Electrical testing

TECHNICAL expert James Dillon is backing an innovative multimeter test lead as a route to smarter analysis of electronic systems.

James, who runs training company Technical Topics, now also sells the TESlite smart multimeter lead.

The lead, developed by a mechanic in the US and approved by Volvo, lets users load circuits for more meaningful electrical test results.

“It allows you to load a circuit and validate the supply and ground,” said James, who uses the test lead during his own diagnostic work.

“It can quickly validate both for detecting problems affecting current flow. It’s something I’ve seen a lot of technicians struggle with,” he added.

The TESlite also features a steady-tip pin design which stops the problem of slipping when measuring electrical terminals and replaceable electrodes which mean snapped tips can be easily replaced.

The lead sells for £76 + VAT. For more information, contact James’s training company Technical Topics on 01278 671 919 or email sales@techtopics.co.uk. To see James’s latest technical article, turn to page 12.
