Multifunction Testers

Multifunction testers are handheld devices used to verify the safety of installations in domestic, commercial and industrial settings. These testers ensure that fixed wiring is safe and correctly installed to meet relevant local standards and safety requirements.Multifunction testers are ideal for testing a range of electrical parameters such as voltage, earth resistance, loop impedance and more. Many multifunction testers offer additional features such as Bluetooth, allowing you to store and transfer data from the device to a computer or mobile device.Here a RS Components we have sourced multifunction testers from leading brands such as Fluke, Megger, Gossen Metrawatt, RS PRO, and many more.

What are Multifunction testers also known as?

Multifucntion Testers can be categorised with many different naming conventions, they are also commonly called 'Electrical Testers' and also 'Multifunction Installation Testers'. However, even though they use slightly different names they all essentially do very similar things and due to their nature can be used in a range of different situations.

Uses of Multifunction Testers

Multifunction testers perform a variety of tests, including:Insulation-continuity tests: Diagnose breakdown of the insulation in various parts of the electrical system such as wires, transformers and motors. The quality of insulation is critical in ensuring uninterrupted and safe functioning of electrical circuitsChecking RCD devices: Check the proper functioning of residual-current devices (RCDs). RCDs are designed to disconnect quickly to mitigate the harm caused by electric shock and to avoid current leaks that may lead to fire and other dangerous situations.Loop testing: A quick, convenient, and specific method of evaluating an electrical circuit's ability to engage protective devices (circuit breakers, fuses, RCDs). A ground loop determines the effectiveness of protective devices.Resistance measurement of grounding systems: Verification tests to ensure that a system's resistance is low enough to provide protection to people, equipment and structures.

Application

Multifunction testers are used electrical engineers for electrical installation work in both commercial and industrial applications.
