MW9660 Electrical Installation Tester

MW9660 is the instrument of choice for the installation safety testing on TT and TN systems. The large 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.

MW9660 contains integrated characteristics of fuses and RCDs for the automatic evaluation of the results. The tester is simple and easy to use. Each test has its own individual help screen describing how to connect the instrument and carry out measurements.

MW9690 performs continuity, insulation, RCD, loop, line, voltage, frequency and phase sequence tests required by the EN 61557 standard.

Features and Benefits

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 Loop Impedance 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
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
