Multi-function testers (MFTs) save electricians time by combining essential tests into one device. Steve Dunning, Managing Director at Martindale, explains how the latest models can simplify tasks, reduce errors and ensure compliance.

For electricians, having the right tools at your fingertips can make a big difference. Multi-function testers (MFTs), handheld devices that can perform a variety of electrical tests, are a good and necessary addition to a toolbox; they reduce time spent on-site and cut the chance of costly errors without sacrificing accuracy or compliance with the 18th Edition Wiring Regulations.

MFTs are used to test low voltage circuits and ensure that electrical installations are safe and meet regulations. They can perform a range of tests, including continuity tests, insulation resistance tests, earth fault low impedance tests and wiring polarity, among others. Because they combine so many tests into one easy to use device, it means less equipment to carry around, fewer cables to connect and, most importantly, less chance of making a mistake during testing.

MFTs are real time-savers and can make a big difference, especially on larger projects or jobs where deadlines are tight. By cutting out the need to swap between different devices, electricians can significantly speed up their work rate. Instead of recalibrating or setting up new testers for each different test, an MFT allows you to jump straight into the next task. For electricians working on multiple jobs or large-scale projects, this can make a huge difference to productivity.

Cutting out the errors

MFTs are designed to be simple; many have intuitive user interfaces with on-screen guides, which simplify even complex tests. As these devices walk the user through each step and flag any issues, electricians are far less likely to make errors or have to perform tests for a second time. It might seem like a small advantage, but these time-saving moments quickly add up.

But MFTs aren’t just about speeding up testing – they are incredibly precise too. Performing critical tests such as voltage measurements, earth resistance and insulation checks requires accuracy, and MFTs are designed to deliver reliable results. Some MFT models also come with onboard memory, so electricians can store test results directly on the device. This is a massive help when preparing reports or needing to verify compliance. Instead of manually recording every reading (and risking transcription errors), electricians can save the data digitally and generate professional, accurate reports later.

There is no doubt that clients notice when a job is done quickly and professionally. A reliable MFT not only helps electricians complete work to a high standard but also gives them the tools to back it up with solid test results. Clients appreciate detailed reports and MFTs that store and download results make creating them much easier. Being able to present clear, thorough data from tests helps build trust and makes the tradesman who does this look very professional.

For wholesalers who want to stock efficient MFTs to meet the demands of electricians looking to increase productivity, the new ET6000 Series from Martindale Electric is a practical and reliable solution. The range includes the ET6000, ET6300 and ET6500, which cover a wide variety of essential testing tasks and can be used on anything from simple installations to complex jobs. Each model is designed to perform all the critical measurements required for verifying the electrical safety of installations, including high-current and non-trip earth loop impedance testing, voltage measurement, phase sequence indication, and Auto RCD testing.

No confusion

Each model has a full-colour TFT display that clearly shows connection information and test results so there is never any confusion during testing and electricians can focus on the task without second-guessing themselves. The testers all come with a ‘Test and Go’ carry case and there’s no need to take them out – the unit can stay in its case even while it’s being used, protecting it on-site and cutting down on set-up time.

The ET6000 is the entry-level model, ideal for electricians who want a reliable installation tester that covers all essential functions required by the 18th Edition Wiring Regulations. As electric vehicles become more common, the demand for EV charger testing is growing so the ET6300 and ET6500 models are designed to help electricians stay prepared for the evolving requirements of electrical installations. The ET6300 model is EV-ready, making it a solid choice for those wanting to test electric vehicle charger points. Its accessory set includes stackable leads, the TL180 slimline test probe and a mains charger with rechargeable batteries. This model can also be upgraded at any time with the Martindale TL305EV adapter to enable EV testing capability. The flagship ET6500 model includes all the accessories of the ET6300 including the TL305EV adapter and has advanced features including an onboard memory for storing and downloading test results, great for electricians who need to generate compliance reports or manage large amounts of test data​.

For anyone serious about saving time and boosting productivity, investing in an MFT is an obvious choice. These all-in-one devices remove the hassle of juggling multiple tools, reduce on-site hours and deliver spot-on accuracy. It doesn’t matter whether the task is a complex installation or a routine check, an MFT makes the job easier, faster and more professional. With the right MFT to hand, electricians will be ready to handle whatever is thrown their way.
