Product Details

METREL MI 3125B Eurotest COMBO Multifunctional Installation Safety Tester

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 MO.
• 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.
