A free guide from MK Test Systems

Using an outdated, inefficient tool to conduct loop resistance testing on aircraft in your facility can be dangerous and costly.

The most commonly used tool for LRT testing is the ‘yellow box’ LRT 906-10246-3, or a multi-meter. Neither of these are the best tool for the job, particularly if you’re working on Boeing aircraft.

If you use the LRT but have issues with the ageing technology or the size and weight of the kit, you don’t need to accept the issues you and your team likely have with your current tool. 

Similarly ineffective is a bond or multi-meter. It simply cannot detect open circuits in complex parallel networks, which can result in bad joints passing inspection. It’s not only inaccurate, it is dangerous.

What criteria should you consider when selecting a new tool?

Our free guide covers the top ten criteria to consider when selecting a new LRT loop resistance tester tool. It includes guidance notes on the following points and more:

  • Battery life
  • Reliability of readings
  • Safety classification
  • OEM approval
  • Technology
  • Delivery leadtime
