What is a multifunction tester?

It’s a single device that carries out a wide range of electrical safety tests. It replaces the need for multiple test instruments by combining insulation testing, continuity testing, loop impedance, RCD testing and more into one unit.

What tests can you perform with the tester?

A multifunction tester can carry out a wide range of electrical safety tests, including insulation resistance testing, continuity testing, loop testing and line impedance testing, RCD testing, and phase rotation checks. Some advanced models also support EV charger testing and data logging.

What is the difference between a basic and advanced multifunction tester?

Basic models cover the core safety tests needed for most installations. Advanced models often include features such as Bluetooth connectivity, onboard memory, EV testing support, and report generation.

Do multifunction testers need calibration?

Yes. To ensure accurate results testers should be calibrated regularly. Many electricians choose annual calibration to meet quality standards and audit requirements.

Multifunction Testers

Multifunction testers are essential tools for electricians and electrical engineers. They are used to carry out a wide range of electrical safety tests on wiring and installations.

They can check wiring polarity, test insulation resistance, measure loop and line impedance. Carry out RCD tests, and complete phase rotation checks. All of these tests can be done using one single device.

This means you do not need to switch between different testers on the job. It saves time, reduces effort and helps keep work running smoothly.

They also support compliance with the 18th Edition wiring regulations, helping electricians work safely and meet current industry standards.
