Making testing faster

08 April 2019

An Auto Sequence facility has been added to Metrel's multi-function testers. It allows a selected range of tests to be completed at the press of a button. Each test is automatically compared to pre-set limits, passed or failed, and results displayed and stored.

Brendan Beaver, sales manager of Metrel, explains: “Most of us are familiar with the auto-RCD test on a multi-function tester; it speeds you though a routine set of tests, and gives the results at the end without you having to tramp backwards and forwards initiating each test. Imagine how good it would be if that same principle could be brought to other routine testing. Your machine getting on with the testing, and asking for your help when it needs it to speed you on to finish the job.”

Beaver believes the new Auto Sequence facility provides a solution. She says: “It saves so much time, and produces stable, repeatable results quickly.”

The Auto Sequence facility is pre-programmed in to Metrel multi-function testers, ensuring a cost-efficient and easy way of installation testing and improving operator safety. This system is suitable for situations where the same test is repeated continuously such as Electrical Installation Condition Reports (EICR). The results can be stored on-board the tester and then downloaded to an IET certificate.

The pre-programmed sequence of tests is selected by the operator depending on the part of the installation to be tested, the earthing system, whether the installation is single- or three-phase and whether there is an RCD present in the installation.

Having connected the test leads, and pressed the test button the tester will automatically perform the tests and indicate whether each test is passed or failed. It also tells the operator where their interaction is required.

Metrel says the key benefit to users of the Auto Sequence procedure is that they complete the testing up to five times faster than with ordinary methods.
