Fluke 1662

Fluke 1662 – Multifunction Installation Tester

Overview

The Fluke 1662 is a reliable installation tester built for everyday electrical installation verification. It measures AC/DC voltage and frequency, checks wiring polarity including broken neutral conductors, tests insulation and loop and line resistance, and includes RCD test routines. Designed for safety, speed and compliance with local installation standards, it comes with practical features like auto-start for certain tests and memory (Z-Max) for loop tests.

Key Features

• AC/DC voltage measurement with true-rms

• Frequency measurement

• Wiring polarity check to detect broken neutral wires

• Insulation resistance test at multiple voltages (100 V, 250 V, 500 V, 1000 V)

• Loop and line impedance tests

• Prospective earth fault current calculation and prospective short-circuit current calculation

• RCD (Residual Current Device) trip time and current measurement, including variable current and ramp test

• Phase sequence indicator

• Memory for maximum loop values (Z-Max)

• Zero adapter to compensate for test leads and mains cord resistance

• Hard carrying case, remote control probe, lead set and strap included
