Metrel Multifunction Tester Overview
Metrel multifunction testers are versatile tools designed for professionals conducting comprehensive electrical testing on domestic, industrial, and medical installations in compliance with standards like IEC/EN 6155.
Metrel multifunction testers often support a wide range of tests, including insulation resistance with DC voltage (50V to 1000V), continuity of PE conductors with polarity reversal, line and loop impedance, and earth resistance using 2- and 3-wire methods. They can also offer RCD testing (Type AC, A, F, B) with automated procedures and phase sequence verification. Select models include online voltage monitoring for real-time readings and built-in rechargeable batteries for extended use.
Outstanding features of Metrel multifunction testers vary by model but often include:
- Automatic Test Sequences: Simplify compliance testing for TT, TN, and IT systems.
- True RMS Voltage and Frequency Measurements: For accurate readings across non-linear waveforms.
- Bluetooth and PC Connectivity: Allows for direct data transfer and report generation using Metrel ES Manager software.
- Integrated Help Screens: Provides guidance on-site for efficient troubleshooting.
- Built-in Fuse Tables: Automatically evaluate line/loop impedance results.
- Trip Lock Functionality: Conduct loop impedance tests without tripping RCDs.
Applications include electrical safety inspections, fault detection, preventative maintenance, and installation troubleshooting in environments like hospitals, industrial sites, and renewable energy facilities. Metrel multifunction testers are essential for ensuring electrical safety and performance across a range of low voltage installations.
