MI 3125B is a lightweight, easy to use multifunctional installation safety tester. The ability to test B-type (DC sensitive) RCDs, integrated characteristics of fuses and RCDs, help screens, bright LEDs for PASS / FAIL evaluation of test results, online voltage monitor, compatibility with the PC SW EuroLink PRO are just some of distinctive features of the MI 3125B.

MEASURING FUNCTIONS

Insulation resistance with DC voltage
Continuity of PE conductors with 200 mA test current with polarity change
Continuity of PE conductors with 7 mA test current (continuous measurement) without RCD tripping
Line impedance
Loop impedance
Loop impedance with Trip Lock RCD function
TRMS voltage and frequency
Phase sequence
RCD testing (general and selective, type AC, A and B)
Earth resistance (3-wire method).

OTHER FEATURES

LED Pass/Fail indicators: two LED in-dicators 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.
Earth resistance measurement: instrument performs 3-wire earth resistance testing with two additional rods.
Built-in fuse tables: this unique feature allows automatic evaluation of the line / loop impedance compared to the regulations.
Online voltage monitoring: monitors all 3 voltages in realtime.
Upgradeable: if changes occur to the regulations, upgrades can be made to the firmware to keep the instrument 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 M?.
Trip Lock function: Zs (RCD) function performs a loop impedance test without tripping the RCD.
Multisystem 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. B type RCD testing is supported.
PC SW EuroLink PRO included in the the standard set enables downloading of test results and parameters and creation of test reports.

SOFTWARE
