Megger MFT1721 Multi-function Tester - 1008-123 This range of 3 Megger multifunction installation testers are designed for low voltage electrical installations to BS7671. They provide all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations. MFT1711 This device is the entry level 18th edition tester offering CAT IV, 3 and 2-wire non-trip loop testing with resistance and fault current display frequency measurement. It also boasts the largest, brightest and clearest display on the market. This now adds a 1 kW insulation test range, Auto RCD tests, 10 mA RCD, programmable (VAR) RCD, ZMAX and true RMS voltage management. MFT1721 This device offers all the benefits of the MFT1710, but with additional auto RCD testing and adding phase rotation. In addition, it has 3-phase RCD testing and current measurement with the optional clamp. It provides an additional 100V insulation test range, true RMS voltage measurement, mV sensor input and Type B RCD testing. MFT1731 This is the most sophisticated of the 18th edition models, it brings Type B RCD testing, 3-pole earth electrode testing to a downloading and rechargeable instrument. The device is supplied with a large soft carry case with sufficient space for the tester, test leads and some tools. It has enabled additional earth electrode testing options such as 3-pole ART electrode testing and stakeless electrode testing. Clamps are optional accessories.
