, Auto TN, Auto IT).
- Power measurements and harmonics analysis.
