Multifunction testers have become a staple in an electrician’s kitbag as they put the finishing touches to any installations or rewiring work.
Electrical safety standards govern how those in the trade must operate, and these handy bits of kit can make sure you’re compliant with every facet of your next job.
Here’s a rundown of everything you need to know about these devices.

What Are Multifunction Testers?
You might hear or see multifunction testers referred to as Electrical Testers or Multifunction Installation Testers. Be safe in the knowledge that all three do the same job.
MFTs can be used to check and diagnose issues with a systems insulation, ensure residual-current devices are operating safely and determine how well-grounded a system is.
You can check measurements such as voltage, earth resistance, loop impedance and more using a multifunction tester, while several top models also include connectivity to devices such as computers and smartphones, so you can produce safety reports in a fraction of the time.
How Much Do Multifunction Testers Cost?
A very basic tester might set you back in the region of £100. For this price, you can expect a basic device that will offer you a handful of readings in standard measurements such as voltage, resistance and current.
These handheld devices are ideal for checking appliances and smaller circuits.
At the top end of the scale, you could pay north of £4,000 for an MFT with all the bells and whistles. These heavy-duty devices are typically used to check heavy machinery and building-wide systems. They may even include built-in computers to get reports from at a click of a button.
How Do You Use Multifunction Testers?
Most MFTs work by plugging into the end of circuits at a socket. From there it is possible to test different parameters manually, while many devices over automatic functions that will gauge a number of fields without your input and give readings swiftly.
What Are the Benefits of Multifunction Testers
- Speed: Conducting multiple tests using one device will obviously save you time. The functionality of many multifunction testers can also shave hours off these complicated procedures as you don’t need to move around a site from circuit to circuit as much. And of course, as you’re well aware, time = money!
- Safety: As you don’t need to unplug and reattach multiple devices, you lessen the chances of yourself and your staff getting hurt or shocked by an electrical system. These devices also improve safety in the area long after your gone, with obvious benefits to residential and commercial properties.
- Cost: Even if you stump up a bit extra for an MFT with greater functionality, it’s likely still going to cost you less than gathering up individual devices. Not to mention it’s easier to carry one bit of kit around than lug a load with you everywhere.
