Metrel MI 3122 SMARTEC Z Line-Loop/RCD Tester

The MI 3122 SMARTEC Z Line-Loop/RCD Tester from Metrel has been designed for live circuit testing. It has the ability to perform Ze and Zs testing, automated RCD testing and line resistance testing for three phase systems.

This rechargeable unit has an online voltage monitoring system allowing the electrician to monitor activity on three simultaneous voltages in real-time. The built in fault loop impedance tables allow for automated evaluation of loop readings.

With red and green indicator lights, onscreen pass/fail gauge and onboard help screens allowing the electrician the most straight forward testing, this tester is an ideal and accurate tester.

All test results can be quickly saved and referenced on the unit while out on site and can be downloaded via the optional A1291 EuroLink PRO software or the EuroLink Pro Plus software which also allows automatic printing onto NICEIC forms.

The Metrel MI 3122 Z Line-Loop/RCD Tester can perform tests to meet the 17th Edition and Part P building regulations and is an ideal investment.

Key Features of the Metrel MI 3122 SMARTEC Z Line-Loop / RCD Tester

• Help screens: unit comes complete with built-in help screens for referencing on site.
• Automatic loop evaluation: built in loop impedance tables allow automatic evaluation of the loop resistance compared to the regulations.
• Online voltage monitoring: monitors all 3 voltages in real-time.
• Phase sequence test: requested by BS7671:2008 17th Edition.
• Upgradeable: if changes occur to the regulations, software.
• TripLock function: Zs (RCD) function performs a loop test without tripping the RCD/RCBO.
• Built-in charger & rechargeable batteries: unit has an inbuilt charging circuit and comes complete with a set of rechargeable NiMH batteries.
• RCD auto: automated RCD testing reduces circuit test time.
• Downloadable: downloads via RS232 or USB cable directly to the PC via the optional A 1290 and A 1291 software.
