Fluke 1662 Multifunction Installation Tester

Solid performing entry-level tester from Fluke's flagship range

The 1662 puts more power in your hands by quickly and efficiently testing to all local regulations, protecting appliances that may be inadvertently connected to the system under test, and making it easy to share test results over your smartphone. Safety and performance are two of the most critical requirements for any electrical system. Good quality insulation, a properly working grounding system and active protection assure the safety of people, electrical systems and buildings, and protect them against electrocution, fire and other equipment damage.

The versatility of the Fluke Multifunction Tester

Insulation-continuity test: our installation tester does the job.
Fluke installation testers can be used to perform an insulation-continuity test, which is designed to diagnose and prevent the breakdown of the insulation in various parts of the electrical system such as wires, transformers and motors. The quality of insulation is critical to assure proper, uninterrupted and safe functioning of electrical circuits.

Checking RCD devices with a Fluke multifunction tester.
Our versatile installation testers can also check the proper functioning of residual-current devices (RCDs). RCDs are designed to disconnect quickly to mitigate the harm caused from electric shock and to avoid current leaks that may lead to fire and other dangerous situations. Our installation testers assure that RCDs can properly perform this important task.

The perfect loop testing tool: a Fluke installation tester.
Loop testing is a quick, convenient, and highly specific method of evaluating an electrical circuit for its ability to engage protective devices (circuit breakers, fuses, RCDs). A ground loop determines the effectiveness of protective devices.

Resistance measurement of grounding systems.
The electrical installation testing abilities of the Fluke installation tester also include verification tests to ensure that a system's resistance is low enough to provide protection to people, equipment and structures. A properly functioning grounding system is a critical safety feature of an electrical system.
