MI 3125 InstalTestCOMBO is the appropriate instrument for the installation safety testing on TT and TN systems. The bright graphic display with backlight ensures that results, indications, measurement parameters and messages are clear, visible and easy to read. The red and green LEDs on either side of the display provide a clear PASS / FAIL evaluation of test results. InstalTestCOMBO contains integrated characteristics of fuses and RCDs for the automatic evaluation of the line / loop impedance results. The handling of the instrument is designed to be as simple and clear as possible. Each test has its own individual help screen describing how to connect the instrument into the installation and how to perform a measurement. MI 3125 InstalTestCOMBO performs continuity, insulation, RCD, loop, line, voltage, frequency and phase sequence tests required by the EN 61557 standard.

Key Features:

LED Pass/Fail indicators: two LED indicators for PASS / FAIL evaluation of test results are placed on both sides of the LCD.
Help screens: instrument comes complete with built-in help screens for referencing on site.
Built-in fuse tables: this unique feature allows automatic evaluation of the line / loop impedance results compared to the regulations.
Online voltage monitoring: monitors all 3 voltages in real-time.
Earth resistance measurement: instrument performs 3-wire earth resistance testing with two additional rods.
Upgradeable: if changes occur to the regulations, upgrades can be made to the firmware to keep the unit up to date.
Polarity swap: automatic polarity reversal on continuity test.
Insulation range: wide range of insulation test voltages from 50 V to 1000 V, reading up to 1000 MΩ.
Trip Lock function: Zs (RCD) function performs a loop impedance test without tripping the RCD.
Multi-system testing: tests on single and multiphase TT and TN systems.
Built-in charger & rechargeable batteries: unit has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries.
RCD auto: automated RCD testing procedure significantly reduces test time.
