This kit is designed to allow users to get maximum usage from their DLRO10HD and DLRO10HDX, digital low resistance
ohmmeters (Ducter) in industrial LV environments. In these environments commissioning testing and scheduled
maintenance testing of individual connections can provide real benefits for added safety, energy efficiency and future reliability,
including fire prevention.
Many applications require making test lead connections to small contacts, which can also be in difficult locations to access.
This Industrial application kit allows the connection of 4 mm shrouded plugs of suitably rated building wiring style test leads,
maintaining the all-important CATIII rating of the DLRO10HD and DLRO10HDX instruments. A selection of lead sets fulfill
the requirements for the vast range of applications in this environment.
This kit enables safe, convenient testing of applications such as measuring power cable core resistance from one end,
measuring crimp, cable lug, bus bar connections, and circuit breaker/switch contacts plus much more common industrial
applications.
