Operation

This test lead is intended for use with a Megger DLRO2 to measure bonded conductors. For example, the resistance of lightning receptors to earth for large equipment in production, or in-situ during commissioning or maintenance, or following repair
The KC series enable construction of long test leads in 50 m increments suitable for testing large structures.
A test lead will consist of the appropriate instrument connector and asset clips at each end of a KC50C (50 m) or KC100C (100 m) lead. One or two KC50E (50 m) extension leads may be added to the assembly to extend the length.
For assemblies using more than one cable, the KC50E extension reel should be unwound and removed from its drum first: lift the extension cable connector from the slot in the drum and pass it though the hole in the drum wall. Connect the extension to the next cable to be unwound and repeat the process.
Ensure that 4 mm test terminals are correctly connected to the DLRO2: mating red to red and black to black
All tests must be carried out in accordance with the equipment manufacturers’ procedures and test limits
Before testing tall structures, ensure that any static potential is fully discharged by connecting an additional ground wire to the installed lightning protection cable at the base of the structure
When working with tall structures, consider the risks from carrying heavy equipment and unreeling cables at height. Arrange a safe procedure to protect those working below and at height during setting-up, testing and removing the test connections, especially when bad weather, high winds or precipitation add to the risk
