The Fluke 1662 Multifunction Installation Tester is designed for electricians, electrical contractors and maintenance professionals who need a reliable tester for day-to-day electrical installation testing. Built for fast and efficient verification work, the Fluke 1662 combines voltage, frequency, continuity, insulation resistance, loop impedance, line impedance, RCD testing and phase sequence indication in one professional instrument. Simple and intuitive to use, the Fluke 1662 helps technicians test electrical installations quickly and confidently. It checks wiring polarity to detect broken neutral wires, measures insulation resistance and continuity, calculates prospective earth fault current and prospective short-circuit current, and supports RCD testing including trip time and ramp testing. The Fluke 1662 also includes Z-max memory for loop tests, helping users evaluate the highest loop test value more easily. Supplied with a hard carrying case, standard test lead set, heavy-duty mains cord, zero adapter, padded carrying strap and remote control probe, this installation tester is a practical solution for professional electrical testing and compliance work.
