Fluke 1662 Multifunction Installation Tester
The Fluke 1662 is a multifunction installation tester that gives you Fluke reliability and all the basic testing power you need for day-in, day-out installation testing. It verifies the safety of fixed wiring in domestic, commercial and industrial installations to IEC 60364 and local regulations, including the ETCI National Rules for Electrical Installations in Ireland and BS 7671 in the UK. In one tool it covers insulation resistance, continuity, loop impedance, prospective earth fault current and RCD testing.
As an authorised Fluke distributor, Powerpoint Engineering supplies the 1662 as the entry model in the 1660 series. It is easy and intuitive to use, with a switchable auto-start for RCD and loop tests and a self-test function that save time and give more confidence in your results.
What the Fluke 1662 tests
- Insulation resistance and continuity of conductors
- Loop and line impedance with prospective earth fault current
- RCD trip time and tripping current for type A and type AC devices in one test
- RCD ramp test, measuring switching time and tripping level
- Supply voltage and frequency checks
Features that save time
The switchable auto-start begins an RCD or loop test the moment the leads make contact, so repeat testing across a board is faster. A built-in self-test checks the instrument before you rely on it, and the rugged, intuitive design keeps the 1662 productive through a full day on site. Clear results and simple operation make it a reliable tool for electricians who certify installations every week.

Where the 1662 fits in the range
The 1662 is the basic, dependable choice in the 1660 series. If you need extra functions such as earth resistance and a variable RCD test current, step up to the Fluke 1663 multifunction tester. The series extends further to the 1664 FC, which adds an insulation pre-test, EV charger testing and Fluke Connect.

FAQs
Does the Fluke 1662 test to Irish and UK standards?
Yes. It tests to IEC 60364 and local regulations, which underpin the ETCI National Rules for Electrical Installations in Ireland and BS 7671 in the UK, covering insulation, continuity, loop impedance, prospective fault current and RCD testing.
Which RCD types can the Fluke 1662 test?
The 1662 tests type A and type AC RCDs, measuring trip time and tripping current in one test, plus a ramp test for switching time and tripping level. For type B (smooth DC sensitive) devices you need a tester rated for type B.
Does the Fluke 1662 need regular calibration?
Yes. To keep results traceable and defensible for certification, calibrate the instrument on a set interval. Our in-house laboratory calibrates and repairs Fluke installation testers and issues traceable certificates.
