"The new MFT1700 series from Megger tests low voltage electrical installations to BS7671. Providing all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations. The unique design allows it to be operated while mounted on the floor, a ladder-shelf, platform, and held or hung around the neck. The new MFT1700 series includes full input protection and safety warnings when a hazardous voltage is present. If live voltages exist on a circuit during insulation or continuity testing, the voltage is displayed on the screen. If this voltage exceeds a safe level, further testing is inhibited and a warning beep sounds. MFT1731 On-Site option is available complete with PowerSuite® Lite software. MFT1731 On-Site provides a professional solution to certification with electronic form completion from stored data within the MFT.
