Voltimum product reviewer, Tony Cable, gives his verdict on the new MFT1741 from Megger which features an industry-first 'confidence meter' to ensure fast and repeatable non-trip loop testing.
Fast and repeatable non-trip loop testing – which in the past has been difficult to guarantee particularly on noisy circuits – is now easily achieved with a high level of confidence using the new MFT1741 multifunction installation tester from Megger.
Key differences between this and other multifunction testers are completely new internal hardware architecture, a novel algorithm to generate the loop test results, and a display that shows the degree of confidence that can be placed on the results.
Reliable loop testing results
When loop testing on a quiet circuit, the MFT1741 quickly returns a provisional reading and, at the start of the loop test, an arc is displayed. This very rapidly diminishes to a single element, indicating that the user can be highly confident of the result. This process is usually much faster than the standard test time of 15 seconds. On quiet circuits the final result is typically available within eight seconds.
Our product tester, Tony Cable, has long been a fan of Megger's electrical installation testers throughout his 60-year career in the electrical trade. What did he think of the new features added to the brand's latest multifunction tester? Fin out in the video below.
