The MI 3125 is a multifunctional installation safety tester which is distinguished by lightweight design and usability. Integrated characteristics of fuses and RCDs, help screens, red and green LEDs for PASS / FAIL evaluation of test results online voltage monitor make the MI 3125 ideally suited for fast and easy testing of electrical installations.

MEASURING FUNCTIONS

TRMS voltage and frequency
Continuity
Insulation resistance
RCD testing (type AC and A)
Fault loop / RCD Trip Lock impedance
Line impedance
Phase sequence

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 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 unit up to date.
Polarity swap: automatic polarity re-versal 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.
