Metrel Multifunctional testers

The Metrel multifunctional tester is an appropriate device for the safety testing and installation on TT and TN system. The results, indications, measurement parameters and messages are clear, visible and easy to read due to the large graphic display with backlight. It contains integrated characteristics of fuses and RCDs for the automatic evaluation of results. The handling of the instrument is designed to be as simple and clear as possible. Each test has its individual help screen describing how to connect the instrument into the installation and how to perform measurements. This tester performs continuity, insulation, RCD, loop, line, voltage, frequency and phase sequence tests. It has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries.

Supplied With: Instrument EurotestCOMBO, test lead, 3 x 1.5m, Schuko-plug test cable, power supply adapter + 6 NiMH rechargeable batteries, Type AA, test probe, 3 pcs (blue, black, green), crocodile clip, 3 pcs (blue, black, green), set of carrying straps, short instruction manual, instruction manual on CD, handbook on CD and calibration certificate.

Features and Benefits

• Automated RCD testing procedure significantly reduces the test time

• Automatic polarity reversal on continuity test

• Built-in loop impedance tables allow automatic evaluation of the line / loop impedance results compared to the regulations

• Monitors all three voltages in real time

• Multi-system testing to test on single and multiphase TT and TN systems

• Two LED indicators for pass/fail evaluation of test results are placed on both sides of the LCD

• Upgrades can be made to the firmware to keep the unit up to date

• Wide range of insulation test voltages from 50V to 1000V, reading up to 1000mΩ

• Zs (RCD) function performs a loop impedance test without tripping the RCD

Applications

• Initial and periodic testing of domestic and industrial installations

• Testing of single and multiphase systems
