Fluke Installation Testers

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.

A multifunction installation tester (also called MFT) by Fluke verifies the safety of electrical installations in domestic, commercial and industrial applications. This electrical installation testing ensures that fixed wiring is safe and correctly installed, meeting the requirements of most local electrical wiring regulations.

Our multifunction tester offers great versatility

You can use the Fluke installation tester for various types of tests:

  • Insulation-continuity test: our installation tester does the job

    Fluke multifunction 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 installations testers can also check the proper functioning of residual-current devices (RCDs). These devices disconnect a circuit whenever the electric current between the energized and neutral conductors is not balanced. An imbalance indicates that there is a leakage current outside of the system. This may be caused by a person who accidentally touches the energized part of the circuit or by insufficient insulation (excessive moisture or worn out, poor-quality insulation materials). RCDs are designed to disconnect quickly to mitigate the harm caused by such shocks and to avoid current leaks that may lead to fire and other dangerous situations. Our multifunction testers assure that RCDs can properly perform this important task.

  • The perfect loop testing tool: a Fluke installation tester

    Another possible application for the handy Fluke installation tester is loop testing. This 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. Our multifunction tester offers the crucial ability to measure it, so that problems can be detected and corrected.
  • 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. It is used to mitigate the risk when exposed metal parts come in contact with dangerous voltages should an installation fail. Building structures are protected by grounding systems that divert the energy of lightning strikes straight to ground. Connections to ground limit the build-up of static electricity when handling flammable products or when repairing electronic devices.
